Budding is the art of multiplying plants by causing the leaf-bud of one species or variety to grow upon the branch of another. The operation consists in shaving off a leaf-bud, with a portion of the wood beneath it, which portion is afterwards removed by a sudden jerk of the operator's finger and thumb, aided by the budding-knife. An incision in the bark of the stock is then made in the form of a T; the two side lips are pushed aside, the bud is thrust between the bark and the wood, the upper end of its bark is cut to a level with the cross arm of the T, and the whole is bound up with worsted or other soft fastening, the point of the bud being left exposed.
In performing the operation, a knife with a thin flat handle and a blade with a peculiar edge is required. The bud must be fully formed; the bark of the stock must separate readily from the wood below it; and young branches should always be chosen, as having beneath the bark the largest quantity of cambium or viscid matter out of which tissue is formed. The maturer shoots of the year in which the operation is performed are the best. The autumn is the best time for budding, though it may also be practised in the spring. Research Budding
A calendar (named from the Latin calendarium, from calendce, the first day of the month), is a record or marking out of time as systematically divided into years, months, weeks, and days.
The periodical occurrence of certain natural phenomena gave rise to the first division of time, the division into weeks being the only purely arbitrary partition. The year of the ancient Egyptians was based on the changes of the seasons alone, without reference to the lunar month, and contained 365 days divided into twelve months of thirty days each, with five supplementary days at the end of the year.
The Jewish year consisted of lunar months of which they reckoned twelve in the year, intercalating a thirteenth when necessary to maintain the correspondence of the particular months with the regular recurrence of the seasons.
The Greeks in the earliest period also reckoned by lunar and intercalary months, but after one or two changes adopted the plan of Meton and Euctemon, who took account of the fact that in a period of nineteen years, the new moons return upon the same days of the year as before. This period of nineteen years was found, however, to be about six hours too long, and subsequent calculators still failed to make the beginning of the seasons return on the same fixed day of the year. Each month was divided into three decads.
The Romans at first divided the year into ten months, but they early adopted the Greek method of lunar and intercalary months, making the lunar year consist of 354, and afterwards of 355 days, leaving ten or eleven days and a fraction to be supplied by the intercalary division. This arrangement continued until the time of Julius Caesar. The first day of the month was called the calends. In March, May, July, and October the 15th, in other months the 13th, was called the ides. The ninth day before the ides (reckoning inclusive) was called the nones, being therefore either the 7th or the 5th of the month. From the inaccuracy of the Roman method of reckoning the calendar came to represent the vernalequinox nearly two months after the event, and at the request of Julius Caesar, the Greek astronomer Sosigenes with the assistance of Marcus Fabius, contrived the so-called Julian calendar. The chief improvement consisted in restoring the equinox to its proper place by inserting two months between November and December, so that the year 707 (46 BC), called the year of confusion, contained fourteen months.
In the number of days the Greek computation was adopted, which made it 365.25. To dispose of the quarter of a day it was determined to intercalate a day every fourth year between the 23rd and 24th of February. This calendar continued in use among the Romans until the fall of the empire, and throughout Christendom until 1582.
By this time, owing to the cumulative error of eleven minutes, the vernalequinox really took place ten days earlier than its date in the calendar, and accordingly PopeGregory XIII issued a brief abolishing the Julian calendar in all Catholic countries, and introducing in its stead the one now in use, the Gregorian or reformed calendar. In this way began the new style, as opposed to the other or old style. Ten days were to be dropped; every hundredth year, which by the old style was to have been a leap year, was now to be a common year, the fourth excepted; and the length of the solar year was taken to be 365 days, five hours, forty-nine minutes, and twelve seconds, the difference between which and subsequent observations is immaterial. The new calendar was adopted in Spain, Portugal, and France in 1582; in Catholic Switzerland, Germany and the Netherlands in 1583; in Poland in 1586; in Hungary in 1587; in ProtestantGermany, Holland, and Denmark in 1700; in Switzerland in 1701; in England in 1752; and in Sweden, 1753.
In the English calendar of 1752, also, the 1st of January was now adopted as the beginning of the legal year, and it was customary for some time to give two dates for the period intervening between 1st January and 25th March, that of the old and that of the new year, as January 1752/3. Russia alone retained the old style, which by 1906 differed twelve days from the new.
In France, during the revolution, a new calendar was introduced by a decree of the rational Convention, on November the 24th, 1793. The time from which the new reckoning was to commence was the autumnal equinox of 1792, which fell upon the 22nd of September, when the first decree of the new republic had been promulgated. The year was made to consist of twelve months of three decades each, and, to complete the full number, five fete days, or sansculotides (in leap years six) were added to the end of the year. The seasons and months were as follows: Autumn; 22nd September to 22nd December Vendimiaire, vintage month; Brumaire, foggy month; Frimaire, sleet month. Winter; 22nd December to 22nd March: Nivose, snowy month; Plumose, rainy month; Ventose, windy month. Spring; 22nd March to 22nd June: Germinal, budmonth; Floreal, flowermonth; Prairial, meadowmonth. Summer; 22nd June to 22nd Sept.: Messidor, harvest month; Thermidor, hot month; Fructidor, fruit month. The common Christian or Gregorian calendar was re-established in France on the 1st of January, 1806, by Napoleon. Research Calendar
Grafting is an operation by which a bud or scion of an individual plant is inserted upon another individual, so as to become organically united with the stock on which it has been placed. Grafting can only take place between plants which have a certain affinity, individuals of the same species, genus, or order. The graft does not become identified with the stock to which it is united, but retains its own peculiarities of variety or species. The parts between which grafting is effected must be actively vegetating.
The advantages derived from grafting are the preservation of remarkable varieties, which could not be reproduced from seed; the more rapid multiplication of particular species, and the anticipation of the period of fructification, which may thus be advanced by several years. The principal methods of grafting are 1. By approach This process is intended to unite at one or more points two plants growing from separate roots. Plates of bark of equal size are removed, the wounds are kept together and protected from air. Stems, branches, or roots may be united in this way. 2. By scions - Under this head there are a variety of methods, such as whip, splice, cleft, saddle, crown grafting, etc.
In whip-grafting ot tongue-grafting the stock is cut obliquely across and a slit or very narrow angular incision is made in its centre downwards across the cut surface, a similar deep incision is made in the scion upwards, at a corresponding angle, and, a projecting tongue left, which being inserted in the incision in the stock, they are fastened closely together.
Splice-grafting is performed by cutting the ends of the scion and stock completely across in an oblique direction, in such a way that the sections are of the same shape, then laying the oblique surfaces together so that the one exactly fits the other, and securing them by tying or otherwise.
In cleft-grafting, the stock is cleft down, and the graft, cut in the shape of a wedge at its lower end, is inserted into the cleft; while, in saddle-grafting, the end of the stock is cut into the form of a wedge, and the base of the scion, slit up or cleft for the purpose, is affixed.
Crown-grafting or rind-grafting is performed by cutting the lower end of the scion in a sloping direction, while the head of the stock is cut over horizontally and a slit is made through the inner bark. A piece of wood, bone, ivory, or other such substance, resembling the thinned end of the scion, is inserted in the top of the slit between the alburnum and inner bark and pushed down in order to raise the bark, so that the thin end of the scion may be introduced without being bruised. The edges of the bark on each side are then brought close to the scion, and the whole is bound with matting and a lump of clay put round it.
3. By buds - This consists in transferring to another stock a plate of bark, to which one or more buds adhere. Bud-grafting is the most commonly practised, especially for multiplying fruit-trees and roses, owing to the facility with which it may be performed. Research Grafting
Agave is a genus of plants of the family Amaryllidaceae which includes the daffodil and narcissus. They are popularly known as American aloes and formerly called the century plant from the mistaken belief that it lives a hundred years before flowering, then flowers and dies. They are generally large, and have a massive tuft of fleshy leaves with a spiny apex. They live for many years - ten to seventy according to treatment - before flowering. When this takes place the tall flowering stem springs from the centre of the tuft of leaves, and grows very rapidly until it reaches a height of 15, 20, or even 40 feet, bearing towards the end a large number of flowers; then the plant apparently dies down to the ground but a lateral bud springs from the underground part of the stem and a new plant is formed. The best-known species is Agave americdna (common American aloe), introduced into Europe 1561, and now extensively grown in the warmer parts of this continent as well as in Asia (India in particular). This and other species yield various important products. The Mexicans grew the plant to form dense hedges, and removed the buds for the sugary sap which exudes from the wounds thus made. The sap was collected and fermented and distilled to form pulque, a drink resembling cider. The leaves are used for feeding cattle; the fibres of the leaves (called pita, sisal hemp, or henequen} are formed into thread, cord, and ropes; an extract from the leaves is used as a substitute for soap; slices of the withered flower-stem are used as razor-strops.

The banana is a perennialherb cultivated in tropical and sub tropical climates. Bananas are fast-growing, arising from underground rhizomes. The fleshy stalks or pseudostems formed by upright concentric layers of leaf sheaths constitute the functional trunks. The true stem begins as an underground corm which grows upwards, pushing its way out through the centre of the stalk 10 to 15 months after planting, eventually producing the terminal inflorescence which will later bear the fruit. Each stalk produces one huge flowercluster and then dies. New stalks then grow from the rhizome. The large rectangular or elliptic leaf blades are extensions of the sheaths of the pseudostem and are joined to them by fleshy, deeply grooved, short petioles. The leaves unfurl, as the plant grows, at the rate of one per week in warm weather, and extend upward and outward , becoming as much as 2.5 metres long and 0.75 metres wide. They may be entirely green, green with maroon patches, or green on the upper side and red-purple beneath. The leaf veins run from the mid-rib straight to the outer edge of the leaf. Even when the wind shreds the leaf, the veins are still able to function. Approximately 44 leaves will appear before the inflorescence. The banana inflorescence shooting out from the heart in the tip of the stem, is at first a large, long-oval, tapering, purple-clad bud. As it opens, the slim, nectar-rich, tubular, toothed, white flowers appear. They are clustered in whorled double rows along the floral stalk, each cluster covered by a thick, waxy, hood like bract, purple outside and deep red within.
The flowers occupying the first five to fifteen rows are female. As the rachis of the inflorescence continues to elongate, sterile flowers with abortive male and female parts appear, followed by normal staminate ones with abortive ovaries. The two latter flower types eventually drop in most edible bananas. The ovaries contained in the first (female) flowers grow rapidly, developing parthenocarpically into clusters of fruits, called hands. The number of hands varies with the species and variety.
The fruit (technically a berry) turns from deep green to yellow or red, and may range from ten centimetres to thirty centimetres in length and two centimetres to five centimetres in diameter. The flesh, ivory-white to yellow or salmon-yellow, may be firm, astringent, even gummy with latex when unripe, turning tender and slippery, or soft and mellow or rather dry and mealy or starchy when ripe. The flavour may be mild and sweet or slightly acid with a distinct appletone. The common cultivated types are generally seedless with just vestiges of ovules visible as brown specks. Occasionally, cross-pollination with wild types will result in a number of seeds in a normally seedless variety. Research Banana
In botany, a bract is a specialized, modified or reduced leaf with a single flower or inflorescence growing in their axil, and thus distinguished from the ordinary leaf, from the axil of which the leaf-bud proceeds. It differs from other leaves in shape or colour, and is generally situated on the peduncle near the flower. It is, sometimes called also the floral leaf. Research Bract
The Bud Moth (Spilonota ocellana) is a moth of the family Tortricidae with a wing span of between 16 and 18 mm found in the Palaearctic region and North America where it was introduced, flying from May to July. The caterpillar develops inside the sprouting buds and young shoots of deciduous trees, often causing widespread damage in orchards. Research Bud Moth
A bulb is a modified leaf-bud formed on a plant on or beneath the surface of the ground, emitting roots from its base and a stem from its centre. Research Bulb
