“…Studies of the effect of gibber ellin preparations showed that under long-day conditions they induce stem and flower formation in unvernalized one-year-old seedlings of biennial spe cies-henbane, carrot, parsley, turnip, chicory, cabbage, and European gold enrod (Solidago virga-aurea)-as well as in seedlings of winter forms Arabidopsis thaliana, rape, and lettuce (21,33,79,106,198). In contrast to them the treatment of winter forms of cereals-rye, wheat, and barley with gibberellins resulted only in the formation and growth of stems and in the slight stimulation of the development of rudimentary spikes but did not induce heading and flowering of these plants (23,33,106,122,152).…”

CHAILAKHYAN Timiryazev Institute of Plant Physiology, Academy of Sciences, MoscowThe individual development or the ontogenesis of plants, which begins with the ovary's fertilization or with formation of an embryonic bud and ends with death, comprises the whole cycle of the plant's life and includes all its life processes. The transition of plants from vegetative growth to flowering, when new progeny develops in tissues of the maternal plant, is the most essential period in ontogenesis. The physiological nature of the transformations which precede and condition the formation and develop ment of floral organs is the main subject of this paper.The morphological picture of flower development, outlined in the theory of metamorphosis by the great poet and botanist Goethe, who thought of a flower as a transformed leaf shoot, is now widely recognized and has been developed by numerous scientists (182). The physiology of processes which precede the development of a flower has not been studied as well; the pic ture is vague and contradictory though the earliest conj ectures go back as far as the second half of the last century. And if anybody were asked to name a phenomenon of plant life where the gap between morphology and physiology is the widest, he would certainly indicate flowering.Sachs's hypothesis (162) on plant-forming and especially on flower-form ing substances, which was first published in 1880, was the earliest concept of the physiological nature of plant flowering. Klebs's theory (95) of the role of the ratio of nutrients appeared much later (in 1918). A new phase in the study of the physiological nature of the flowering phenomenon began immediately. In 1918, Gassner (70) found that winter forms require cold and that they differ in this requirement from spring forms; he discovered the phenomenon of thermo induction in plants while in 1920 Garner & Al lard (69) discovered photoperiodism in plants.During the half century that has passed since that time, the physiology of flowering became enriched with new basic data and with essential theo retical conclusions. These findings have been reviewed in articles regularly published in the Annual Review of Plant Physiology (56,62, lOS,112,116,165,172), in detailed reviews published in the Encyclopedia of Plant Phys iology, Volume 16 (119,139,140,153), as well as in other articles and books (34,76,86,107,166,197,204). The present state of the problem has been fundamentally outlined by Lang (109) An answer to the first question can be found in the realm of phenomena where both genetic factors and plant reactions to environmental conditions play a decisive role. Under common natural conditions,fiowering of seed plants takes place after the formation of vegetative organs or, more pre cisely, after they have passed the young age or juvenile stage. The duration of the juvenile period in many plants dep...

“…Salisbury also points out that stage 2. clearly the beginning of a receptacle structure, can undergo reversion to vegetative growth (11). Receptacle development in these short-day plants thus may parallel preflowering stalk developnment in certain long-day plants such as spinach (8) andl Centaurium minius (1) Donor-Receptor Systenz. Experiments were aimed at defining ithe conditions that produce consistently the strongest flowering response from a single dark induction under standard conditions.…”

“…Lang discovered that this requirement could also be eliminated by gibberellin (44). However, this is not invariably the case, since overwintering grains and other plants have not yet responded satisfactorily (44, 57); a light requirement may still have to be met (58), and the flower response may be abnormal when it occurs (59). Wittwer and Bukovac have pointed out that there still seems to be a specific temperature limit, although it may be raised by gibberellin treatment (45,60).…”

In the twenty-odd years since the potentialities of the auxins were first widely recognized, no plant hormones have excited as much botanical and horticultural interest as have the gibberellins. These compounds strikingly stimulate the growth of many plants, promote flowering in some cases, and cause a variety of other interesting morphological and physiological responses. Their use opens up new avenues of approach to botanical problems, and many of their effects promise to be of economic importance in agriculture and horticulture. In this brief introduction to the work being carried on with the gibberellins no attempt has been made to completely cover the rapidly growing literature; papers have been cited only as they seemed especially pertinent. A comprehensive review through 1956 is available (1), recent summaries have been published by the British workers (2, 3), and some manufacturers of gibberellins have prepared useful bibliographies which include recommended methods of treatment (4). Wittwer and Bukovac have evaluated in detail the implications of this development for agriculture and horticulture (5).
