bolting by gibberellic acid

(Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences, China)All material on this site has been provided by the respective publishers and authors. F. V. (hVEi'; l . Gibberellins have little or no effect on root growth. Plants bolting after GA~ application deviated mostly from normal bolters by the formation of a short thickened stem, but started flowering only occasional- ly. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. Please note that corrections may take a couple of weeks to filter through Certain light sensitive seeds e.g., lettuce and tobacco show poor germination in dark. It may either have no effect, or inhibit, or may activate flowering. Strik­ing growth rates of as much as 25 cms. The plant itself produces large quantity of gibberellin atilt is time.----- Gibberellic acid is a hormone found in plants. It is considered that in such dwarf plants (i) the gene for producing gibberellin is missing, or (ii) the concentration of the natural inhibitors is higher. Gibberellic acid has been used for several decades in agriculture to … 0[, T958 .

per day have been observed in rice plants under field conditions. (Partial submergence of rice plants is believed to reduce partial pressure of OIn many herbaceous plants the early period of growth shows rosette-habit with short stem and cauline leaves. Generally affects only the plant parts above the soil surface. ABBREVIATIONS GA3 = gibberellic acid; LD = long day. Gibberellic acid, also called Gibberellin A3, GA, or GA 3, is a very potent hormone whose natural occurrence in plants controls their development. In Hyoscyamus niger (also a Long Day Plant) gibberellin treatment causes bolting and flowering under non-inductive short days. It is common observation that the dark grown plants become etiolated and have taller, thinner and pale stems while the light grown plants have shorter, thicker and green stems, and it may be concluded that light has inhibitory effect on stem elongation. In such cases the protein content of the stem falls while soluble nitrogen content increases prob­ably due to more breakdowns of proteins than their synthesis. You can help correct errors and omissions. Gaskill (1) 2 .

has shown that gibberellic acid can be used to replace a considerable portion of the thermal induction required for … Most pronounced effect of gibberellins on the plant growth is the elongation of the internodes, so much so that in many plants such as dwarf pea, dwarf maize etc., they overcome the genetic dwarfism. Germination of the pollen grains is stimulated by gibberellins, likewise the growth of the fruit and the formation of parthenocarpic fruits can be induced by gibberellin treatment. While in Long Day Plants the gibberellin treatment usually results in early flowering, its effects are quite variable in Short Day Plants. You can help adding them by using Deepwater rice (Oryza sativa) is another notable example of pronounced effect of gibberellins on elongation of internodes so that its foliage may remain above water in the field. Germination starts vigorously if these seeds are exposed to light or red light. Rudbeckia speciosa (It is a Long Day Plant) by the application of gibberellin even under non-inductive short days. This requirement of light is overcome if the seeds are treated with gibberellic acid in dark.

It is considered that the light in some way lowers the level of endogenous gibberellins and inhibits the stem growth. Treatment of light grown plants with gibberellin also stimulates the stem growth and they appear to be dark brown. But, when treated with gibberellin the internodes elongate markedly and they look like tall plants. STOL rAND .

Since GA regulates growth, applications of very low concentrations can have a profound effect while too much will have the opposite effect.
