Extraction of Gibberellin for Use in Hybrid Rice Production

The gibberellins are one of the major groups of growth-promoting hormones, which play an essential role in regulation of growth and development of angiospermic plants. GAs used at parts per million levels result in a number of physicological effects such as elimination of dormancy in seeds, acceleration of seed germination, improvement in crop yield, marked stem elongation, promotion of fruits setting, induction of flowering in photoperiodically sensitive and cold-requiring plants and in overcoming dwarfism. Despite its commercial importance, limited options are available with the growers to use gibberellins for different purposes, these are highly expensive and are not produced in India. The scientists of the Division of Plant pathology have identified potential strains of Gibberella fujikuroi for the production of gibberellins, which is easy to isolate in large quantity. In comparison to other gibberellins, which are presently available in market, this product is cheaper also because they have used low priced carbon source for culturing of Gibberella fujikuroi strains.

Application

The crude gibberellin extract is suitable for the elongation of second leaf shealth for hybrid rice production.
