PHYSIOLOGICAL EFFECTS OF SEED TREATMENTS WITH GA ON SEEDING GROWTH UNDER LABORATORY AND FIELD CONDITIONS IN JOWAR

Sakdeo Babita Marutirao

Abstract :

Immersion of seeds in solutions containing PGRs has been suggested by various workers to enhance seed germination and emergence potential, under adverse growing or environmental conditions, or alternatively under satisfactory conditions using seeds of impaired germinating quality. GA are used to increase alpha amylase activity in germinating Barley seeds . which is used for malt production in beer Industry. This hormone also stimulates hydrolysis and transport of stored food material from endosperm and cotyledons to the growing Root–Shoot axis specially in the cereals. Interest in the use of growth regulators in crop production arises from the beliefs of plant physiologists that maximum levels of plant productivity GA promote seed germination .GA has several form .GA 10–1, GA 10–2, GA 10–3…..so on . All the Gibberellins are able to promote either stem elongation or cell division although their relative effectiveness may be different. Studied for determining effect of different concentration of GA in Jowar on percentage germination and seedling growth in terms of shoot and root lengths and dry weight distribution. Under Laboratory and Field conditions.
