ABSTRACT

Need for food and medicines is supposed to continue due to ever-growing world population. Investing in agriculture is the solution to reducing poverty and hunger in developing countries. Keeping that in mind present investigation was made to evaluate effect of plant growth regulators (PGRs) on morphology of Fagopyrum esculentum. Results revealed that IAA +BAP (100 mg l -1 ) concentration was effective in enhancing number of leaves, stem diameter, number of inflorescence as well as seed yield. Number of leaves reduced in 100 mg l -1 of GAs, ABA, ABA+GAs and 25mg l -1 ABA treatments. Reduction in stem diameter (GA S 25 and 100 mg l -1 ), number of inflorescence (ABA 25 mg l -1 ) and seed yield (IAA+ABA 50 mg l -1 ) was recorded. BAP alone as well as with ABA (ABA+BAP) and IAA (IAA+BAP) at 100 mg l -1 concentration showed significant increase in number of branches however lower concentration of ABA+GA S and BAP+GAs reduced it. Leaf surface area was enhanced with 100 mg l -1 concentration of BAP and BAP+GAs and declined with 25 mg l -1 concentration of ABA, GAs, ABA+GAs and higher concentration (50, 100 mg l -1 ) of IAA+ABA.
