Abstract : Studies were made of several vegetative and reproductive growth parameters in normal and malformed buds, shoots and panicles of the cultivars Amrapali, Dashehari, Langra and Mallika. Leaf area was significantly less in trees with floral malformation, as were the length of 30-day-old panicles, number of developed nodes/panicle, and length of internodes of the primary and secondary rachis; however, the numbers of shootlets and panicles that developed/apical zone were greater in malformation-affected trees. Hermaphrodite flower numbers/panicle and pollen viability were not affected. Less nitrate reductase activity, lower N and soluble sugar contents, and enhanced contents of starch, auxins, gibberellins and abscisic acid were also observed in malformed buds and panicles.
