Abstract : GA at 0 and 30 p.p.m., BA at 25 and 50 p.p.m. and/or Ca at 0.1 and 2% was applied on 30 Jan. and again on 1 Mar. 1984 and 1985 (off and on years, respectively) to the alternate bearing cultivar Langra. In 1984, the length of terminal shoots was greatest in the treatment with GA, and, in 1985, it was greatest with 30 p.p.m. GA + 50 p.p.m. BA. The number of lateral shoots was not affected by the treatments. Data are tabulated on the number of leaves/shoot, leaf area/shoot, panicle length, flowering characteristics, number of flowers/panicle, and % of hermaphrodite flowers/panicle. In 1984, panicle length was greatest (26.6 cm) when all 3 chemicals (combined) were applied at the highest rate. Applying 50 p.p.m. BA + 2% Ca gave the highest percentage of hermaphrodite flowers/panicle (70.5%) in 1984.
