Description The present study is on the growth and development and effect of different growth regulators on physico-chemical characters and fruit drop pattern were carried out with some minor fruit of West Bengal viz. rose apple, water apple (white and pink type), carambola (sweet and sour type) and chalta. The fruit growth of rose apple in terms of fruit weight, volume, length and diameter followed simple sigmoid curve. During Phase I, the growth of fruit was slow upto 40 days after fruit set. In phase II was the raid growth phase upto 70 days after fruit set and phase III was the final phase which commenced from 70 days after fruit set to 80 days after fruit set. Growth of water apple (white and pink type fruit followed a single signoid curve. The fruit weight, volume, length and diameter gradually increased with the age of fruit and reached their maximum value at 45 days after fruit set. The maximum change in fruit weight, volume, length and diameter of water apple (white type) occured between 30 to 40 days after fruit set. While ascorbic acid content of water apple (pink type) fruits increased as the fruit approached to maturity. TSS/acid and sugar/acid rato of fruits increased with the progress of fruit maturity. The fruit growth of ambola (sweet and sour type) in terms fruit weight, volume, length and diameter at initial stage was comparatively slower while it grew at a faster rate at 30 days after fruit set and it was maximum at maturity i.e. 50 days after fruit set. It was also observed that initially, the volume of fruit was uniform with that of weight of fruit but he later stages, the volume was more than the weight. The ascorbic acid content of fruit recorded an irregular trend upto 30 days after fruit set then increased through out the fruit growth and development. TSS/acid and sugar/acid ratio increased gradually from 10 days after fruit set to fruit maturity. During the course of investigation it was found that the total sugar increased with the fruit development and maturityand reached maximum at 160 days after fruit set. Reducing sugar content increased from 20 days after fruit set to 40 days after fruit set, the declined at 60 days after fruit set and finally followed an increasing trent from 80 days after fruit set to harvest maturity. The fruit drop of rose apple, water apple (white and pink type) and carambola (sweet and sour type) was minimum at initial stage. It increased with the advancement of growth. The result revealed that application of growth substances showed marked beneficial effect of retention of fruits. Among the different growth substances, GA3 20 ppm in general proved very effective in reducing the drop of immature fruits, followed by NAA. Control fruits showed the maximum fruit drop. The chemical constitutes like TSS, total sugar and reducing sugar was maximum in GA320 ppm. The tritable acidity was minimum in all the fruits treated with GA3 at 20 ppm. Maximum ascorbic acid content of fruits was recorded by the application GA3 at 20 ppm in the fruits. Growth regulators also improved the chemical characters of fruits as compared to control.
