Abstract

The objective of the research was to determine the effect of pre harvest CaCI2 application on quality changes of tomato fruits. Experiment consisted of 5 treatments: control, application of 0.1 M CaCI2 at 18 ± 2 days after anthesis (DAA), 0.1 M CaCI2 at 25 ± 2 DAA, 0.2 M CaCI2 at 18.t2 DAA and 0:2 M CaCI2 at 25 ± 2 DAA. Tomato fruits cv. Ratna harvested at breaker stage were used throughout the experiment. Variables to be observed were peel color, weight loss, fruit firmness. total soluble solids, titratable acidity, and respiration. Result of the experiment showed that application , of CaCl2 could not maintain quality and extend shelf life. Application of 0.1 M CaCl2 at 25 ± 2 DAA inhibited peel color. development at  9. 12, and 21 days after harvest.   Key words: Pre harvest, CaCI2, Tomato, Storage

Abstract

Information on the pattern of fruit drop of mango is required to determine the appropriate method and time in reducing fruit drop. By this methodf, fruit retention or number of harvested fruit of mango can be increased.The aim of this research was to determine the pattern of fruit drop of Gadung 21, Manalagi 69 and Golek 3 I . The results of this researchs howedt hat the pattern of fruit drop of Gadung2 1, Golek 31 and Manalagi 69 was similar. All cultivars I showed that there was one peak (the highest number of fruit drop) in fruit drop. It occurred at 6 days after anthesis (DAA). After 24 DAA, the number offruit drop was constant, namely near to zero. It occurred until harvest.Key words: Mango, Fruit drop, Fruit set
