Ong S. H., . and Yeang H. Y., . and Mohd. Napi bin Daud, . Influence of meteorological factors around the time of hand-pollination on Hevea fruit-set. pp. 167-175. ISSN 0127-7065
Abstract
Stepwise multiple regression analysis of the 1975 cross PB 5/51 RRIM 703 showed fruit-set success to be negatively correlated with evaporation on the day of hand-pollination and positively correlated with maximum temperature; also with maximum temperature two days after pollination and relative humidity the day before. The influences of evaporation and relative humidity on fruit-setting were confirmed using a non-parametric procedure of analysis involving twenty-two crosses carried out over five years. Evaporation was also associated with the disparity in fruit-set success between the annual main and secondary flowering seasons. However a causal relationship has not been ascertained in this instance.
