Flowers removal: Its effect on reproductive structures abortion and yield in pepper (Capsicum annumm L) at low temperatures

Abstract:

In C. annuum the relationship between the number of fruits and abortion percentage of following reproductive structures have been reported. This shows the complexity to maintain relative high yield in C. annuum. The main objective of this work was to evaluate the effect of flower removal intensities on fruit production and fruit size under greenhouse conditions. Four intensities of flower removal were evaluated (without deflowering, flower removal at first, second and third node). A block design with four replications was employed. Maximum of fruit production were delayed with higher flower removal. Higher yield (P<0.05) and number of fruits between 200 and 300 g were obtained with flowers removal at first node. Higher removal of flowers number was related to lower fruit size.
