High Temperature Has Negative Impact on Pollen Development in Chili Pepper (Capsicum annuum L.) cv. Tanjung-2
The development of male reproductive organ in plants is seriously affected by the adverse abiotic stresses. In this study, we investigated pollen development, particularly at microsporogenesis and micro gametogenesis stages of chili pepper (Capsicum annuum) cv. Tanjung-2 upon exposure with high temp...

The development of male reproductive organ in plants is seriously affected by the adverse abiotic stresses. In this study, we investigated pollen development, particularly at microsporogenesis and micro gametogenesis stages of chili pepper (Capsicum annuum) cv. Tanjung-2 upon exposure with high temperature (day/night = 36/33°C). For this objective, anther of different flower sizes ranging from <2.5 mm; 34.5 mm; 4.57 mm; to 711 mm from treated and non-treated plants were collected. The results revealed that the early microsporogenesis stage was highly sensitive to high temperature indicated by a low progression of cells into subsequent process in meiotic division.
