บทคัดย่อ

Pollen germination of Chili cv. Khwwnuu (Capsicum frutescens L. cv. Kheenuu) cultured in liquid medium comprising 100 ppm H3BO3, 300 ppm Ca(NO3)2, 200 ppm MgSO4.7H2O and 100 ppm KNO3 was studied. The result revealed that prehydration of pollen in a humid chamber for 30 min. significantly increased the germination percentage from 7.6 to 48.0. The medium with 15% sucrose (w/v) added had the best result for pollen germination. Moreover, pollen harvested from indehiscent anther germinated better than those from dehiscent anther. Fluorescene micrograph of pollen stained with 0.2% aniline blue fluorochrome showed the callosic layer of pollen tube.
