摘　　要：通过对15种石斛花粉生活力测定及人工辅助自交授粉和杂交授粉试验,结果表明：石斛种间的花粉生活力差异较大,介于38.0% ～79.3% 之间;不同种石斛自交或种间杂交的结实率差异较大,自交结实率在0～73.3%,杂交结实率在0～86%.石斛花粉生活力与结实率无明显相关性.Pollen vitalities of 15 species of Dendrobium were determined.The fruit-bearing rate of the orchids affected by the artificially induced self-or cross-pollination was investigated.The results showed that the pollen vitalities of the species varied from 38%to 79.3%.The fruit-bearing rate ranged 0-73.3% by self-pollination,and0-86% by cross-pollination.There was no significant correlation found between the pollen vitality and fruit-bearing among the various species.
