摘　　要：以温敏型核雄性不育系T-4及对照First为试材,花期观察花粉发芽率,测定其可溶性糖、淀粉、游离脯氨酸和蛋白质,结果期调查单果种子数,从而分析各项生理指标的相关性。结果表明:可溶性糖、淀粉、游离脯氨酸及蛋白质含量两两之间的相关性均达到了极显著水平;可溶性糖、淀粉、游离脯氨酸和蛋白质含量与果实种子数和花粉发芽率的相关均达到极显著水平;脯氨酸对花粉发芽率和果实种子数的直接通径系数都很高,分别为0.8341和0.9889。Taking T-4 and the control First as experimental material.Pollen germination percentage was calculated in anthesis and seeds per fruit was figured out also.Soluble sugar,starch,free proline and protein were tested,respectively. The aim was to research the relationships among the physiology and biochemistry characters.The results showed that the relationships among soluble sugar,starch,free proline and protein were significantly different level.And the four indexes were related to seed per fruit and pollen germination percentage significantly,respectively.The direct path coefficients of free proline was higher to pollen germination and seeds per fruit,0.8341 and 0.9889 respectively.
