| 摘 要： | 用焦锑酸钾沉淀法研究了热胁迫对辣椒开花前后柱头和花柱细胞中Ca2+分布的影响。结果表明: 常温下Ca2+ 分布在柱头细胞表面、花柱引导组织细胞间隙等质外体系统中, 且在花粉管上呈先增加后减少的规律性变化; 热胁迫后, 除细胞间隙等质外体系统外, 细胞质和细胞核中也出现Ca2+, 花柱引导组织中通过的花粉管发生扭曲、变形, 这可能与Ca2+ 的异常分布有关。

| Abstract: | Calcium distribution in the stigma and style of pepper( Capsicum annuum L.cv.Xiangyan 1)under heat stress was investigated with potassium antimonite technique.The calcium precipitates emerged in the apoplast system,such as the stigma receptive surface and the intercellular spaces of the transmitting tissue in style,in which calcium precipitates firstly increased before pollen tube penetration,then decreased after that.Under heat stress,abundant calcium precipitates not only accumulated in the apoplast system,but also distributed in the cytoplasm and nucleus,and the pollen tube in the transmitting tissue showed some distortion and transfiguration.It suggests that those results may correlate with abnormalities in the distribution of calcium. |
