Abstract

All possible crosses among 5 strains of Gossypium hirsutum were made, and the pollen tubes were grown in vivo for 4 h before being fixed, stained and measured. Temperatures ranging from 18.5 to 40.0 °C were tested for pollen germination and pollen tube growth. The optimal temperature for pollen tube growth was 30.0 °C. Relative humidity levels of 0 to 100% were used as a pre-pollination treatment of the pollen. Significant differences among the mean pollen tube length of the strains occurred due to pollenXstyle interactions. The strains also differed in the number of styles which did not support pollen tube growth. These differences were also due to pollenXstyle interactions. Pollen and style strains could be ranked according to their relative contribution to pollen tube length.

摘要

所有可能的棉花（Gossypium hirsutum）5 个品种的杂交都进行了，花粉管在固定、染色和测量前在体内生长了 4 小时。测试了从 18.5 到 40.0°C 的温度范围以用于花粉萌发和花粉管生长。花粉管生长的最佳温度为 30.0°C。花粉作为授粉前处理，使用了 0 到 100%的相对湿度水平。由于花粉 X 花柱相互作用，品种间的花粉管平均长度存在显著差异。不同品种的花柱数量也不同，这些花柱不支持花粉管生长。这些差异也是由于花粉 X 花柱相互作用造成的。可以根据花粉和花柱品种对花粉管长度的相对贡献对其进行排序。
