结球甘蓝不同初级三体的花粉整齐度及生活力的研究

Comparison of Pollen Regularity and Activity of One Anther of Primary Trisomic Lines

以"中甘11"结球甘蓝初级三体为试材,结球甘蓝二倍体为对照,研究比较了其花粉生活力、花粉整齐度和花粉量。结果表明:结球甘蓝各初级三体花粉的花粉量、整齐度、生活力均低于二倍体,但不同三体之间存在着显著差异。经比较发现,三体6的花粉不管是在花粉量、花粉整齐度还是花粉生活力上与二倍体相比都达到了差异极显著水平,说明结球甘蓝第6染色体对花粉各方面的影响都较大,可能存在于花粉发育相关的基因。

Taking cabbage ＇Zhonggan 11＇ primary trisomic lines as test material,diploid line cabbage as control,the pollen amounts,regularity and activity of one anther of every trisomic lines were studied.The results showed that the viability,regularity and density of the pollen in the trisomics were lower than that of the diploid,but the difference among the different trisomics was existed obviously.The viability,regularity and density of the Tri-6 pollen were compared with diploid reached extremely significant difference level.It showed than the chromosome-6 may exist in the genes related to pollen development.
