摘要
研究了航天搭载茄子种子SP1生物学特性。结果表明 ,航天搭载对茄子的生长发育有明显的影响 ,其变异表现在株高、生育进程、叶片大小、果实大小、结果率等方面 ,但最显著的变异是生育进程 ,从中可望选育出优良的茄子种质材料或品种。过氧化物岐化酶 (SOD)活性测定结果表明 ,变异株体内的SOD活性比非变异株或对照高出 1倍多 ,说明航天搭载可增加某些基因产物的表达量 。
The effects of the space shuttle carrying on the growth and biological characters of eggplant SP 1 population were studied.The results showed that the effect of space shuttle carrying on the growth and development of eggplant SP 1 were very significant on the characters such as the plant height, reproductive development, leaf size, fruit length, fruit quality and fruiting rate etc, especially on the plant development and the fruit size, and it is hopeful to select some good eggplant germplasm or cultivars from the population.The SOD activity showed that the SOD level in the mutant 1 plant was one time more than that in control plant, indicating that the space shuttle carrying may increase the expression of some genes and lead to the great change in morphological characters.
