对水稻雄性不育的生物化学研究,国内外已有不少报道,但一般集中在对花药(粉)的研究上。对不同育性营养体的生化特性的研究则报告甚少。Peterson等对不同育性的玉米苗期营养体的β-淀粉酶进行了研究,发现他们所研究的9个组合中,玉米保持系的β-淀粉酶有比不育系高的趋势,由此认为,β-淀粉酶可以作为苗期鉴定玉米育性的生理指标。在水稻上则有关于保持系和不育系营养体的光呼吸、RNA含量等方面的研究。但通过大量品种的研究来分析不同育性植株在营养时期的某些生化特性及其遗传控制者还不多。本工作的目的,是通过对不育系、保持系、杂种一代幼苗β-淀粉酶活性的比较,
Biochemical research on male sterility in rice has been reported at home and abroad, but generally focused on anther (powder) research. Research on the biochemical properties of different fertility nutriments is poorly reported. Peterson et al. Studied β-amylase in maize seedling vegetative organs with different fertility and found that maize maintainer β-amylase tended to have a higher tendency than male-sterile lines in the nine combinations studied It is considered that β-amylase can be used as physiological index to identify maize fertility at seedling stage. In rice, there are studies on light respiration and RNA content in nutrient lines of maintainer lines and sterile lines. However, there are not many biochemical characteristics and genetic control of different fertility plants during the nutritional stage through a large number of species. The purpose of this work is to compare the β-amylase activity of CMS, maintainer and hybrid seedlings,
