1.以Tm-2~(nv)为母本的 5个杂交组合的F_1及其亲本的过氧化物酶同工酶酶谱表明,Tm-2~(nv)的酶谱图式明显地有别于5个栽培品种,F_1酶谱倾向于父本,F_2四种不同的表现型与它们各自所具有的酶谱类型之间存在着某种规律性联系。 2.Tm-2~(nv)与大叶早粉叶绿体类囊体膜的叶绿素蛋白质复合体之间无明显差异。Tm-2~(nv)叶片的黄化,不属于叶绿体突变。 3.叶绿体超微结构的研究表明,Tm-2~(nv)叶绿体中基质的含量较之大叶早粉明显增多。这个现象,是否同Tm-2~(nv)的生长缓慢有关,尚待进一步研究。
The peroxidase isoenzymes of F_1 and its parents in 5 cross combinations with Tm-2 ~ (nv) as the female showed that the pattern of Tm-2 ~ (nv) Different from the five cultivars, there was a regular relationship between the F_1 zymogram and the four different phenotypes of F_2 and their respective zymograms. There was no significant difference between the chlorophyll protein complexes of Tm-2 ~ (nv) Tm-2 ~ (nv) leaf yellowing, do not belong to chloroplast mutations. Studies on the ultrastructure of chloroplast showed that the content of matrix in chloroplast of Tm-2 ~ (nv) obviously increased compared with that of big-leaf early powder. Whether this phenomenon is related to the slow growth of Tm-2 ~ (nv) remains to be further studied.
