Most direct substitution of groups bound to an aromatic nucleus is limited to diazonium salts. Many groups can be added by nucleophilic substitution on a diazonium salt. 大多数连于芳核能被直接取代的基团仅限于重氮盐。许多基团可通过向得自胶的重氮盐作亲核取代而加以导入。
Fertility of cytoplasm wheat nucleus substitution lines increased with raising of the air temperature in the similar day length. 粗厚山羊草细胞质核代换系的育性在日长相近条件下,温度升高,育性提高。
The gene loci and cytoplasm effect of three multi ovary wheat ( MOW) lines were studied by monosomic chromosome analysis and nucleus substitution in this paper. 利用单体分析和多亲本常规杂交,研究了小麦多子房性状基因遗传传递规律和细胞质效应。
