【摘要】 本文以长富2号×新疆红肉苹果等6个杂交组合的杂种实生苗为试材,对苹果红叶基因的多效性进行了研究,结果表明,苹果叶片红色性状对非红色性状表现为显性,杂交群体中,具有红叶性状的实生苗数量明显少于非红叶性状实生苗数量,偏离孟德尔分离规律,组合间差异明显,红叶实生苗平均比例为23%-44%;红叶基因对水分调节相关基因、耐盐相关基因具有负调控作用,对根系发育相关基因亦有一定影响,促进主干根生长,抑制侧根发生。更多还原

【Abstract】 The seedlings of 6 hybrid combinations between Naganofuji 2 and Red flesh apple cultivars were used to analyze red leaves genetic multiple-effects of apples.The result showed that red leaf color of apples was dominant to non-red leaf color, Hybrid combination progenies had remarkable difference which mean ration of red leaf seedlings was 22%～44%fewer than that of non-red leaf color of deviating mendelian segregations.The red leaf gene(RLG) played an negtive role in the water regulation gene,the salt tolerance gene and the disease resistance gene,but RLG was important for seedling root development, including in promoting elongation of the primary roots and inhibiting the initiation of lateral roots.更多还原
