摘 要: 以“早蜜橙”这个新发现的柑桔嫁接嵌合体及与其有关品种类型的柑桔为材料,通过叶片气孔观察、花粉试验、多种酶同工酶分析和果实性状的比较分析,研究了它的来源、结构和果实主要经济性状的表现.结果发现:(1)在来源上,“早蜜橙”是由甜橙(新会甜橙的可能性最大)和南丰蜜桔形成的嫁接嵌合体.(2)在嵌合体结构上,“早蜜橙”是一个不完全周缘嵌合体,LI、LII以橙为主,LI则以桔为主,兼有橙因子.(3)“早蜜橙”果实品质上等,果实性状大部分来自橙,少数来自桔.糖、酸等主要营养物质的含量大都介于两亲本之间,绝大部分水解氨基酸含量比原接穗和砧木品种都高,有较大的利用价值. With “Zaomi Orange”-the new citrus graft chimera and related cultivars types as material,a series of experiments including the observation of the leaf stomata,pollen test,analysis of zymograms as well as the analysis and comparison of fruit characters was performmed. The results indicated that:(1)“Zaomi Orange” was a graft chimera the stock being Xinhui Sweet Orange (most probable),and the scion NanfengSweet Mandarin. (2)“Zaomi Orange” was an incomplete mericlinal chimera. Orange was dominant in LII and LIII,and in LI mandarin prevailed over or ange. (3)Most of the fruit characters of “Zaomi Orange” was derived from orange, the contents of most of the nutrients such as sugar,acid were between the two parents,while the contents of most hydrolytic amino acids were higher than the stock and scion,demonstrating that “Zaomi Orange” was a valuable chimera.
