猕猴桃海沃德芽变新品系“93-01”的生物学特性

对海沃德及其芽变新品系“93- 0 1”三年生高接树进行了观察研究 ,结果表明 :93- 0 1芽变新品系不仅在新梢茸毛及颜色、混合芽体大小、果实形状等形态特征上与海沃德品种完全不同 ,而且各器官生长物候期均相应提前 ,尤其是开花物候期比海沃德提早 3～ 4d,克服了海沃德品种与配套雄株——陶木里花期不完全相遇的缺点 ,从而显著提高了授粉受精机会 ,提高了座果率 ,果实生长快 ,明显提高了品种的丰产性

Evaluation of the New Clone Mutated from Kiwi Fruit Hayward

The new clone"93 01”was a natural mutant found in kiwi fruit (Actinidia deliciosa cv.) Hayward .By observed for several years,the budding and leaf spreading of "93 01”were three to four days earlier,and the beginning of spout growth was three days earlier,and flowering was three to four days earlier than those of its stock plant,Hayward. It was significant that the bloom of the new clone became full matting one with pollinating cultivar Tomuri,resulting in the increase of fruit setting by 24%.The main economic characters of "93 01”,such as fruiting,per fruit weight,quality and flavor,were better than those of Hayward.
