朋娜等脐橙品种在不同砧上的高换试验

Experiments of Grafting Highly on Different Stocks

朋娜、纽荷尔、纳维林娜等良种脐橙分别在枳砧锦橙、红桔砧、实生甜橙上进行高接,对其嫁接亲和性、生长势、座果情况等进行调查分析。结果表明朋娜与枳砧、红桔砧和实生甜橙嫁接亲和力均高,树冠恢复快,树势中庸、果大、丰产、商品性好。纽荷尔在枳砧锦橙上高接,综合性状好,而在红桔砧上高接树势旺长,座果率虽高,但果实小,商品率低,成熟期推迟。纳维林娜在实生甜橙上高接综合性状好,树势中庸、果大、丰产、商品性好。脐橙奉园72—1属晚熟品种,在红桔砧上高换,综合性状较好。

Improved orange varieties such as Skaggs Bonanza navel orange,Newhall navel or- ange,and Navelina navel orange were highly grafted on the stocks of trifoliate orange,Jinchen orange,red tangerine and sweet orange seedlings respectively.The affinity,growing status,and fruiting rate were studied and analyzed.Our results have shown that the affinity was high when Skaggs Bonanza navel orange was grafted on the stocks of Jinehen orange,red tangerine and sweet orange seedlings,their crown recovered quickly,the fruits were big and yield highly. When Newhall navel orange was grafted on the stocks of Jinchen orange,all the properties were satisfying;when grafted on red tangerine,the crowns grew wildly,the fruiting rate was high but with less fruit,and the mature period was prolonged.When Navelina navel orange was grafted on stocks of sweet orange seedlings,all the properties were satisfying,fruits were big and yield- ed highly.Navel orange“Fengyuan 72—1”was a late variety,its properties were satisfying when grafted on stocks of red tangerine.
