作者研究了哈姆林甜橙(Citrus sinensis(L.)Osbeck)在美国佛罗里达州南部三十个砧木品种上的存活率、抗病性、产量及果实品质等性状的表现,筛选出7个生长旺盛、产量高、品质好、适合当地土壤、气候条件,并对衰退病(Tristeza)有抗性的砧木。 各组合植株于1978年春嫁接、接穗为注册的无毒哈姆林甜橙,1979年2月定植于田间,定植后8年检查,发现哈姆林甜橙在各砧木上的存活率有很大差异:以F80-18枳柚砧为最好,存活率达100％;施文格枳柚及FF1-131-20杂种砧分别死亡1株和2株;而马蜂橙(C.hystrix)砧植株,定植后18
The authors studied the performance of citrus sinensis (L.) Osbeck on the survival of 30 rootstocks in southern Florida, disease resistance, yield and fruit quality traits, screening out 7 growth Strong, high yield, good quality, rootstock suitable for local soil, climatic conditions and resistant to Tristeza. All combinations of plants were grafted in the spring of 1978 with scion as registered non-toxic Hamlin orange, colonized in the field in February 1979 and inspected eight years after colonization. The results showed that there was a large survival rate of Hamlin orange on each rootstock Differences: F80-18 orange anise best, the survival rate of 100%; Shiwengeng citrus and FF1-131-20 hybrid anvil were killed 1 and 2 strains; and the bee orange (C. hystrix) anvil plant, After planting 18
