本文报道了美国佛罗里达州尚在鉴定的44种柑桔砧木对植株生长、产量和果实品质的影响。材料和方法第一项试验包括无病毒的珠心胚伏令夏橙和马叙葡萄柚,分别嫁接在18种砧木上。1968年定植,采用完全随机区组设计,4株为一小区,重复3次。栽距为10×15英尺(即290株/公顷)。试验用砧木是从有矮化表现的砧木以及尚未测试的实生苗中选出的。
This article reports the effects of 44 citrus rootstocks identified in Florida, USA, on plant growth, yield and fruit quality. MATERIALS AND METHODS The first experiment included the virus-free bead-core embryo valerian summer orange and Marcella grapefruit grafted onto 18 rootstocks. 1968 colonization, using a completely randomized block design, 4 for a small area, repeated 3 times. Planting distance is 10 x 15 ft (ie 290 plants / ha). Rootstocks for testing are selected from rootstocks with dwarf performance and virgin seedlings that have not been tested.
