我所1983—1985年的品比试验结果表明,早熟无核葡萄比武汉地区目前主栽的优良品种白香蕉稳产、早熟、质优、抗病。 三年试验表明,早熟无核葡萄平均株产比白香蕉高0.2斤,1985年的平均株产量比后者接近高一倍(表1)。从表l可以看出,无核葡萄挂果后的产量稳定,并逐年上升,而白香蕉的产量不够稳定,有大小年之分。我所几年来观察结果表明,无核葡萄从萌芽至浆果成熟约需91—105天,从开花至浆果成熟期约需45—49天,6月下旬成熟,比白香蕉早25—28天(表2)。此外,该品种需10℃以上活动积温为2076.6℃,比白香蕉低716.8℃。无核葡萄树势中等,果枝着生在母枝第5—7节,每
Our 1983-1985 product ratio test results show that the early maturing non-nuclear grapes than the current varieties of Wuhan main varieties of white bananas stable, early maturity, high quality, disease resistance. Three years of testing showed that the average yield of precocious seedless grapes was 0.2 kg higher than that of white bananas and the average yield of plants in 1985 nearly doubled the latter (Table 1). As can be seen from Table l, the yield of seedless grape fruit is stable and increases year by year, while the yield of white banana is not stable enough, with the size of year. Our observations over the past few years show that seedless grapes need about 91-105 days to germinate from ripening to berry ripening, which takes about 45-49 days from flowering to berry ripening, ripening in late June and 25-28 days earlier than white banana Table 2). In addition, the species need to be above 10 ℃ active accumulated temperature of 2076.6 ℃, 716.8 ℃ lower than white banana. Seedless grape trees are medium-sized, fruiting branches are born in mother branches 5-7, each
