脐橙生长地区甚至日本南部,由于冷的环境经常表现异常落果。花期应用油菜素内脂处理‘森田’脐橙的花。处理后50天观察到0.01ppm油菜素内脂处理树座果率分别增加约2.5到5倍。对夏季处理之前置于露天比在塑料大棚下的树对油菜素内脂表现较大反映。花后两个月处理也有较高的座果率。处理和未处理树之间果实品质无差异。 Navel orange growing areas and even southern Japan, often show abnormal results due to cold conditions. Flowering Brassica oleracea leaves ’Morita’ navel orange flower. At 50 days after treatment, 0.01 ppm brassinolipid treatment tree fruit rate was observed to increase by about 2.5 to 5 times, respectively. The response to the tree-to-brassinolipid in the open air before the summer treatment was more pronounced than in the plastic greenhouse. Two months after flowering also had a higher fruit set rate. No difference in fruit quality between treated and untreated trees.
