据《园艺学报》2013年第10期《沙糖桔夏梢生长对果实糖代谢及脱落的影响》(作者黄永敬等)报道,以8年生沙糖桔为试材,研究沙糖桔夏梢生长过程中果实糖含量、糖代谢酶活性的变化以及果实脱落情况。结果表明,夏梢生长诱导果实大量脱落及抑制果实的生长,夏梢萌发生长6天后落果剧增,9天时出现落果高峰,相对落果率为7.63%/天,18天后累积落果率高达94.05%,比去除夏 According to “Journal of Horticulture” 2013 the tenth period “Shatang orange summer shoot growth on sugar metabolism and shedding effect” (the author Huangyongjing, etc.) reported that the 8-year-old Sitang orange as test material, The process of sugar content in fruit, sugar metabolism enzyme activity changes and the situation of fruit shedding. The results showed that the summer shoot growth induced a large number of fruit shedding and inhibition of fruit growth, summer shoot growth after 6 days of fruit drop sharp increase, 9 days when the peak of falling fruit, the relative drop rate of 7.63% / day, 18 days after the cumulative drop rate as high as 94.05% Than to remove the summer
