用天然生长调节物质月光花素处理徐薯１８的研究结果表明，经０．１活性单位月光花素处理，甘薯插枝发根量增加１培多，根系活力明显增强；植株生长快，叶面积增加２０％—６０％，高叶面积时期从１个月延长到２个月，因而有效光合叶面积和光合时间明显增加．合理施用月光花素，可使幼薯分化提早１０天，薯数增加１８％，薯块肥大加速，约可提前２０天成熟，甘薯产量平均可提高１４％，相当于每公顷净增鲜薯４５００ｋｇ，作者在文中还比较了在甘薯生长的不同发育时期，用不同方法施用不同浓度的月光花素，对甘薯生长发育的影响。
The results of the study on the treatment of XUHU 18 by the natural growth regulator moonflower anthocyanin showed that the root activity of sweet potato cuttings increased by 1percent and the root activity increased obviously after treated by 0.1 activity unit of moonflower. The plant growth was fast and the leaf area Increased by 20% -60%, the period of high leaf area increased from 1 month to 2 months, so the effective photosynthetic leaf area and photosynthetic time increased obviously. Reasonable use of moonlight flower, can make potato differentiation 10 days earlier, the potato number increased 18%, tuber fertilizer hypertrophy accelerated, about 20 days ahead of maturity, the average sweet potato yield increased by 14%, equivalent to a net increase of fresh potato per hectare 4500kg , The author also compared the different growth stages of sweet potato in the text, using different methods of different concentrations of lunar anthocyanidin on the growth and development of sweet potato.
