在泰国北部,研究了喷施不同浓度丁酰肼(SADH)和马来酰肼(MH)(1000,4000和7000ppm)和喷施次数(1—3次)对不同园地龙眼树(栽培种“Chom—Pu”)营养生长的影响。结果发现;老茎节间的直径,老复叶长度,新茎节间直径,新枝长度和新复叶长度不受园地位置的影响,而叶萌发,老枝长度和新老小叶长度则受影响。老茎节间直径和老枝、老小叶、新枝、新复叶、新小叶的长度都不受 sADH 和 MH 的影响。在干旱的2号园地里,MH 延缓叶的萌发,喷过两次 MH 的新茎节间直径小于只喷一次的。相反,在潮湿多雨的1号园地里,与未处理相比,SADH 和 MH 增加老复叶的长度。因此,MH 的浓度和喷施次数之间存在相互影响。
In northern Thailand, we studied the effects of spraying different concentrations of butyrylhydrazide (SADH) and maleic hydrazide (MH) (1000, 4000 and 7000 ppm) and spraying times (1-3 times) “Chom-Pu”) Effect of vegetative growth. The results showed that the diameter of the old stem, the length of the old compound leaf, the diameter of the new stem, the length of the new branch and the length of the new compound leaf were not influenced by the position of the garden, but the length of the leaf germination, the length of the old branch and the length of the new leaf were affected . The diameter of the old internode and the old branches, old lobules, new branches, new compound leaves, the length of new leaflets are not affected by sADH and MH. In the arid No.2 field, MH delayed the germination of leaves, and the diameter of new internodes sprayed twice was less than that of spray once. In contrast, SADH and MH increased the length of old compound leaves in wet and rainy No.1. Therefore, there is an interaction between the concentration of MH and the number of sprays.
