Abstract
For exploring agronomic measures to solve the problem of drought at seedling stage of sweetpotato,effects of uniconazole,mepiquat chloride and rooting powder on sweetpotato roots morphology,endogenous hormone mass fraction,physiological and biochemical indexes under simulated drought stress were studied.The results showed that uniconazole treatment and mepiquat chloride treatment all significantly decreased root length and root surface area of all sweetpotato roots,while rooting powder treatment significantly increased the roots length and decreased roots surface area.The uniconazole treatment significantly increased average root diameter and root volume of all sweet-potato roots in research.The mepiquat chloride treatment increased POD activities of root in 5sweetpotato varieties,but decreased their MDA molality,but uniconazole treatment and rooting powder treatment decreased POD activities and MDA molality of all sweetpotatoes with different levels.It was different to uniconazole and mepiquat chloride,rooting powder treatment increased the SOD activities of all sweetpotato roots in research.All these three kinds of regulator treatment increased root activities of all sweetpotato roots,but only increased the zeatin riboside mass fraction of several kind of sweetpotato,and significantly decreased the gibberellin acid mass fraction of all sweetpotato root.The uniconazole treatment increased the mass fraction of abscisic acid of all sweetpotato roots,uniconazole treatment and mepiquat chloride treatment significantly increased the mass fraction of indole-3-acetic acid of several sweetpotato,while rooting powder treatment decreased the mass fraction of indole-3-acetic acid of all sweetpotato roots.To sum up,all these three kinds of plant regulator treatment significantly affected the root morphology,endogenous hormone mass fraction and physiological and biochemical indexes under drought stress,but these effects are different between different kind of plant regulator and sweet potato varieties.
