马铃薯抑芽剂基料的筛选初报

分别用PLT、HXPLT、HMT、GZT、GLT等5种基料配制马铃薯抑芽剂，观察研究了其对马铃薯休眠后发芽的抑制效果和贮藏期的失重情况，结果表明，各制剂与对照相比，均有明显抑制发芽的作用，芽长≥1mm的芽率占总出芽率的比率均在10％左右，而对照高达75．9％。其中以HXPLT为基料的抑芽剂抑芽效果最好；以HX—PLT和HMT为基料的抑芽剂处理的马铃薯的失重率较低。综合权衡抑芽率、失重率等因素，以选用HXPLT作为马铃薯抑芽剂基料比较理想。

A Preliminary Report on Screening Base Material of Potato Sucker Controlling Agent

The experiment used the five kinds of base material of potato sucker controlling agent of PLT,HXPLT,HMT,GZT,GLT,respectively,and studied the sucker controlling agent on the inhibitory effect of germination after potato dormancy and weightlessness situation during the storage period.The results showed that compared with the check of the preparations,all obvious inhibit the role of potato sprout.The budding percentage was around 10% in the total budding percentage that sprout long more than 1 mm,while the check up to 75.9%.The effect of inhibit sprout was the best one that sucker controlling agent with HXPLT as base material,and the rate of weight loss was lower one that sucker controlling agent with HXPLT and HMT as based materials of Potato.We through integrated tradeoff for the rate of sucker controlling,weight loss and other factors,it was better well that choose HXPLT as base material of potato sucker controlling agent.
