番茄种子包衣剂的研究──杀菌剂和激素的筛选

STUDIES ON SEED COATING FORMULATION IN TOMATO -SELECTION OF THE GERMICIDES AND THE HORMONES

通过平皿培养法、吸湿培养法和玻板直立发芽法对所供试的四种杀菌剂作综合性分析与筛选、包衣液中杀菌剂的浓度降至０．２５％时，５８％甲霜灵锰锌的杀菌效果与种子发芽情况最好，但对番茄种子的生活力仍有一定的不良影响，在含有一定量杀菌剂的包衣剂中通过加入极少量的赤霉素可克服杀菌剂带来的负作用，并能使番茄种子的生活力提高。

In this experiment, through platiculture and two other culture methods four kinds of offered germicide were synthetically analysed and tested. As a result, the germicide, 48% Metalaxy1+10% Mancozeb WP, was selected. Further more, as the germicide consistency of the seed coating formulation was reduced to 0. 25%,germicidal efect and seed germination reached the utmost point. And the negative effect and seed germination reached the utmost point. And the negative effect on tomato seed vitality still existed. By adding a tiny amount of gibberellin to .the formulation, the problem got to be overcome and tomato seed vitality increased.
