The results on the fitness of F1 showed that both of those two kinds of F1 had good germination and growth rate, which was not significantly different from that of wild B. juncea. However the seed setting of F1 with glufosinate-resistant gene and glyphosate-resistant gene were only 0.50 and 0.61 per silique, which decreased significantly compared to that of self-pollination of wild B.

ML^(-1);(2) The allelopathic effects of the leaves and inflorescences of Solidago canadensis on these three crops are strong than those from the stems;(3) Among these three crop species, the seed of Brassica chinensis var. communis is more sensitive to the water extract of Solidago canadensis than those of Capsicum annuum, Lycoperiscum esculetum.

mL^(-1)浓度处理下，甚至使作物种子失去活力；(2)加拿大一枝黄花叶和花序的水浸提液对种子萌发和生长的影响要大于其茎的浸提液；(3)在3种作物中，长梗白菜种子对加拿大一枝黄花水浸提液的敏感性最高。

This experiment adopts artificial simulation research approaches, namely using the standardized moisture stress conditions with hypertonic solution to immerge rubber tree seeds during germination to elementarily select out some rubber seedlings, which could stand the high-osmosis stress. The germination characteristic of the rubber tree seed under high-osmosis stress was observed and the phenomena of growth and dynamic changes of physiology and biochemistry were determined and analysed, and then its ability of drought-resistance was valued.

本试验采用人工模拟研究方法，利用高渗溶液提供标准化的水分逆境条件，对催芽过程中的橡胶树种子进行人工胁迫处理，并筛选出耐高渗胁迫的橡胶籽苗，观测种子的萌发特性和选出籽苗的生理生化特性并对其抗旱性作出评价。
