不同番茄砧木生长特性比较

不同番茄砧木研究结果表明:BF兴津101生长势最强,其次为Besupa、128、LS-89,北京1号生长势最弱。与其它番茄砧木相比,BF兴津101的根系活力、叶绿素含量、根鲜重及茎叶鲜重均显著高于其它砧木品种,光合最大值分别比Besupa、128、LS-89和北京1号高出5.0％、10.0％、19.1％、31.6％。从增强养分吸收和干物质积累方面考虑,BF兴津101可以作为嫁接换根首选砧木,其次为Besupa、128、LS-89。

Comparison of growth characteristics of different tomato rootstocks

The result indicated that BFxingjin101 growed best, Beijing No.1 growed worst and Besupa, 128 and LS - 89 were between them. Compared with other tomato rootstocks, the root activity, leaf chlorophyll content, fresh weight of root and fresh weight of stem and leaf of BFXingjin101 were markedly higher. The maximum of photosynthesis is 5.0% ,10.0% ,19.1% and 31.6% higher than Besupa, 128, LS- 89 and Beijing No.1 respectively. Considering the absorption of nourishment and accumulation of dry matter, BFxingjin101 could be as the preferred rootstock of graft,the next were Besup 128 LS - 89.
