摘要
以性状稳定的4个番茄品系为试材,利用模拟弱光环境研究弱光对番茄生长发育及产量的影响。结果表明,弱光使植株株高/茎粗增加,干质量、比叶重、叶片数、坐果率、单果质量和单株产量降低。番茄产量的降低幅度与弱光下植株各个生育期的生长特性有一定的相关性。株高/茎粗、总干质量和叶干质量、比叶重在不同生育期的变化趋势相似,但不同品系的变化程度不同,因此,可考虑用其作为番茄苗期鉴定耐弱光性强弱的指标。
The growth and yield during different developing periods of 4 stable inheriting tomato strains were investigated under low light environment （50 % light intensity of control）. The result showed that under low light environment plant height/stem diameter increased, while dry weight, specific leaf weight, leaf number, fruit rate, average fruit weight and average plant yield decreased. The changing tendencies of plant height/stem diameter ,total dry weight and leaf dry weight, specific leaf weight in different developing periods were similar, but at different extents among the tested strains. It is suggested that these parameters at seedling stage might be used as the indicator to identify the low light tolerance of tomato strains.
