摘　　要：通过盆栽试验,研究了苗期干旱胁迫对番茄生长发育以及生理特征的影响以及干旱后复水对番茄生长形态和产量等的补偿生长效应。结果表明:番茄苗期遭遇干旱胁迫将导致植株矮化,生长发育受阻,光和速率下降;复水以后,番茄遭受干旱胁迫的植株表现出快速增长势头,在短期内赶上并超过一直充分供水的对照处理,在生长形态方面,光合速率、蒸腾速率方面,干物质累计方面以及番茄果实产量方面均表现出明显的补偿生长效应。With pot exper character, the compensat stage. The result showed iment, the effects of drought stress on tomato growth index and physiological ion effects of rewater on tomato growth and yield was researched in seeding that the drought stress will affect the plants growth, it had some injury to the height of plant and to the photosynthetic rate, transpiration rate. after rewater, the plants that experience drought stress will upgrowth quickly, they would reach and pass full-irrigation plants, and had a evidently compensation effects on growth index, photosynthetic rate, transpiration rate, total weight and yield.
