摘  要:
以番茄品种"中杂105"为试验材料,以钢瓶CO2为碳源,设置700、1 000、1 300μmol/mol3个CO2浓度,对照组为不增施CO2,研究了不同浓度的CO2对苗期及果期番茄光合作用、光响应曲线、SPAD值以及开花日期的影响。结果表明:高浓度CO2显著提高了叶片的SPAD值,提高净光合速率,提高了叶片的最大净光合速率以及光补偿点,有利于开花节位数的降低以及开花日期的提前。

摘  要:
With the tomato type ‘Zhongza 105'as material and used CO2 cylinder,700,1 000,1 300μmol/mol CO2 concentration were set,with no CO2 as control group.The effect of different CO2 concentrations on the photosynthesis,photo response during seedling and fruit stage,SPAD value,the flowering time and inflorescence node of tomato were studied.The results showed that high CO2 concentration significantly improved SPAD value and net photosynthesis rate,improved maximum photosynthetic rate and light compensation point,lowered the inflorescence node and brought forward the flower time.
