摘要
以番茄品种月光、合作903为试材,在CO2浓度为1000μmol·mol-1的条件下,研究了高浓度CO2对番茄生长量、干物质分配、产量、品质及光合作用的影响。结果表明,高浓度CO2显著抑制番茄株高、茎粗、节间长度的增长;有利于干物质向果实分配,减少了向茎、叶的分配;显著提高了产量和品质。净光合速率在处理前期显著提高,中期适应,后期再次提高。
Under elevated CO2 concentration （ 1 000 μmol · mol^-1 ）, effects of elevated CO2 concentration on the growth quantity, distribution of dry weight, yield, quality and photosynthesis of tomato were studied. The results showed that elevated CO2 concentration inhibited the plant height, stem diameter and internode length of tomato significantly, and increased the dry matter distribution rate to fruit, decreased distribution rate to stem and leaf, thus increased the yield and improved the quality of tomato significantly. The net photosynthetic rate increased in the early-term sigifieantly, kept stability in the medium-term and increased again in the latter.
