3、现象,表现为黔蕙萩1号、黔蕙萩2号净光合速率显著高于兴仁小白壳,黔慧萩1号净光合速率、气孔导度、胞间C02浓度及蒸腾速率均显著低于其它两个品种,此后逐渐升高,16: 00时达到峰值并显著高于其它两个意萩品种。蒸腾速率兴仁小白壳在10: 00-11: 00. 14: 0015: 00时间段高于黔蕙萩1号、黔蕙萩2号。Key:慧技;农艺性状;光合作用:S5:1008-0457 (2019) 05-0065-05 国际 DOI 编码:10. 15958/j. cnki. sdnyswxb. 2019. 05. 011Study on Agronomic and Photosynthetic Char
