| 摘 要： | 为检验增施CO2对马铃薯组培苗植株光合特性及微型薯产量的影响,选用马铃薯品种夏坡蒂组培苗为试验材料,于2015年在温室条件下进行了两批次试验。结果表明,增加CO2浓度可显著增加植株的叶面积、叶片净光合速率和胞间CO2浓度,且CO2 750μmol/mol处理>550μmol/mol处理>CK（空气）,但增加CO2浓度降低了马铃薯植株叶片气孔导度和蒸腾速率。结果还表明,增施CO2增加了马铃薯单株结薯数、单个薯重和单株产量,其增幅随CO2量的增加而增加。上述结果充分证明在温室条件下增施CO2对加速马铃薯微型薯的繁育有积极作用。

| Abstract: | The effects of CO2 supplements on photosynthetic characteristics and the micro tuber yield of the transplanted tissue-cultural potato plants were studied under the condition of the greenhouse using cultivar Shepody in 2015. The results showed that the leaf area, net photosynthetic rate and intercellular CO2 concentration with CO2 supplements were greater than those of treated with air(CK), and 750μmol/mol>550μmol/mol>CK(air). But the stomatal conductance and transpiration rate with CO2 supplements were lower than those of CK. In addition, the tuber number and tuber weight per plant treated with increasing CO2 were higher than those of CK. The results fully proved that CO2 supplements are of positive significance on micro tuber propagation via tissue-cultural potato plants under the condition of greenhouse. |
