The mutual grafting affecting the physiological characteristics and selenium (Se) absorption capacity in offspring of Solanum photeinocarpum from the farmland and mining ecosystems were studied by the pot experiments. The mutual grafting significantly increased the dry biomass, antioxidant enzyme activity, and soluble protein content in offspring of S. photeinocarpum from the farmland ecosystem, while the activities of superoxide dismutase and catalase in offspring of S. photeinocarpum from the mining ecosystem were inhibited than the ungrafted S. photeinocarpum. It was observed that the photosynthetic pigment level of S. photeinocarpum offspring from the farmland ecosystem was lower than the ungrafted S. photeinocarpum to varying degrees. Besides, mutual grafting not only increased the Se concentration of S. photeinocarpum offspring, but also significantly promoted the amount of extracted Se by S. photeinocarpum offspring. The shoots Se extraction and dry biomass of S. photeinocarpum offspring with combination of S. photeinocarpum from the mining ecosystem / S. photeinocarpum from the farmland ecosystem reached the maximum level, thereby promoting the growth and Se accumulation capacity of S. photeinocarpum offspring than another grafting combination.

两种生态系统互嫁马茄对硒胁迫下子代生理及硒吸收的影响-【维普网】-仓储式在线作品出版平台-www.cqvip.com

通过盆栽试验,研究了相互嫁接对农田和矿山生态系统中龙葵子代生理特性和硒(Se)吸收能力的影响。相互嫁接显着提高了农田生态系统光果子代的干生物量、抗氧化酶活性和可溶性蛋白含量,而采矿生态系统光果子的超氧化物歧化酶和过氧化氢酶活性受到抑制。未嫁接的S. photeinocarpum。观察到,农田生态系统的S. phoeinocarpum后代的光合色素水平低于未嫁接的S. photeinocarpum不同程度。此外,相互嫁接不仅提高了光果子代的硒浓度,而且显着提高了光果子代提取硒的量。芽硒提取和干生物质少花龙葵用的组合后代少花龙葵从采矿生态系统/少花龙葵从农田生态系统达到最大水平,从而促进生长和硒累积容量少花龙葵后代比另一嫁接组合。
