丛枝菌根真菌对葡萄幼苗抗旱性的影响研究

Effect of arbuscular mycorrhizal fungi on drought resistance of grape(Vitis vinifera L.) seedlings

研究了丛枝菌根真菌(AMF)对葡萄幼苗水分代谢及抗旱性的影响,结果表明:正常供水条件和干旱条件下AMF都能影响葡萄苗的水分代谢,改善叶片水分状况,增强蒸腾作用,从而增强其抗旱能力;而干旱胁迫下AMF改善葡萄苗水分状况的作用明显强于正常供水条件下,表明AMF在逆境条件下作用更明显;通过对葡萄苗膜保护系统的影响研究,发现AMF能增强葡萄苗叶片膜保护酶活性,降低植株叶片膜脂过氧化程度,从而缓解干旱对质膜透性的破坏,增强葡萄植株的抗旱性。

This paper claborates the standardization production techniques of grape protected cultivation to promote early maturing in China. It mainly includes the cultivation facilities design and environment regulation, evaluation and selection of suitable varieties and root stock, orchard establishment, high photosynthetic efficiency tree form and leaf canopy and simplified pruning.fertilizer and water efficient utilization. dormancy regulation,quality regulation and Se-enriched fruit production, high yield in successive years and so on.
