油茶移栽苗失水程度对生理生化特性的影响
Effects of dehydration degree on the physiological and chemical characteristics of Camellia oleifera seedlings
摘要
Abstract
Relationship between the dehydration degree of Camellia oleifera seedlings and the enzyme activities of polyphenoloxidase(PPO), peroxidase(POD),catalase (CAT), and other characteristics such as the content of MDA, the relative conductivity and planting survival rate were studied in this paper. The results showed that when the oil-tea seedlings dehydrated by 10％, 20％, 30％ and 40％, the activity of PPO were respectively 0.654,0.734, 0.612 and 0.513 U.min-1·g-1; the activity of POD were respectively 13.635, 16.514, 12.511 and 9.021 U·min-1·g-1; the activity of CAT were respectively 3.153, 4.021, 3.011 and 1.412 U·min-1·g-1; the content of MDA were respectively 45.28, 50.98, 61.42 and 73.72 μmol·g-1; the relative conductivity were respectively 34.88％,38.07％, 48.90％ and 50.45％; the planting survival rates were respectively 91.1％, 80.0％, 6.7％ and 0％. The seedlings should be kept fresh and the dehydration degree maintains within 20％ in the planting process.关键词
