滨海盐碱地长期人工刺槐林的生长状况和叶片特性
Growth Status and Leaf Characteristics of Longterm Locust Plantations in Coastal Saline Soil
摘要
Abstract
In order to explore the response of longterm locust plantations to costal soil salinization, the differences in growth status and leaf characteristics among 3 locust plantations with different degradation degrees were compared in this paper. The results showed that the general growth status of locust plantations was less desirable, having a survival percentage of less than 70%, due to longterm soil salinization. Significant differences in DBH (diameter at breast height), tree height and canopy density were found among 3 locust plantations. The severely degraded locust plantation had a worse status of leaf nutrition, lower content of chlorophyll and weaker ability of stress tolerance, with enhanced ratio of bound water to free water in leaves, increased contents of malondialdehyde (MDA) and praline, and decreased activities of superoxide dismutase (SOD) and peroxidase (POD).关键词
