几个树种对模拟海风抗性比较结果，木麻黄和夹竹桃为高抗树种；粗枝木麻黄、细枝木麻黄和湿地松属中抗树种；山地木麻黄抗性较差。游离脯氨酸（ｐｒｏ）测定结果，参试树种经“海风”逆境的影响后，游离脯氨酸有不同程度的增加，初期随刮“海风”次数增加积累迅速增加，木麻黄受“海风”连续吹６天后，ｐｒｏ浓度最高，而继续刮“海风”时，ｐｒｏ的积累不但不再增加，反而呈递减趋势。几个种苗在正常环境下或在“海风”的影响后ｐｒｏ积累量变化很大，抗“海风”刀的强弱与ｐｒｏ浓度无明显规律。
The resistance of several tree species to simulated sea breeze was compared with that of Casuarina equisetifolia and oleander, which were highly resistant to tree species. The species of Brassica parachinensis, Epimedium brevichedra and Pinus elliotti var. Free pro proline (pro) determination results, the test species after the “sea breeze” adverse effects, the free proline increased in varying degrees, the initial increase with the scraping “sea breeze” increased the accumulation of rapid increase, Casuarina by the “sea breeze” After 6 consecutive puffs, the highest pro concentration, while continuing to scrape the “sea breeze”, the pro accumulation not only did not increase, but showed a declining trend. Several seedlings under normal circumstances or in the “sea breeze” after the impact of pro accumulation varies greatly, anti “sea breeze” knife strength and pro concentration no obvious law.
