It can keep evergreen during a year.

本研究的目的是篩選出能適應長江中下游地區生長條件的常綠、抗褐斑病較強的高羊茅品種,探索與抗病性有關的相關蛋白或酶類,加速高羊茅草坪草的抗病育種進程。

Photosynthetic characteristics of three semi evergreen-evergreen poplar clone A-65/27,A-65/31 and A-61/186 were investigated.

選用A-65/27、A-65/31及A-61/1863個半常綠-常綠楊樹品系,比較了其光合速率日變化特征及光合速率的光響應和CO2響應特性。

The response on five species of evergreen trees under Cd stress was studied.

研究了 5種常綠樹木對鎘污染脅迫的反應 ,實驗結果表明 ,在高濃度鎘脅迫下 ,5種樹木葉片的葉綠素含量、細胞質膜透性、過氧化氫酶活性及鎘富集量等生理生化特性均產生明顯變化 ,但變化不盡一致。
