Effects of Root Salt Stress on Growth and Allocation of Mineral Elements in Halophyte and Glycophyte Seedlings

Abstract:

In order to understand the effect of root salt stress on seedlings, the growth, mineral elements and ash contents in halophyte Terminalia catappa and glycophyte Eriobotrya japonica seedlings were studied in greenhouse. The results showed that the spots mainly distributed on center of two seedling leaves under root salt stress, and ash content increased. There was significant positive relationship between contents of Na⁺ and Cl^- after root salt stress. The contents of mineral elements (Ca²⁺, Mg²⁺, Na⁺, K⁺, Cl^-) in seedlings varied little, but their distribution in seedlings happened to change. So, there is quantitive difference between halophytes and glycophyte under salt stress, and no qualitative difference.
