盐碱胁迫对小冰麦相对生长率及茎叶离子积累的影响
Effects of Salt and Alkali Stresses on Relative Growth Rate and Accumulation of Ion in Stems and Leaves of Wheat-wheatgrass
摘要
Abstract
Seedlings of wheat-wheatgrass 33, an alkali-and salt-resistant wheat cultivar, were treated with a range of salt stress (molar ratio of NaCl: Na2SO4=1 : 1) or alkali stress (molar ratio of NaHCO3 ： Na2CO3=1: 1).The relative growth rate and contents of inorganic ions were measured.Experimental results showed that the two stresses made RGR of seedlings decreased significantly, but obviously it was decreased more under alkaline stress than under salt stress.Under alkali stress, content of Na+ was greatly increased, while contents of NO3-, SO2-4 and H2PO4- were significantly decreased, which caused a severe deficit of negative charges and imbalance of ions.关键词
