| Abstract | ||
| The present study was carried out for possibility of using Zn(NO₃)₂ in alleviating of negative effects for salt stress using of sunflower (Helianthus annuus L.) . Results showed that saline level ( 8 dS.m-1) reduced growth parameters including fresh & dry weight , chlorophyll content & transpiration rate in seedlings . In other hand, this salt rate caused significant increase in percentages of salts effect for shoot and root and ratio of ions leakage (plasma membrane damage). Providing of seedlings with Zn(NO₃)₂ has improved growth indicators through significant encourage for range of fresh & dry weight , chlorophyll content , transpiration rate , in addition through reducing of negative salts effect percentage of shoot & root and percentage of plasma membrane damage reaching levels which approach to control treatment (unstress seedling ) . | ||
