Title

PHYSIOLOGICAL EFFECTS OF SALT STRESS (NACL) ON GERMINATION AND SEEDLING GROWTH OF BREED WHEAT (TRITICUM AESTIVUM L.) GENOTYPES

Pages

  119-126

Abstract

 Salinity and its control is one of the main affairs that have collated since more than thousand years ago. Difficulties related to optimal GERMINATION and plant establishment is one of the most important problems for farmers in arid and semi-arid areas. This investigation was conducted to evaluate the effects of SALT STRESS on seed GERMINATION of BREAD WHEAT cultivars; an experimental factorial in completely randomized design (CRD) with three replications. The experimental factors were 8 BREAD WHEAT cultivars with 4 levels of SALT STRESS (0, 3, 6 and 9 gr/lit Nacl). The results showed that wheat genotypes as well as between different levels of salinity on radicle length (RL), plumule length (PL), ratio of radicle length to plumule length (RL/PL), coleoptile length (CL), seedling fresh weight (SFW) and GERMINATION percentage significant difference was observed (p£0.01). It was also revealed that the ratio of radicle fresh weight to plumule fresh weight (RFW/PFW) was infiuenced significantly by genotypes (p£0.01), but the effects of stress levels on this trait was significant (p£0.05).Interaction of genotype × SALT STRESS levels on radicle length (RL) was highly significant. With increasing in the levels of SALT STRESS all traits decreased except of RL to PL ratio. The highest CORRELATION was obtained between RFW/PFW ratio and RFW (r=0.95). CLUSTER ANALYSIS, based on standardized data, classified the genotypes into three groups. Azar 2 was found to be highly salt tolerant as compared to the other genotypes and possessed higher values for all traits measured except SFW, RL to PL and RFW/PFW ratio.
