Title

Effects of salinity stress on some morphological, physiological traits, yield and yield components of different rapeseed cultivars

Pages

  91-102

Abstract

 Salinity stress is most important factor limiting crops growth and production in worldwide. The aim of this study was to determine the effects of four water salinity levels (1. 15, 4, 7 and 10 dS. m-1) on some traits of phonology, morphology, yield and yield components of four canola (Brassica napus L. ) Cultivars (Hyola 4815, 308 and 401 and RGS 003) under application of 10 Ton. ha-1 vermicompost in 2014-15 in Gorgan region, Iran. The experiment was conducted as factorial arranged in randomized complete blocks design with three replications. The results showed that the all traits, except days to seed emergence and pod length were significantly affected by Cultivar. The Hyola 4815 Cultivar had the lowest total plant height, height of first pod and branch from ground, stem diameter and seeds per pod with a significant difference with other Cultivars. The lowest number of branches and highest days to flowering and maturity and stem diameter were obtained from RGS Cultivar with a significant difference with the other Cultivars. The Hyola 308 and 4815 Cultivars with the highest number of pods per plant were significantly different with Hyola 401 and RGS Cultivars. The highest 1000-seed weight was found in Hyola 4815 and 401 with a significant difference with the other Cultivars. Hyola 308 and 401 Cultivars had the highest seed yield and their differences were significant with RGS Cultivar. However, seed yield differences of these three Cultivars were not significant with Hyola 4815 Cultivar. Salinity significantly decreased the number of days to maturity (2. 6 days) and 1000-seed weight. Increased salinity from 1. 15 to 7 dS. m-1 significantly increased pods per plant (22%) and seed yield (30%), but they decreased when salinity increased to 10 dS. m-1, although this reduction was not significant. The results showed that Hyola 401 had a comparative advantage in almost all traits.
