University of Guilan Iranian Journal of Seed Sciences and Research 2476-3780 5 4 2018 12 22 Effect of Irrigation Regimes on Seed Germination Characters of Promising Rapeseed Lines Effect of Irrigation Regimes on Seed Germination Characters of Promising Rapeseed Lines 35 46 2944 10.22124/jms.2018.2944 FA Mahboobeh Naderi Far student Saeed Seyfzadeh takestan azad Hamidreza Zakerin Seyed Alireza Valad Abadi takestan azad Amir Hosein Shirani Rad Journal Article 2017 09 12 In order to investigation effect of different irrigation regimes on seed germination characters in some of promising rapeseed lines, two separate split plot experimental based on CRD and RCBD design at laboratory and environmental condition, respectively, during 2015-16 cropping seasons were performed. At each experiment, different levels of irrigation––control, cut-off irrigation at the flowering stage, and cut-off irrigation at the pod formation stage––and 18 promising lines were considered as main and sub-plots, respectively. Results of analysis of variance obtained from laboratory showed that cultivar and irrigation regimes effects were significant on all of the measured characters. However, at environmental condition, only irrigation regimes, line, and their interaction effects were significant. Correlation coefficients among different characters indicated that, germination percentage under laboratory significantly correlated with final emergence percentage and final mean emerging, while correlation among electrical conductivity with some of characters such as germination percentage, daily germination and seedling dry weight was negative. Overall, our findings revealed that KS7 has desirable status than other lines. Hence, the use of this promising line for future experiments and assessing its grain yield and other related traits is recommended.
