“…The results of this study are based on the decrease of LRWC under late planting date and late-season drought stress, which correspond with the results of other researchers (Zeleke et al, 2014;Shirani Rad et al, 2014b;Mamnabi et al, 2020). NI conditions probably increased the moisture in the plant roots and, eventually, the LRWC due to the high water uptake by the rapeseed plant roots.…”

“…The results of this study are based on the decrease of TCC under late planting date and late-season drought stress, which correspond with the results of other researchers (Abu-Muriefah, 2015;Shekari et al, 2015;Mamnabi et al, 2020). Late planting and the shortened growth period seem to have caused the plant to enter the overwintering period with a weak rosette.…”

“…The results regarding late planting on LPC showed different results in this experiment than some recorded by Safavi Fard et al (2018), Sabagh et al (2019) and Mamnabi et al (2020), who reported that LPC increased in late planting and stress conditions. The results obtained in this study, which correspond with the reported data of other researchers (Gill and Tuteja, 2010;Sanchez-Rodriguez, 2010).…”

The adverse effects of abiotic stresses have always restricted oilseed crop production, particularly in arid and semi-arid regions. On the other side, global climate change has led us to adapt planting dates and select tolerant cultivars to encounter the new climatic conditions. To evaluate the effect of late-season drought stress under different planting dates on rapeseed cultivars, an experiment was conducted as a factorial split-plot based on randomized complete block design in Karaj region- Iran, during 2015-2017. Planting date and irrigation treatments were considered in the main plots as factorial and cultivars were placed in subplots. Two planting dates were regular date (October 7) (PD1) and late planting date (November 6) (PD2). Irrigation was also carried out at two levels of normal irrigation (NI) and irrigation interruption from flowering stage onwards (II). Experimental cultivars included ES Hydromel, ES Alonso, ES Darko, ES Lauren, and Ahmadi. According to the results, late-season drought stress and delayed planting date reduced leaf relative water content (LRWC), total chlorophyll content (TCC), proline (LPC), and grain yield (GY), and increased stomatal resistance (SR), canopy temperature (CT), and leaf soluble carbohydrates (CLS) in rapeseed cultivars. The highest grain yield (4505.6 kg ha-1) was obtained in NI conditions and PD1. Significant interactions of planting date, irrigation, and cultivar on LRWC, SR, and CLS traits indicated that the ES Hydromel was the most tolerant hybrid cultivar with the highest LRWC and the lowest SR and CLS levels compared to other ones in unfavorable conditions of late-season drought stress and delayed planting. To confirm these results, cluster analysis led to the formation of two clusters, where ES Darko, Ahmadi, and ES Lauren cultivars were placed in the sensitive cluster and ES Hydromel and ES Alonso cultivars were assigned to the tolerant cluster. Therefore, ES Hydromel can be introduced as a superior cultivar to be selected as a genotype that presents acceptable resistance under drought stress and late sowing in arid and semi-arid regions.

“…Rapeseed/canola (Brassica napus L.) is mainly specified as a major oilseed crop due to its high oil content and the useful fatty acid compositions (Zhou et al 2019;Mamnabi et al 2020). This crop has been largely cultivated all over the world in recent years (Torkaman et al 2018).…”
