Abstract: (485 Views)
This experiment aims to investigate the effect of foliar spraying of polyamines on growth traits, root characteristics, physiological traits and seed yield and yield components of the Camelina plant at different levels of salinity stress, a pot factorial experiment based on a completely randomized design was done in 2021 at Payam Noor University. The first factor was the salinity stress with Urmia lake water at three levels (0, 15 and 30 dS/m) and the second factor was foliar spraying polyamines at four levels (spermine, spermidine, putrescine and control (spraying with water)). The results showed that the salinity stress of 30 and 15 ds/m in comparison with the control decreased root diameter (16 and 4 percent), root dry weight (39 and 17 percent), root volume (43 and 31 percent), relative leaf water content (60 and 23 percent), chlorophyll a concentration (57 and 13 percent), chlorophyll b concentration (61 and 21 percent), the number of capsules per plant (52 and 25 percent), the weight of 100 seeds (30 and 5 percent), seed yield (52 and 10 percent), and biological yield (38 and 10 percent), respectively. But salinity stress at 30 and 15 ds/m increased leaf temperature (12 and 6%), carotenoid concentration (56 and 46%), and leaf proline concentration (44 and 40%), respectively. Foliar spraying with spermine, spermidine and putrescine in comparison with no foliar spraying, enhanced the number of capsules per plant (26, 23 and 24%), weight of 100 seeds (28, 17 and 12%) and seed yield (38, 8 and 21 percent), respectively. On the other hand, it reduced the effects of salinity stress. Therefore, it seems that the Camelina plant can tolerate salinity up to 15 dS/m. Foliar spraying with polyamines can be a good approach to improving the tolerance, growth and yield of Camelina under salinity stress conditions.
