What is Seed Priming with Putrescine Alleviated Salinity Stress During Germination and Seedling Growth of Medicinal Pumpkin about?

This investigation aimed to improve the salt tolerance of medicinal pumpkin by seed priming with putrescine and to explore the possible physiological basis of salinity tolerance. The factorial experiment based on a completely randomized design was performed to investigate the effect of putrescine pretreatment on seed germination percentage, mean germination times, seedling vigor index, seedling radicle and plumule fresh and dry weights, seedling tissue water content, dry matter, photosynthetic pigments (chlorophylls a and b, total chlorophyll, and carotenoids), proline content, malondialdehyde content, and α-amylase enzyme activity of medicinal pumpkin under salinity stress. The treatments consisted of three levels of seed priming with putrescine (0, 0.5, and 1 mM) and four salinity levels (0, 30, 60, and 90 mM of NaCl). With increasing salinity, germination percentage, seedling vigor index, radicle and plumule fresh and dry weights, and their ratio, tissue water content, dry matter, photosynthetic pigments, and α-amylase activity were reduced. However, in the seeds which had been pre-treated with putrescine, these traits were higher than those of untreated seeds. Moreover, under s
