Enhancing Industrial Crop Resilience: Effects of Salinity and Exogenous Putrescine Supplementation on Growth, Biochemical, and Enzymatic Attributes of Cicer arietinum L
摘要
Salt stress affects plants physiologically, biochemically, and molecularly. Chickpeas, the world's most widely grown grain legume, are susceptible to abiotic stresses including moisture stress, droughts, cold, high temperatures, salinity, and alkalinity. An application of polyamines such as putrescine (P) containing nitrogen can be used to combat abiotic stress. The present study applied a combination of salt (S) and putrescine (3,000 µM P + 40,000 µM S; 5,000 µM P + 40,000 µM S; 8,000 µM P + 40,000 µM S), alongside putrescine and salt separately to 2 d old chickpea seedling. Before treatment, these seedlings were placed in a Hoagland solution that acts as hydroponics. After 7 d of treatment, these seedlings were tested for growth, biochemical, and enzymatical parameters, and their tolerance capacity toward stress was adjudicated. Among the putrescine-treated plants, the highest concentrated chickpea showed the maximum tolerance capacity in all respects. However, the salt-treated chickpea seedlings did not tolerate it as expected. However, the combinatorial putrescine and salt-treated chickpea seedlings tried to significantly nullify salt stress's effects. Therefore, it can be recommended that chickpea seedlings be treated with putrescine while growing in salt-stress conditions to overcome stress-related issues.
