Abstract：
The excessive accumulation of sodium chloride (NaCl) in soil can result in soil salinity, which poses a significant challenge to plant growth and crop production due to impaired water and nutrient uptake. On the other hand, hydropriming (WP) and low level of NaCl priming can improve the germination of seeds, chlorophyll contents, oil and seed yield in plants. That\'s why this study investigates the impact of hydro and different levels of NaCl (0.5, 1.0, 1.5 and 2.0%) priming, as pre-treatment techniques on canola seeds germination, growth and yield of two varieties Punjab and Faisal Canola. Results showed that, WP performed significant best for increase in germination (~ 20 and ~ 22%) and shoot length (~ 6 and ~ 10%) over non-priming (NP) in Punjab Canola and Faisal Canola respectively. A significant increase in plant height (~ 6 and ~ 7%), root length (~ 1 and ~ 7%), shoot fresh weight (~ 5 and ~ 7%), root fresh weight (~ 6 and ~ 7%) in Punjab Canola and Faisal Canola respectively. It was also observed that plants under WP and 0.5%NaCl priming were also better in production of seed yield per plant, oil contents, silique per plant, seeds per silique, and branches per plant chlorophyll contents and leaf relative water contents over NP. In conclusion, WP and 0.5%NaCl has potential to improve the germination, growth, yield and oil attributes of canola compared to non-priming, 1.0%NaCl priming, 1.5%NaCl priming and 2.0%NaCl priming.
摘要：
土壤中氯化钠（NaCl）的过度积累会导致土壤盐碱化，由于水分和养分吸收受损，这对植物生长和作物生产构成了重大挑战。另一方面,水引发（WP）和低水平的NaCl引发可以提高种子的萌发，叶绿素含量，植物中的油和种子产量。这就是为什么这项研究调查了水力和不同水平的NaCl（0.5，1.0，1.5和2.0％）启动的影响，作为油菜种子萌发的预处理技术，两个品种旁遮普和费萨尔油菜的生长和产量。结果表明,在旁遮普油菜和Faisal油菜中，WP的发芽率（〜20％和〜22％）和芽长度（〜6％和〜10％）分别高于非引发（NP）。株高显著增加(~6%和~7%)，根长(~1和~7%)，射击鲜重（〜5和〜7％），旁遮普油菜和Faisal油菜的根鲜重（分别为〜6和〜7％）。还观察到，在WP和0.5％NaCl引发下的植物在每株植物的种子产量方面也更好。含油量,每种植物的silique，每个角果的种子，NP上的单株叶绿素含量和叶片相对含水量。总之,WP和0.5％NaCl具有改善发芽的潜力，增长,与非引发相比，油菜的产量和油属性，1.0%NaCl引发,1.5%NaCl引发和2.0%NaCl引发。
