Abstract:
Salinity stress significantly impacts crops, disrupting their water balance and nutrient uptake, reducing growth, yield, and overall plant health. High salinity in soil can adversely affect plants by disrupting their water balance. Excessive salt levels can lead to dehydration, hinder nutrient absorption, and damage plant cells, ultimately impairing growth and reducing crop yields. Gallic acid (GA) and zinc ferrite (ZnFNP) can effectively overcome this problem. GA can promote root growth, boost photosynthesis, and help plants absorb nutrients efficiently. However, their combined application as an amendment against drought still needs scientific justification. Zinc ferrite nanoparticles possess many beneficial properties for soil remediation and medical applications. That\'s why the current study used a combination of GA and ZnFNP as amendments to wheat. There were 4 treatments, i.e., 0, 10 µM GA, 15 μM GA, and 20 µM GA, without and with 5 μM ZnFNP applied in 4 replications following a completely randomized design. Results exhibited that 20 µM GA + 5 μM ZnFNP caused significant improvement in wheat shoot length (28.62%), shoot fresh weight (16.52%), shoot dry weight (11.38%), root length (3.64%), root fresh weight (14.72%), and root dry weight (9.71%) in contrast to the control. Significant enrichment in wheat chlorophyll a (19.76%), chlorophyll b (25.16%), total chlorophyll (21.35%), photosynthetic rate (12.72%), transpiration rate (10.09%), and stomatal conductance (15.25%) over the control validate the potential of 20 µM GA + 5 μM ZnFNP. Furthermore, improvement in N, P, and K concentration in grain and shoot verified the effective functioning of 20 µM GA + 5 μM ZnFNP compared to control. In conclusion, 20 µM GA + 5 μM ZnFNP can potentially improve the growth, chlorophyll contents and gas exchange attributes of wheat cultivated in salinity stress. More investigations are suggested to declare 20 µM GA + 5 μM ZnFNP as the best amendment for alleviating salinity stress in different cereal crops.
摘要:
盐度胁迫显著影响作物,破坏他们的水平衡和营养吸收,减少增长,产量,和整体植物健康。土壤中的高盐度会破坏植物的水平衡,从而对植物产生不利影响。过量的盐含量会导致脱水,阻碍营养吸收,破坏植物细胞,最终损害生长和降低作物产量。没食子酸(GA)和铁酸锌(ZnFNP)可以有效地克服这一问题。GA可以促进根系生长,促进光合作用,帮助植物有效吸收营养。然而,它们作为干旱修正案的联合应用仍然需要科学依据。铁酸锌纳米颗粒对土壤修复和医学应用具有许多有益的特性。这就是为什么当前的研究使用GA和ZnFNP的组合作为小麦的改良剂。有4种治疗方法,即,0,10µMGA,15μMGA,和20µMGA,在完全随机设计后,不使用和使用5μMZnFNP重复4次。结果表明,20μMGA+5μMZnFNP引起小麦芽长度的显着改善(28.62%),芽鲜重(16.52%),芽干重(11.38%),根长(3.64%),根鲜重(14.72%),与对照相比,根干重(9.71%)。小麦叶绿素a显著富集(19.76%),叶绿素b(25.16%),总叶绿素(21.35%),光合速率(12.72%),蒸腾速率(10.09%),与对照组相比,气孔导度(15.25%)验证了20µMGA+5μMZnFNP的电势。此外,N的改进,P,与对照相比,谷物和枝条中的K浓度验证了20µMGA5μMZnFNP的有效功能。总之,20μMGA+5μMZnFNP可以潜在地改善生长,盐分胁迫下栽培小麦的叶绿素含量和气体交换特性。建议进行更多的研究,以宣布20µMGA5μMZnFNP为减轻不同谷类作物盐分胁迫的最佳改良剂。
