目前的工作是一项广泛的综述,探讨重金属对主要豆类作物的影响,如鹰嘴豆 ( Cicer arietinum L.)、豌豆 ( Pisum sativum L.)、木豆 ( Cajanus cajan L.)、绿豆 ( Vigna radiata L.)。 )、黑豆( Vigna mungo L.)和扁豆( Lens culinaris Medik.)。豆类是全球粮食供应的重要贡献者,因为它们在为人类提供蛋白质、营养价值和健康益处方面具有巨大的有益特性。一些研究报告称,重金属对植物有害,导致植物发芽受到抑制、根和芽长度减少、呼吸速率和光合作用降低。妥善处置重金属废物已成为发达国家越来越难以解决的任务。即使在低浓度下,重金属也是豆类作物生长和生产力的重大限制因素之一。本文试图介绍在As、Cd、Cr、Cu、Pb、Ni等重金属胁迫下生长的豆类作物的形态、生化和各种生理变化。

How heavy metal stress affects the growth and development of pulse crops: insights into germination and physiological processes
The current work is an extensive review addressing the effects of heavy metals in major pulse crops such as Chickpea (Cicer arietinum L.), Pea (Pisum sativum L.), Pigeonpea (Cajanus cajan L.), Mung bean (Vigna radiata L.), Black gram (Vigna mungo L.) and Lentil (Lens culinaris Medik.). Pulses are important contributors to the global food supply in the world, due to their vast beneficial properties in providing protein, nutritional value and health benefits to the human population. Several studies have reported that heavy metals are injurious to plants causing inhibition in plant germination, a decrease in the root and shoot length, reduction in respiration rate and photosynthesis. Properly disposing of heavy metal wastes has become an increasingly difficult task to solve in developed countries. Heavy metals pose one of the substantial constraints to pulse crops growth and productivity even at low concentrations. This article attempts to present the morphological, biochemical and various physiological changes induced on the pulse crops grown under various heavy metal stress such as As, Cd, Cr, Cu, Pb, and Ni.
