BIOCHEMICAL ATTRIBUTES OF ZINC INDUCED STRESS ON CICER ARIETINUM UNDER ABIOTIC CONDITIONS
ABDUL KARIM
Abstract
Chickpea (Cicer arietinum L,) is one of the major cultivated legume crops that is used as a source of nutrition for both of the humans and animals. Its cultivation area is widely spread all over the world but it is mainly cultivated in the arid and semi-arid areas com. It is a high protein yielding crop next to soya bean. Zinc is the micronutrient highly beneficial and its cultivation area is widely spread all over the world but it is mainly cultivated in the arid and semi-arid areas com.. The experiment was conducted at the research area of Post Graduate Agriculture Research Station (PARS), University of Agriculture Faisalabad, Pakistan. Seeds of two chick pea varieties (Bittle 2016, Noor 2019) were collected from Ayoub Agricultural Research Institute Faisalabad, Pakistan. Zinc sulphate was used as a source of zinc and was applied foliar at (0, 100, 200 and 300ppm) under normal conditions. Physiological (chlorophyll a, chlorophyll b and carotenoids) and growth attributes (fresh weight, dry weight, shoot length, root length, leaf area and number of pods per plant) analysis were determined application at different levels also varies the results, increased the yield with the increase in Zn quantity. However, adequate supply of Zn 200-300 ppm improved the 35% water holding capacity and enzymatic activities, photosynthesis, and accumulation of free leaf proline. The increasing levels of treatments also enhanced the seed quality and production.
