| Description |
The present investigation was conducted to study the effect of zinc deficiency on physiological, biochemical, yield and quality parameters. Two aestivum genotypes viz. WH-147 and WH-1061 and two durum genotypes viz. WH-896 and WH-912 were sown under varying levels of zinc i.e. T1- 100% Zn, T2- 50% Zn and T3- 25% Zn. Analysis of data revealed that activity of CAT, SOD, ADH, ALP decreased with the decreasing level of Zn while activity of LOX and POX increased with the decrease in zinc level. Protein profile studies revealed the appearance of new band of 34kD in bread wheat genotypes only. Also, one more band of 47kD appeared in all the genotypes at 25% zinc level. Zinc content decreased in leaves and grains but increased in roots under zinc deficiency. Physiological parameters like chlorophyll content, chlorophyll fluorescence, relative water content, chlorophyll stability index, photosynthetic rate, transpiration rate, stomatal conductance and water use efficiency declined with the decrease in zinc level. MDA content and electrolyte leakage increased under zinc deficiency. Yield parameters like plant height, biomass per plant, spike length, test weight, grain yield per plant and number of spikelet decreased with the decreasing level of zinc. Quality parameters like moisture, protein, fat, ash, crude fibre, starch content and sedimentation value declined with the decrease in zinc level. Bread wheat genotypes were found to be more tolerant under Zn deficit conditions than durum wheat. Among bread wheat WH-1061 was more tolerant. |
