Title

EFFECT OF ACCELERATED AGEING AND NATURAL STORAGE ON GERMINATION, SEEDLING GROWTH AND RESERVES DEPLETION OF CHICKPEA (CICER ARIETINUM L.) SEEDS

Pages

  89-103

Abstract

 This study was conducted to evaluate the effects of accelerated AGEING and natural STORAGE on seed germination and seedling heterotrophic growth of chickpea in Gorgan University of Agricultural Sciences and Natural Resources in 2014. The experiment was carried out, adopting a completely randomized design with four replications. Treatments were 8 AGEING levels (i.e., 2 years, and 4 years natural STORAGE; 1, 2, 3, 4, 5 days of accelerated AGEING and a control). The results showed that the effect of AGEING treatment on all the traits was significant. Reduction of germination percentage, germination rate, root and shoot length seed vigor index and seedling dry weight of 4 and 5 accelerated AGEING days was higher than 2 and 4 natural STORAGE years. Electrical conductivity of seed lots increased by an increase in accelerated AGEING to 4 and 5 days, which was higher than 2 and 4 natural STORAGE years. This is due to incapability of a membrane to keep its permeability, which is the result of higher sensitivity of seeds to accelerated AGEING. Reduction of the rate and EFFICIENCY OF RESERVES USED and also dynamic reserves in natural STORAGE was lower than 4 and 5 accelerated AGEING days. However, maximum rate and EFFICIENCY OF RESERVES USED and also dynamic reserves were obtained at 2 accelerated AGEING days. This could be due to increase in repair reaction rates under these conditions and activation of hydrolytic enzymes in seeds. Finally, the results of the present study revealed that damages to chickpea seed at 4 and 5 accelerated AGEING days are more than 2 and 4 natural STORAGE years, which leads to the reduction of germination percentage and rate.
