Effect of seed deterioration on the growth response of wheat under waterlogging stress

Seed deterioration and waterlogging stress are factors that lead to lower growth. On the other hand, seed deterioration may affect plant growth that plant growth can be used to quantitatively describe the components of growth analysis.
In order to investigate the mechanisms that lead to the reduction of growth and interaction of these two factors, a factorial experiment in a randomized complete block design (3 treatments seed quality for 0, 72 and 144 hours of accelerated aging and 4 treatment involves waterlogging 0, 5, 10 and 15 days of flooding) in 4 replicates. In this research, wheat seeds (Daria), first in the laboratory for seed quality treatments, were worn by accelerated aging.
The results of laboratory studies showed that seed deterioration slowing, germination and seedling growth reduction is achieved. In the greenhouse, the plants during the tillering stage control (to waterlogging stress) and heading stage control (after waterlogging stress) were collected. The tiller control, by increasing the number of plants decreased seed longevity found. The heading control between different levels of seed aging, the number of tillers per plant and seed deterioration were treated with seed deterioration increases, the number of plants was reduced, but increased the number of tillers. Tillering stage control (to waterlogging stress) that cover the whole plant is not land, leaf area and dry weight depends on the density and the deterioration of seed density decreased, but only the leaves of waterlogging stress reduced pot. At tillering control seed decay with increasing relative growth rate significantly decreased but increased in stages to control the seed deterioration relative growth rate significantly increased. One of the reasons for the increase RGR in plants from the seeds of the decline could be due to offset slow canopy closure due to low density of plants in this plant. After waterlogging stress relative growth rate, net assimilation rate, leaf area ratio and leaf weight ratio to treatment were significant seed deterioration, but to waterlogging stress and interactions were non-significant decline of seed and waterlogging stress.
Seed deterioration treatments, Waterlogging stress and their interaction were effective on the growth response mentioned in wheat
