The Effect of Physical Priming of Seed on Traits and Yield of Corn (Zea Mays L.) Under Water Deficit Conditions in Iran

Abstract

Siyami et al. : The effect of physical priming of seed on traits and yield of corn (Zea mays L.) under water deficit conditions in Abstract. In order to study the effect of physical priming of seed on traits and yield of corn under water deficit conditions, a two years experiment was conducted during 2014-2015 as a split plot with three replications in Iran. The main factor includes two levels of irrigation (70 and 110 mm evaporation from pan class A as control and water deficit, respectively) after 8-9 leaves stage of corn and sub-factor includes corn seed treatment with gamma and beta rays, laser wave, magnetic field and ultrasonic waves, all in time intervals of 5 and 10 min. along with a non-primed control. Results indicated that maize seed priming under magnetic field of 5 and 10 min. and gamma and laser rays for 5 min. in normal irrigation regime were the best treatments with 20%, 18%, 16% and 13% increase value, respectively, while seed priming with gamma and laser rays for 10 min. under water deficit condition had the lowest grain yield.To increase corn grain yield in both normal and water deficit conditions, seed priming with the magnetic field in both time intervals, gamma and laser rays only in a short time is recommended.

Impact of Pre-Sowing Red Light Treatment of Sweet Corn Seeds on the Quality and Quantity of Yield

“…Consumers want their food Agriculture 2020, 10, 165 2 of 10 products to be safe and healthy. Hence, physical, environmentally-friendly methods of seed treatment have been gaining considerable popularity [6]. Their purpose is to trigger physiological and biochemical changes in the seeds, and ultimately increase their vigor.…”

“…can have a positive impact on some plant properties (seed sprout rate, plant emergence and development, fresh mass increase, harvest yield, etc.) [6][7][8][9][10][11][12][13][14][15][16].…”

“…Pre-sowing treatment of seeds affects sprout rates and seedling growth, which in turn conditions the resulting harvest yield, nutrient content, and capacity to absorb sunlight [1,6,18]. The advantage of physical treatment methods stems from the fact that while the yield increase is maintained, the methods are also safe to the natural environment, which was what first drew us to this research topic.…”

“…Pre-sowing seed treatment affects sprout rates and seedling development, which in turn affects harvest yield, nutrient content, and sunlight absorption ability [23][24][25]. Physical treatment approaches have the benefit of maintaining yield while still being healthy for the climate, which is what drew us initially to this research subject.…”

“…With this treatment, young plants will gain greater resistance to environmental stress and thus faster development and greater plant vigor will be noticed (Rhodes & McCarl 2020, Seran & Sutha-mathy 2013. Seed treatment before sowing affects germination rate and seedling growth, which in turn determines higher yield (Dziwulska-Hunek et al 2020, Siyami et al (2018.…”
