Seed Germination Behaviors Of Some Aerobic Rice Cultivars (Oryza Sativa L) After Priming With Polyethylene Glycol-8000 (Peg-8000)

摘要

Seed Priming Is Famous Technique To Accelerate Seed Germination Behaviors. This Experiment Was Conducted To Study The Effect Of Polyethylene Glycol-8000 (Peg-8000) As Priming Agent On Seed Germination Behavior Of Some Aerobic Rice Cultivars (Oryza Sativa L). Experiment Was Carried Out By Using Two-Factor (Three Aerobic Rice Cultivars And Peg) With Four Replications, Which Arranged In Factorial System Design And Conducted With Completely Randomized Design. The Factor Was Varieties Which Were Inpago 8 (V1), Ir64 (V2) And Situbagendit (V3), Combine With 4 Levels Of Peg Concentrations (0,100, And 200 Gl-1) And Control With No Treatment. Experiment Was Repeated 4 Times So Total Number Of Experimental Units Were 48). Germination Parameters Measured Were Germination Percentage, Germination Index, Days Of 50% Germination, Seedling Fresh Weight (Mg), Seedling Shoot Fresh Weight And Root Fresh Weight (Mg), Seedling Dry Weigh (Mg), Seedling Shoot Dry Weight And Root Dry Weight (Mg), Shoot/Root Ratio, Seedling Length (Cm), Seedling Root Length (Cm) And Shoot Length (Cm) And Seed Vigor Index. The Results Indicated That Seed Priming Significantly Affected Germination Behaviors Compared With Control Depending Upon Varieties. The Highest Germination % Was Obtained Under Laboratory And Greenhouse Condition By The Treatment Of Peg 200 G L-1 On The Situbagendit And Ir-64 Variety (90.25% And 93.33%, Respectively), Compared To Control In Inpago-8 In Both Laboratory (75.75%) And Greenhouse (80%) . As Implementation To Increase Seed And Seedling Vigor Of Rice It Is A Best Practice To Use Peg Priming With 200 Gl-1 Solutions Depend Upon Varietal Response, And We Suggest That More Research About The Effect Of Peg As Seed Priming Techniques On Seed Germination Behavior Of Many Grain Crops Is Needed To Confirm The Methodology.
