الملخص EN

A field experiment was carried out in a private field in Babylon governorate / AlMashrooa-Al-Mussseib during winter season of 2013-2014 in a sandy , loam soil, to find out the effect of plant growth regulators and phytoextracts on grain filling period and its growth rate for some bread wheat cultivars.

A factorial in Randomized Complete Block Design (R.C.B.D) was followed with three replicates, using plant growth regulators (Salicylic acid and Kinetin) with a concentration of 100 mg.L-1 , and two phytoextracts (Liquorices and Willow bark) with 100% concentration.

Distilled water was used as a control in this study, and three spray stages for three bread wheat cultivars.

Treatment with Kinetin (R4), at the start of tillering(s1), resulted in significant difference by giving highest grain growth rate and shortest grain filling duration to reach the physiological maturity of grain.

while Liquorices extract(R3) treatment at the start of tillering stage dominated by giving highest plant growth rate.
