Abstract
Article history: In order to study the effects of foliar spray of the plant hormones Cytokinins (CK) and Abscisic Acid (ABA) at pollination and grain filling stages of wheat a trial was conducted arranged in RCBD with seven treatments and five replications in Agricultural College of Mahabad Azad University in 2013. The treatments were as follows: b1: No spray (Check), b2: CK foliar spray at pollination, b3: CK and ABA foliar sprays at pollination and grain filling, b4: CK foliar spray at pollination and grain filling, b5: ABA foliar spray at pollination, b6: ABA foliar spray at pollination and grain filling, b7: CK and ABA foliar sprays at pollination. The foliar application results of these two plant hormones at different growth stages showed that number of seeds per spike, 1000-kernel weight, biological yield, grain yield and harvest index were significantly affected. The greatest grain yield, harvest index and number of seeds per spike were obtained by foliar applications of CK at pollination and grain filling (b4) and of CK at pollination (b2). The greatest biological yield was obtained by foliar applications of CK at pollination and grain filling (b4) and the greatest 1000-kernel weight was obtained by foliar applications of CK at pollination (b2). The plant hormones treatments didn't significantly affect the plant height and rootlet length.
