Title

EFFECT OF EXOGENOUS ABSCISIC ACID AND CYTOKININ ON WHEAT (TRITICUM AESTIVUM)

Pages

  45-58

Abstract

 CK and ABA not only regulate the process of senescence, but also have major roles in the formation of SINK and source strength capacity. This study carried out to determine effect of exogenous application of ck and ABA(100Mm ) at the 9 levels: 1 - Control, 2 - CK at the time of appearance, 3 - CK 14 days after its SPIKE EMERGENCE 4 - ABA at the time of appearance 5 - ABA 14 days after its SPIKE EMERGENCE, 6 - CK at the time of appearance and ABA 14 days after its SPIKE EMERGENCE, 7 - ABA at the time of appearance and CK 14 days after its SPIKE EMERGENCE, 8 - ABA at the time of 1 and 14 days after its SPIKE EMERGENCE, 9 - CK at the time of 1 and 14 days after its SPIKE EMERGENCE, on some aspects in different steps of WHEAT growth in using a Randomized complete Block design(RCBD) with three replications in experimental field of Islamic Azad university of Karaj branch in growing season 1387- 88. Results showed that when these PLANT GROWTH REGULATORS applied at different stages of spike appearance and 14 days after its SPIKE EMERGENCE, GRAIN YIELD, harvest index (HI), 1000 grain weight, were meaning fully influenced by the exogenous application of the two regulators. The highest GRAIN YIELD (738.09 gr/m2) one related to exogenous application of CK at the time of SPIKE EMERGENCE. The highest hardest index and number grain spike is related to the exogenous application of CK at both time (1 and 2). The highest 1000 grain weight is related to the exogenous application of CK at the time of appearance and ABA 14 days after its SPIKE EMERGENCE respectively. The results of the study showed that exogenous application of CK at cell division and ABA at grain filling on stage in grain growth phase may significantly improve GRAIN YIELD.
