Abstract
Plant growth regulators such as mepiquat chloride (MC) and chlormequat chloride (CCC) are used to establish the balance between the vegetative and generative growth in cotton. This study was conducted to compare the different doses and application time of CCC with MC and un-treatment (control). The seven treatments including control (non-treatment), T1 (three sprays of chlormequat chloride), T2 (two sprays of mepiquat chloride), T3 (0.4 L ha-1 CCC), T4 (0.5 L ha-1 CCC), T5 (0.6 L ha-1 CCC) and T6 (0.7 L ha-1 CCC) were laid out in Randomized Complete Block Design with four replications. The differences among treatments were found to be significant for seed cotton yield (SCY), the number of bolls per plant (N/B), boll weight (BW), plant height (PH), earliness, ginning out-turn (GOT), fiber fineness (FF), specific seed weight (SWt/S), the number seeds per boll (S/B), single seed volume (V/S) and lint yield per boll (LY/B). Finally, a single application of CCC @ 0.7 L ha-1 at the stage of DAS 90-110 days recorded optimum yield, earliness and fiber characteristics. The effects of early CCC on seed were more important than fiber characteristics.

Abstract
Pamukta mepiquat chloride (MC) ve chlormequat chloride (CCC) gibi bitki büyüme düzenleyicileri vejetatif ve generative büyüme arasındaki dengeyi oluşturmak için kullanılmaktadır. Bu çalışmada chlormequat chloride (CCC)’in farklı uygulama zamanları ve dozlarının mepiquat chloride (MC) ve control ile karşılaştırılması amaçlanmıştır. T1 (CCC’nin 3 uygulaması), T2 (MC’nin 2 uygulaması), T3 (40 ml da-1 CCC), T4 (50 ml da-1 CCC), T5 (60 ml da-1 CCC), T6 (70 ml da-1 CCC) ve kontrol ile birlikte 7 uygulama 4 tekerrürlü Tesadüf Blokları Deneme Deseninde karşılaştırılmıştır. Kütlü pamuk verimi, bitkide koza sayısı, koza ağırlığı, bitki boyu, erkencilik, çırçır randımanı, lif inceliği, tohum özgül ağırlığı, kozada tohum sayısı, tohum hacmi ve koza lif verimi yönünden uygulamalar arası farklılıklar önemli bulunmuştur. Sonuçta, ekimden sonraki 90. ve 110. günler arasında CCC’nin 70 ml da-1 dozunun verim, erkencilik ve lif kalite özellikleri yönünden en üstün değerler taşıdığı saptanmıştır. Erken dönemde uygulanan CCC uygulamasının verimin lif bileşenlerinden daha çok tohum bileşenlerini etkilediği sonucuna varılmıştır.
