Plant growth regulators such as mepiquat chloride (MC) and chlormequat (CCC) are used to establish the balance between vegetative generative in cotton. This study was conducted compare different doses application time of CCC with MC un-treatment (control). The seven treatments including control (non-treatment), T1 (three sprays chloride), T2 (two T3 (0.4 L ha-1 CCC), T4 (0.5 T5 (0.6 CCC) T6 (0....

Alternate-1 and alternate-2 orientation of chromosomes, as well as the two types of adjacent orientation, were observed cytologically in the ring configurations of three reciprocal translocation heterozygotes of Gossypium hirsutum L. The observations indicate that the two types of alternate orientation should be characteristic of ring-forming translocations.
