| Abstract/Contents: | "Effect of growth regulators on the tuberization of purple nutsedge were evaluated in a phytotron, maintained at 25°C to 20° C (day and night, respectively) under natural light intensity and photoperiod. Kinetin treatment increased tuber numbers of purple nutsedge by an average of 31.7% as compared with the untreated control. The highest increase, about 45%, was obtained with kinetin treatment at 10-4M. Tuber numbers increased as the levels of kinetin increased from 10-6M to 10-4M. However, kinetin treatment retarded shoot development per plant so that they showed much fewer shoots than the untreated control. The total dry weight including shoots and tubers in both kinetin treatment and the untreated control showed no significant difference, indicating that the total growth of purple nutsedge might not be affected and a growth regulator like kinetin modifies the process of its growth. Other growth regulators such as TIBA, B-9 and CCC had no significant effect on the growth of purple nutsedge compared with kinetin. Induced effects of kinetin on tuberization applied alone were nullified when combined with various levels of GA, indicating that GA inhibited the kinetin-induced tuberization." |
