| Soaking improved germination percentage, the best treatment being ethrel, followed by water soaking. Germination rate was also improved by soaking: cuttings soaked in ethrel and water reached 50 per cent germination first while for ED99, there were no significant differences among the 4 soaking treatments. IBA and 2,4-D had no effect on germination per se, but treatments have benefited from water absorption. There was no significant difference in water absorption among treatments, this being a function of volume and position of cuttings, with top cuttings having a better absorptive power. Change in sugar content of cuttings could not be correlated to soaking treatments and germination on the basis of the data obtained. Growth in ethrel-soaked treatment slowed down and was caught up by the control sixty-nine days after planting, while water-soaked treatment maintained its advantage of earlier germination. At this stage, there was no difference in height between top and bottom cuttings. Growth parameters (leaf area and tillering were not influenced by soaking; variety S17 and bottom cuttings had a greater leaf area and better tillering. The above results were obtained in the field experiment; a similar trial conducted in the glasshouse gave the same results for germination. As regards growth, it was found that treatments had no effect and this was attributed to high temperature prevailing in the glasshouse. Overall results indicate that soaking in ethrel and water significantly improved germination percentage and rate. Soaking in water had a beneficial effect on growth while ethrel had an adverse effect of growth. | |
