Germination and survival capacity of cassava cuttings under controlled moisture and field conditions in Thailand
1988
Limsila, J.
Results showed high germination percentage (82.5-100%) of all clones/varieties under field condition. However, differences in germination percentage were highly significant among them. The highly significant survival percentage among clones/varieties observed three months after planting ranged from 27.2 to 92.5 percent with eight clones, Rayong 1 and Rayong 3 having survival percentage of more than 80 percent. Dry matter content and specific gravity of stem cuttings had significant positive correlation with percent survival while specific gravity had significant positive correlation with percent germination. In the experiment under controlled initial soil moisture content at field capacity (FC), 75, and 50 percent FC, there was a highly significant interaction between moisture level and cassava clones/varieties on percent germination and on percent survival. Eighteen of the 23 clones/varieties were not affected by soil moisture levels while five had significantly lower percent germination when planted under reduced soil moisture level. An opposite result was observed in percent survival where the significant reduction in percent survival was noted at a higher (FC) moisture level.
