Evaluation of Seed Cane Treatments on Sugarcane Germination in Two Planting Methods

抄録

The experiments were conducted in the glasshouse of Sugarcane Research and Development Farm, Pyinmana to evaluate the effect of seed cane treatments on sugarcane germination of K-95/84 variety in two planting methods from August-October 2015 and June-August 2016. The glasshouse experiments were conducted in 2×4 factorial arrangement in Randomized Complete Block Design (RCB) with three replications. It evaluated two different planting methods (single budded setts and three budded setts) with pre-planting treatments by using different levels of lime (0, 7.5, 15, 22.5 g l^-1), different levels of topsin fungicide (0, 0.5, 1, 1.5 g l^-1) and different degree of hot water (0, 50, 52, 54°C). Single budded setts gave the earliest and higher percentage of germination than three budded setts. Among the pre-planting treatments, the earliest and higher percentage of germination was obtained from the lowest level of lime 7.5 g l^-1 (L₁), topsin fungicide 0.5 g l^-1 (F₁) and hot water 50°C (H₁) treatments. As a combined effect of two factors, single budded setts with lime 7.5 g l^-1 (SL₁), topsin fungicide 0.5 g l^-1 (SF₁) and single budded setts with hot water 50°C (SH₁) gave maximum germination. Thus, this study highlighted that the single budded setts with lime 7.5 g l^-1, topsin fungicide 0.5 g l^-1 and hot water 50°C treatment should be used for the uniformity of germination.
