Abstract

Corm type correlates with corm size, which affects longevity and early growth in the field. Seed storage after harvesting is important to preserve viability and vigor. This study was conducted to determine the correlation between the corm type and storage period on corm deterioration, storage, vigor, and growth in the field. A factorial randomized complete block design (RCBD) with three replications was arranged, with the corm size (i.e., corm and cormels) and the storage period (i.e., 0, 2, 4, and 6 weeks). Corms undergo color changes faster than cormels do. The weight and diameter decreased by more than 10–30% after 4 weeks, while the length decreased by more than 10% after 6 weeks, and even the hardness decreased by 50% compared to that at 0 weeks. Corms were stored for 6 weeks, when the weight loss was lower than that of cormels. The corm sprouted after 2 weeks of storage. Corm resulted in a higher sprouting percentage than cormels. The corm type did not have a significant effect on growth vigor, but corm resulted in higher growth vigor than cormels after storage. The storage period leads to growth vigor loss. Weight, length, and diameter loss were positively correlated with sprouting and negatively correlated with hardness and growth vigor. This research recommends that the storage period of taro tubers before planting should be less than six weeks to optimize growth in the field.
芋头球茎类型及贮藏对田间形态生理退化及早期生长的影响
球茎类型与球茎大小相关,影响田间寿命和早期生长。种子采后贮藏对保持种子活力和活力具有重要意义。本研究旨在确定不同球茎类型与贮藏期对田间球茎腐烂、贮藏、活力和生长的相关性。采用因子随机完全区组设计(RCBD),按球茎大小(即球茎和球茎)和贮藏期(即0、2、4、6周)设计3个重复。球茎的颜色变化比刚毛快。4周后,重量和直径下降了10-30%以上,6周后,长度下降了10%以上,硬度也比0周时下降了50%以上。球茎贮藏6周,此时的减重率低于大鼠。贮藏2周后球茎发芽。球茎的出芽率高于球茎。球茎类型对生长活力无显著影响,但贮藏后球茎的生长活力高于球茎。贮藏期导致生长活力损失。重量、长度和直径损失与出芽呈正相关,与硬度和生长活力呈负相关。本研究建议,芋头块茎在种植前的储藏期应少于6周,以优化田间生长。
