馬鈴薯種薯供應試驗(第三報)馬鈴薯種薯貯藏溫度對種薯價值之研究

Abstract

1. 為探求本省生產之農林一號馬鈴薯種薯之貯藏方法，使用5℃，15℃及25℃冷藏6個月後種植檢定其生產情形。 2. 貯藏後取出時之發芽情形以5℃區之情形最佳，其芽少而短，芽數亦少。 3. 種植後1個月時及2個月時調查生長情形亦以5℃區為最佳。 4. 單為面積產量亦以5℃區為最高。並各處理間之產量差異為極顯著。 5. 用上述之三種溫度貯藏種薯應用5℃為理想。 1. A storage experiment was made to study the best temperature for storage seed tubers of No-lin No. 1, potato produced in Taiwan. The tubers were stored under 5°C, 15°C and 25°C for six months. The condition of tubers at the end storage period was recorded plant growth and yield from tubers stored under different temperature were compared, the result were summarized as follows. 2. The condition of the tubers under 5°C was the best, it has the least number of germinated buds and it’s sprout remained small. 3. Tubers stored under 5°C gave the best plant growth two months after planting. 4. Significant difference in yield per unit area was observed between tubers stored under different temperature, tubers stored under 5°C gave the highest yield. 5 It was concluded that 5°C was the best temperature for storage on No-lin No. 1, potato seed tubers produced in Taiwan.
