旱棚条件下燕麦品种的耐旱性评价

Evaluation on Drought Tolerance of Oat Varieties under Control of Rain Protection Shed

选用6个不同类型的燕麦品种,在旱棚条件下通过水、旱处理对比进行耐旱性鉴定。结果表明:干旱处理能够反映燕麦品种耐旱能力的绝对量,非干旱处理能够反映燕麦品种丰产性的绝对量;坝莜3号、冀张莜4号、坝莜1号、坝燕4号和坝莜9号均具有较强的耐旱性,冀张莜4号、坝燕4号、坝莜9号和坝莜6号对水分反应敏感,具有较好的丰产性,其中冀张莜4号既耐旱又喜水。此外,水旱比值能够反映燕麦品种对水分的敏感性和丰产性,在抗旱性评价中同样具有重要意义。

The drought tolerance of six oat varieties under control of rain protection shed was identified. The results showed that the drought treatment could reflect the absolute drought tolerance ability, and the non-drought treatment could reflect the absolute high yield. Bayou No. 3, Jizhangyou No. 4, Bayou No. 1, Bayan No. 4 and Bayou No. 9 had strong drought tolerance. Jizhangyou No. 4, Bayan No. 4, Bayou No. 9 and Bayou No. 6 were sensitive to water with high yield. Jizhangyou No. 4 was tolerant to drought and sensitive to water. In addition, the ratio of water to drought could reflect the sensitivity to water and high yield, which was important in drought resistance evaluation.
