黑龙江省夏季气温急剧上升，对本地和引进的冷季型草坪草都造成了严重的危害。本研究的目的是比较生理反应的季节性热应力和草坪性能之间的本地和引进的商业早熟禾加入。中国早熟禾属（Poa）3个乡土种（即，P. pratensis、P. sibirica和P. sphondylodes）和三个美国肯塔基州早熟禾品种（即.“午夜”、“月光”和“蓝筹”）于2017年和2018年在田间条件下进行了评价。所有加入表现出独特的特点和相当大的季节性差异，在响应温度。然而，在早春和秋季，所有加入的性能基本相似。在夏季，天然草地早熟禾在品质、覆盖度、颜色强度、生长速率、渗透调节物质、活性氧和抗氧化物质等性状上与“午夜”、“月光”和“蓝筹”表现相似。在黑龙江省特定的气候条件下，草地早熟禾可作为一种新的草坪资源进行进一步的改良和应用;而软枝早熟禾可用于修复受损的环境或替代季节性绿化。
Rapid rise in temperature in summer causes severe injury to cool-season turfgrass of both native species and introduced ones in Heilongjiang of Northeast China. The objectives of this study were to compare physiological responses to seasonal heat stresses and turf performances between native and introduced commercial Poa accessions. Three Chinese native Poa species (i.e., P. pratensis, P. sibirica and P. sphondylodes) and three USA Kentucky bluegrass cultivars (ie. ‘Midnight’, ‘Moonlight’ and ‘BlueChip’) were evaluated under field conditions in 2017 and 2018. All accessions showed unique characteristics and considerable seasonal differences in response to temperatures. However, performances over all accessions were largely similar in early spring and autumn. In summer, native P. pratensis performed similar to ‘Midnight’, ‘Moonlight’ or ‘BlueChip’, with respect to such traits or parameters as quality, coverage, color intensity, growth rate, osmolytes, ROS and anti-oxidant production. Native P. pratensis could be used as a new turf resource for further improvement and application under the specific climatic conditions in Heilongjiang; native P. sphondylodes may be used in repairing damaged environments or for alternative seasonal greenness.
