结缕草

Zoysia japonica is a perennial, short bunch grass,which has widely adaptability and strong resistance.It distributes in 11 provinces in China.

结缕草是多年生低矮草本植物，在我国11个省份有分布，具有生态幅宽、抗性强等优良特性。

Results showed that leaf blades, coverage and density of wild zoysia higher than those of tifgreen, but the chlorophyⅡ content was lower.

结果表明：野生结缕草的叶片宽度、盖度、密度大于杂交狗牙根，但相同鲜叶重的叶绿素含量小于杂交狗牙根。

During 1959-1962, the author investigated and observed the influences of biological char-acters, external conditions, management methods on the gardening effect of three lawn grasses Buchloe dactyloides Nutt.

本文根据四年(1959—1962)的试验及观察结果，分析讨论了野牛草、结缕草及羊胡子草三种北京地区草坪植物的绿化效果。绿色持久性、再生力、与杂草竞争能力等生物学特性，土壤、地形及荫蔽等环境条件，以及栽培管理措施，均能影响着绿化效果。

Treating Z macrostachya seeds with NaOH solution was simple and feasible with highest germination rate.

结论］NaOH溶液处理大穗结缕草种子，既简便可行，种子发芽率又最高。

The results show that Poaceae formed monophyletic group comprised of four clades, cladeA, B, C, D.

结果显示，ITS序列和trnL-F序列将结缕草族及近缘属植物明显地分为4个姐妹分支A、B、C、D。

Through the study, we found that costal zones of Perotis markedly wider than Tragus and Zoysia; There are papillaes and not short cells over the veins in Tragus.

利用光学显微镜对结缕草族及其近缘属代表植物的叶表皮微形态、颖果以及硅细胞形态进行了观察研究。

The Perennial ryegrass, Tall fescue and Red fescue have the largest seed germination rate under the 8 grades NaCl concentration stress. With the concentration increasing, the seed germination of turfgrass sharply decreased. Most of the turfgrass seeds couldn germinate under the NaC1 stress which concentration was above 0.1%, besides the Zoysia, Alkali grass and Creeping bentgrass got a good germination rate.

利用8个梯度（0％，0.2％，0.4％，0.6％，0.8％，1.0％，1.2％，1.4％）的NaCl胁迫处理试验发现，低盐浓度下（培养液〈=0.2％NaCl）草种发芽率以多年生黑麦草、高羊茅最高；随着盐浓度的增加，各草种发芽率迅速下降，当盐浓度达到1.0％时，大部分草种不能发芽或发芽很少，只有结缕草、碱茅及匍匐翦股颖等草种有较好的发芽表现。

The results showed that soil copper contamination did not significantly affect the leaf growth of Bermuda grass and its influence on root biomass and leaf chlorophyll content in Bermuda grass were also less than that in zoysiagrass.

结果表明：铜污染处理对狗牙根草坪的地上部分叶片生长量的影响不显著，对根系生长量和叶绿素含量的影响也明显小于结缕草；铜污染处理未引起冷季型草坪的叶绿素含量的下降，对高羊茅草坪的密度影响不显著，对叶片生长量的影响也明显小于草地早熟禾和多年生黑麦草，而草地早熟禾虽然叶片生长受到了严重的抑制，但根系生长未受到显著影响，也表现出了对土壤铜污染的一定的耐性。

Two warm-season turfgrasses, including Bermuda grass and zoysiagrass, and three cool-season turfgrasses, including tall fescue, Kentucky bluegrass and perennial ryegrass were selected to study their growth responses under the simulated soil copper contamination conditions.

通过模拟土壤铜污染处理，对2种暖季型（狗牙根Cynodon dactylon、结缕草Zoysia matrella）和3种冷季型（高羊茅Festuca arundinacea、草地早熟禾Poa pratensis、多年生黑麦草Lolium perenne）草坪草种的生长指标进行了分析。

The results show that the net photosynthesis rate diurnal variation curves of kentucky bluegrass and japanese lawngrass were double-peaked, while the curve of tall fescue and creeping bentgrass were three-peaked.

结果表明：草地早熟禾和日本结缕草的净光合速率日变化曲线为双峰型，而高羊茅和匍匐翦股颖为3峰型。
