Resistance And Summer Performance Of 5 Agrostis Stolonifera Varieties (Lines) In Changsha

There are 5 agrostis stolonifera varieties(lines) used widely in Changsha and other transitional areas,which researched in this experiment through plot trial.Each material biological characteristic such as the extra morphology, above ground biomass, below ground biomass, turf quality and resistance had been compared.The main results are as follows:Through 5 agrostis stolonifera varieties(lines) external morphology were observed, there is a big difference between the various grasses on the external morphology difference: intermediate section Creep bent grass T-l shorter length, inter node diameter medium thickness, the smallest blade of grass layer low, the quality of the best lawn appearance. Inter nodes length Acrostic stolonifera L.Yuexuan No.l smallest and most detailed inter node, leaf fine, outstanding quality lawn appearance.091 and 093 long stem node, node diameter coarse, medium quality appearance, the appearance of superior quality which 093. Anshan due to inter nodes longest, widest blade of grass in the five worst turf quality.Lawn turf traits, tested 5 agrostis stolonifera varieties(lines) summering grasses are present difficult problems. In ornamental lawns, recreation sports turf lawns and comprehensive assessment of the three types of lawn, Creep bent grass T-l> Acrostic stolonifera L.Yuexuan No.l> Anshan> 093> 091. Where in the resistance is due to Acrostic stolonifera L. Yuexuan No.l worst 5 varieties(lines), and other properties and Creep bent grass T-l rather, it scores in the three types of lawn were lower than Creep bent grass T-l.Resistance aspects studies showed that under drought stress conditions,5 agrostis stolonifera varieties(lines) T-l> Acrostic stolonifera L. Yuexuan No.l> 093> 091> Anshan. Under conditions of high temperature stress, the order of five grass Acrostic stolonifera L Yuexuan No.l> Creep bent grass T-l> Anshan> 093> 091. In the high temperature and drought stress double,5 agrostis stolonifera varieties(lines) of Acrostic stolonifera L. YuexuanNo.l> Creep bent grass T-l> Anshan> 091> 093.Is represented by the conductivity cell permeability, through the observation of five grass species,5 agrostis stolonifera varieties(lines) of Acrostic stolonifera L. CV.Yuexuan No.1> Creep bent grass T-1> 091> 093> Anshan.
