| Abstract/Contents: | "A pot experiment was conducted with two wild Kentucky bluegrass (Poa pratensis) varieties to investigate their rhizome expansibility under different soil water content. The two varieties used were Yuzhong and Tianzhu, which have high and low rhizome expansibilities, respectively. Four soil water content were used: 90%~75% water holding capacity (WHC), 75%~60% WHC, 60%~45% WHC, and 45%~30% WHC. One plant was kept in each pot. The evapotranspiration rate, coverage area, tiller numbers, and shoot biomass of both varieties decreased as soil water content decreased, while rhizome number, stem internode length, maximum rhizome length, and the underground biomass, diameter, surface area, and volume of rhizomes and root/shoot ratio of the plant increased first and then decreased as soil water content decreased, reaching their respective maximum at 75%~60% WHC. At the soil water content of 90%~75% WHC, shoot expansibility reached its maximum, while at 75%~60% WHC, rhizome expansibility reached its maximum. The Yuzhong variety, which has a higher rhizome expansibility than the Tianzhu variety, needs higher soil water content than the Tianzhu variety." |
