| Abstract/Contents: | "With a purpose for strategies of Poa crymophila to adapt to environmental interference, we studied the growth of P. crymophila subject to varying moving frequencies and time using factorial design and in field conditions. Mowing frequencies are divided into one time, two times, and three times; and the mowing time is divided into early mowing and late mowing. The results showed that overcompensation effects occurred with all the P. crymophila in all cases, and the occurrence of overcompensation was irrelevant to moving frequencies and time. Above-ground biomass and tiller number had a significant positive correlation, P. crymophila resisted environmental interference by growing more tillers, and the resources required to produce tillers were mainly supplied by the roots. The mowing treatments of P. crymophila at different time were evaluated in respect of life history strategy. In case of early moving treatment, plants produced seeds as soon as possible to ensure their capability of production of the seeds; in case of late mowing, plants reduced the production of seeds to ensure the survival of individual plants in the coming year and taking root. Redistribution and balancing of resources in plants was the major strategy of P. crymophila to respond to interference of external environment." |
