Structures of the dormancy modules on Puccinellia tenui f lora populations in alkalinized meadow in the Songnen Plains of China

摘要：

Puccinellina tenui f lora, a perennial grass of tuft, and forms larger area monodominant communities in alkali‐ patches with loss of surface soil.Its economic value is considerable greater because of better capability of tolerance to the salt and alkali stress in alkalinized meadow in the Songnen Plains of China (Zheng and Li, 1993).There were some reports about the bio‐chemical mechanism, bio‐ecological characteristics, the characteristics of production, etc ( Yang and Zhu, 1994 ).However, the researches of the dormancy modules of P.tenui f lora populations have never been reported.Structures the dormancy modules were compared and analyzed on P.tenui f lora populations in two pastures for haying and grazing in the Songnen Plains, which may not only accumulate science materials on population ecology of tuff clone plant but also provide scientific evidence to suitable utilization of.alkalinized meadow.
