Changeable features of several physiological parameters of seed development process of Puccinellia tenuiflora cv. Tongde

  • Six methods were used to measure moisture content, physiological and biochemical parameters of seed quality of Puccinellia tenuiflora cv. Tongde in the seed development process. The results of this study indicated that the loss rate of seed moisture content showed a firstly quick and then slow trend and the seeds became mature when they developed for 26 days after peak anthensis with 27.85% of seed moisture content. The seed soluble sugar content of P.tenuiflora cv. Tongde decreased gradually with the seed development, on the contrary, the starch content increased. The maximum IAA content in the development process of P.tenuiflora cv. Tongde seeds was firstly appeared and the maximum was finally appeared. This study suggested that the seed vigor continually increased with seed development, peaking at 26 days after peak anthensis.
