Germination characteristics among different sheepgrass (Leymus chinensis) germplasm during the seed development and after-ripening stages.

ABSTRACT: Sheepgrass (Leymus chinensis (Trin.) Tzvel) is an important forage grass in the Eurasian steppe. However, little information is available concerning its seed morphological features and germination characteristics during seed development and after-ripening among different germplasm. To clarify the appropriate seed harvest time and the effects of germplasm, seed development and after-ripening on seed germination, 20 germplasm of sheepgrass were selected. Moreover, the seed morphological and physical changes as well as the seed germination and dormancy characteristics of sheepgrass during seed development stages were analyzed using a seven-d gradient of day after pollination (DAP). The results indicated that the seed water content decreased significantly during 35-42 DAP and that the h
