seed counting
1.The potential seed yields of the five plants are all high by counting the values of seed yield components. The potential seed yield of Leymus chinensis is the lowest, but it can still reach to 4300 kg/km2. Harvested seed yields of Leymus chinensis, Agropyron desertorum and Elymus lanceolantus are not very high because of the factors of few reproductive branches, low seed setting percentage, seed dropping character and plant lodge, etc.
