Effects of plug size on grow seedlings of five Carex species

This study was carried out to select appropriate plastic tray for C.breviculmis, C. giraldiana, C. lanceolata, C. humilis var. nana and C. pediformi seedlings growing. Six important indexes including germination initial time, germination duration time, germination rate, plant height, leaf number and fresh weight of five Carex spices were compared and analyzed. The result was as follows: the plastic trays of 128 cells and 105 cells were more appropriate for C. breviculmis, C. giraldiana; the trays of 105 cells were appropriate for C. lanceolata; the trays of 288 cells were appropriate for C. humilis var. nana and C. pediformis.
