  • This study was carried out to obtain the basic informations on the flowering habit, pollination patterns and seed setting in Hosta plantaginea Aschers. Flowers came out in the night with white color. Almost fertilization seemed to be out by wind in early and full flowering. But bearing pods by insects and fertilization rate by wind were increased by interval of flowering and particular scent slowly decreased in after flowering. Bearing pods and seeds setting rate were $65.0\%,\;40.9\%$ per peduncle after artificial pollination, and also $33.3\%,\;24.3\%$ in natural pollination, respectively. The flowering times was all around seven to eight o'clock at night and optimum temperature for pollination was $25{\sim}28^{\circ}C$.

  • This study was carried out to develope new zoysiagrass cultivar Semil' (Registration no. 1749). Artificial crossing between the collected lines of typical Z. matrella, NM1 (collected in South Korea) and the different ecotype of Z. matrella, ASm (collected in South Korea) was made to develop a F1 hybrid plant (NM1 ${\times}$ ASm). Among the 30 progenies, (NM1 ${\times}$ ASm)-1 (Semil) showed superior performance in density rating. 'Semil' showed genetically light green color, with narrow leaf width ($2.7{\pm}0.12mm$), and low plant height ($10.3{\pm}3.7cm$), Length to lowest leaf blade of this cultivar was $1.8{\pm}0.15cm$, which may allow low mowing height upto 12 mm.

New cultivar has pink and white flower color and the shape of flower is similar to tiny ball. The number of flower petals and flowers per pot are more than those of 'POULra022' as comparison cultivar. This cultivar has low plant height without treatment of plant retardant materials, so the high quality grade ratio of potted rose is higher than that of comparison cultivar.
