For the study of ecophysiological characteristics of herbaceous ground covers with shade tolerance, the primary productivity was investigated and the growth characteristics and their corelationship with environmental factors were analyzed in cultivate Liriope spicata and Ajuga reptans community from Hay to October of 1986. The installation of experimental plots were split into control plot(full sunlight). 50%. 32% and 12% light intensity by randomized block design method and each plot area was 150 §³. After the transplant, to take into account the edge effect of plant population, 30 plants were selected from each plot by random sampling every 10 day. Each sampled material was divided into leaves. stems, and roots dried in a drying oven at the temperature of 80$^{circ}C$ until it had constant weight and weighed. Chlorophyll content was analyzed by Mackinney method, T-N content by Kjeldahl method, carbohydrate content by Anthron method, and growth analysis was done by Blackman method. By analyzing the dry matter production and growth characteristics of the materials cultivated on the experimental field under the condition of different treatments. the following results were obtained. 1. In each plot of Liriope spicata and Ajuga reptans, the increasing rate in the number of leaves was high at the early stage of growth and LAI was remarkably high from the last ten days of August to September, LAI of Liriope spicata under 50% light intensity and of Ajuga reptans under 32% light intensity were remarkably high. LAI of each material under 12% light intensity was very lower in the process of growth. 2. All the experimental plots of each material showed high increasing rate of standing crop from early in August to early in september. In the process of growth, Liriope spicata under 50% light intensity and Ajuaga reptans under 32% light intensity showed highly increasing rate. There existed positive relationship between standing crop and LAI with high significance. 3. Total chlorophyll contents of each material were increased in proportion to lower light intensity and their chlorophyll(a) content was 2.3 times as much as those of chlorophyll(b).
