Abstract
- This study was conducted to examine the pattern and characteristics of flowering and leaf emergence fortwenty two kinds of the genus of Lycorissp. One species of Lycoriswas flowered on July to August, twelve species onAugust, and nine species on September. Shape of flowers were as follows : Nine species belong to L. radiata-shapedflower, seven species L. squamigera-shaped flower, and seven species the intermediate type. Flower color of three kindwere an order of descent red and pink, seven kind white, four kind yellow, three kind orange, and two kind purple colors.Ten Lycorisspecies were good fertile, and two kinds were poor fertile. The average length of pollen grain was rangedfrom 48.53 to 88.62㎛, and the width from 22.87 to 33.67㎛. Eleven kinds were spring-leaf emergence type, and tenkind autumn-leaf emergence types. Hunter values in leaves were as follows : L* value was ranged from 31.6 to 45.2; a*values from -6.74 to -17.46; b* values from 6.19 to 21.89. Leaf width was ranged from 0.90 to 2.35cm, and its shape wasoblong. The length of epidermal cells was 0.33 to 0.75㎜, and the width was 38.53 to 90.00㎛. Most of stomata weredistributed in the back side of leaves. The length of stomata was ranged from 67.12 to 104.89㎛, and its width was from14.90 to 71.52㎛.Key words - Leaf shapes, Intermediate types, Pollen grain, Stomata
