상사화류의 분류 및 품종 개발을 위해서 상사화속 22종류의 개화와 출엽 유형 및 특성을 조사하였다. 개화시기는 7~8월에 1종류, 8월에 12종류, 9월에 개화하는 것이 9종류였다. 꽃의 모양은 L. radiata 형이 9종류, L. squamigera 형이 7종류, 중간형이 7종류이었다. 꽃의 색깔은 적색계열과 분홍색 계열이 각각 3종류, 백색계열이 7종류, 황색 계열이 4종류, 주황색계열이 3종류, 자색 계열이 2종류였다. 임성은 좋은 것이 10종류, 조금 되는 것이 2종류였었다. 화분립(pollen grain)의 평균 길이는 48.53~88.62μm 였으며, 평균 폭은 22.87~33.67μm였다. 출엽형은 춘기출엽형이 11종류, 추기출엽형이 10종류였다. 잎의 Hunter value은 L*값이 31.6~45.2, a*값은 -6.74~-17.46, b*값은 6.19~21.89의 범위에 있었다. 잎폭은 0.90~2.35cm였으며, 모양은 대부분 장방형이었다. 표피세포 길이는 0.33~0.75mm였으며, 폭은 38.53~90.00μm였다. 기공은 대부분 뒷면에 많이 분포되어 있었다. 기공의 길이는 67.12~104.89μm였으며, 폭은 14.90~71.52μm였다.
This study was conducted to examine the pattern and characteristics of flowering and leaf emergence for twenty two kinds of the genus of Lycoris sp. One species of Lycoris was flowered on July to August, twelve species on August, and nine species on September. Shape of flowers were as follows : Nine species belong to L. radiara-shaped flower, seven species L. squamigera-shaped flower, and seven species the intermediate type. Flower color of three kind were an order of descent red and pink. seven kind white, four kind yellow, three kind orange, and two kind purple colors. Ten Lycoris species were good fertile, and two kinds were poor fertile. The average length of pollen grain was ranged from 48.53 to 88.62μm, and the width from 22.87 to 33.67μm. Eleven kinds were spring-leaf emergence type, and ten kind 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 was oblong. The length of epidermal cells was 0.33 to 0.75mm, and the width was 38.53 to 90.00μm. Most of stomata were distributed in the back side of leaves. The length of stomata was ranged from 67.12 to 104.89μm, and its width was from 14.90 to 71.52μm.
