Abstract

Stomatal morphological characteristics (shape, density and length) were investigated for 8 ornamental woody species growing in the campus of Sangji College on Usandong, Wonju, Kangwondo. Stomata of Forsythia koreana, Syringa dialata, Zedkova serrata and Chaenomeles sinensis were classified as irregular-celled type (anomocytic), those of Vibrunum sargentii, Liriodendron tulipifera and Magnolia kobus as parallel-celled type (paracytic). For Forsythia koreana, stomatal length was not greatly changed as the leaf blade, growing larger. Number of stomata per unit leaf area was decreased, but number of stomata per single leaf was increased as the leaf blade, growing larger. For Taxus cuspidata, stomatal length was increased, but number of stomata per unit needle area was decreased as the needle, growing larger.

강원도(江原道) 원주시(原州市) 우산동(牛山洞)에 소재(所在)한 상지대학(尙志大學) 구내(構內)에 생육중(生育中)인 8종(種)의 조경수목(造景樹木)을 대상(對象)으로 기공형질(氣孔形質)(기공형(氣孔型), 밀도(密度) 및 기공장(氣孔長))을 조사(調査)하였다. 개나리, 수수꽃다리, 느티나무 및 모과나무의 기공(氣孔)은 irregular-celled type(anomocytic)이며, 백당나무, 튜울립나무 및 목련의 기공(氣孔)은 parallel-celled type(paracytic)이었다. 개나리의 경우, 엽신장(葉伸長)에 따른 기공장(氣孔長)의 변화(變化)는 거의 없었고, 단위엽면적당(單位葉面積當) 기공수(氣孔數)는 크게 감소(減少)했으며, 개체엽당(個體葉當) 기공수(氣孔數)는 증가(增加)하였다. 주목의 경우, 침엽신장(針葉伸長)에 따라 기공장(氣孔長)은 계속 증가(增加)했으며, 단위엽면적당(單位葉面積當) 기공수(氣孔數)는 감소(減少)하였다.
