Reproductive Capacity of the Genus Lespedeza (II)

싸리류(類)의 재생(再生) 능력(能力) (II)

In order to investigate reproductive capacity of genus Lespedeza 5 spp.; L. bicolor, L. maximowiczii, L. japonica var. intermedia, L. angustifolioides, and L. cyrtobotrya, their hights, diameter at the ground level, and the number of sprouts were compared with each other at the end of October during investigating years from 1970 to 1976. For measuring of invested items, 6 stocks which the one-year aged stem were cut above ground were randomly planted per square meter with six replications at the spring of 1970. After hights, diameter, and the number of sprouts were measured at the end of October every year, the stem were cut above ground at the end of November from 1970 to 1976. The results are as follows: 1. The reproductive of the stems showed statistiaclly significant differences at 1% level by species and stock ages. L. bicolor showed the best reproductive capacity of them. 2. The sprouting ability was revealed that L. maximowiczii showed the best of them. 3. The reproductive capacity of stem, diameter, and number of sprouts increased with aging of stock up to 5 years on the investigated 5 species.

싸리류(類)에 대(對)하여 매년(每年) 베어서 이용(利用)하였을 때 재생능력(再生能力)을 조사(調査)하고저 싸리, 조록싸리, 풀싸리, 늦싸리, 참싸리 종자(種子)를 1969년(年) 봄 $m^2$당(當) 4g씩 난괴법에 의하여 6반복 파종(播種)하고 당년(當年) 10월말(月末) 성적(成績)을 조사(調査)한 후(後) 지상부(地上部)를 베어주고 1970년 봄에 $m^2$당(當) 6주(株)씩 난괴법에 의(依)하여 6반복(反復) 식재(植栽)하였다. 1970년(年)부터 1976년(年)까지 10월말(月末) 간장(幹長) 근원경(根元徑) 및 맹아본수(萌芽本數)를 조사(調査)하고 매년(每年) 11월(月) 지상부(地上部)를 베어주고 근주(根株)만 남겨 놓았다. 1. 간장(幹長) 주당맹아본수(株當萌芽本數)의 재생능력(再生能力)은 품종별(品種別) 주기별(株畿別) 통계적(統計的) 유의성(有意性)을 인정(認定)할 수 있었으며 간장(幹長)의 재생능력(再生能力)은 싸리가 주당맹아본수(株當萌芽本數)은 조록싸리가 가장 좋았다. 2. 싸리류(類)를 매년(每年) 벌채(伐採)하였을 때 간장(幹長) 주당맹아본수(株當萌芽本數)의 재생능력(再生能力)의 극대치(極大値)는 주령(株齡) 5년(年)이었다.
