Abstract
A series of rooting experiments of P. radiata needle fascicles were carried out in test tubes using peat-pumice medium to see a possibility of rooting fascicles in test tubes and, if possible, to find out whether that method can improve the rooting. Typical rooting of clones from ortets aged 3, 7, 11. 18, and over 40, respectively, was 57%, 47%, 18%, 4%, and 2%. The effect of ortet ages upon rooting of fascicle cuttings was significantly exerted in these experiments. In the older ortets these results are not as good as those often obtained in a glasshouse. Hormones tested (indolebutyric acid and abscisic acid) had no significant effect on rooting and neither did a series of fungicides tested. Needle fascicles placed in an 18 hour day at
라디아타 소나무의 엽속삽목(葉束揷木)을 시험관내(試驗管內)에서 실시(實施)하였던바 다음과 같은 결과(結果)를 얻었다. 1. 3년생(年生), 7년생(年生), 11년생(年生), 18년생(年生) 및 40여년생(餘年生)의 모수별(母樹別) 평균(平均) 발근율(發根率)은 각각(各各) 57%, 47%, 18%, 4% 및 2%이었으며 모수령(母樹令)이 증가(增加)할수록 엽속삽수(葉束揷穗)이 발근율(發根率)은 감소(減少)되었다. 2. IBA(indolebutyric acid), ABA(abscisic acid) 및 몇 가지 살균제(殺菌劑)의 처리(處理)는 발근(發根)에 별영향(別影響)을 미치지 못하였다. 3. 온도처리(溫度處理)
