다(茶)나무 삽목(揷木)시 삽수(揷穗)의 종류(種類), 상토(床土)의 종류(種類), 생장조정제(生長調整劑) 등이 발근(發根)에 미치는 영향(影響)을 구명(究明)하고자 시험(試驗)을 수행한 결과(結果)는 다음과 같다. 1. 숙지삽(熟枝揷)보다 녹지삽(綠枝揷)에서 발근율(發根率)이 양호(良好)하며 최적(最適) 삽목시기(揷木時期)는 숙지삽(熟枝揷)의 경우 4월 10일경, 녹지삽(綠枝揷)의 경우 6월 10일경이었다. 2. 적정상토(適定床土)는 마사토(磨沙土)이며, 녹지삽(綠枝揷)과 숙지삽(熟枝揷)에서의 발근율(發根率)은 각각 71% , 87%였다. 3. 생장조정제(生長調整劑)인 Oxyberon과 Rootone의 효과(效果)는 숙지삽(熟枝揷)의 경우 대조구(對照區)에 비해 4~9%의 발근율(發根率)을 향상(向上)시켰으나 녹지소(綠枝揷)에서 는 그 효과가 미미(微微)하였다.
These experiments were conducted to promote the rooting in tea cutting bymeans of several root media, growth regulators, cutting material and cutting condition The results are summarized as follows. The rate of rooting was higher in the softwood than in the hardwood, and the best cutting season was about August 10 in the hardwood, about April 10 in the softwood. The most suitable root medium was the Masato at which the rate of rooting was 71%, 87% each in the softwood and in the hardwood. When growth regulators, such as oxyberon, rootone were sprayed upon the hardwood, the rate of rooting was promoted to 4 - 9 % better than that of no treatment. But such a good effect was not recognized significantly in the softwood.
