박문한,이구연,박유헌,문홍규,김원우 한국산림과학회 1988 한국산림과학회지 Vol.77 No.1

For the development of the vegetative propagation by cuttings with superior phenotypes of Quercus acutissima, the effect of media containing various rooting substances(IBA, NAA, IAA, Sucrose, Captan and Talc.), the difference between sprout and normal branches of seedling, the position effect of cutting, seasonal variation, the difference between out-door seedling and greenhouse seedling, ortet age effect, upon the rootability and the development of root system using 1 to 3-year-old seedlings have been investigated. The obtained results were as follows 1. Survival., rooting, primary root number and primary root length of cuttings showed significant differences among the media containing rooting substances. 2. Sprout showed better rooting ability than the normal t~ranch of seedling and the number of the primary roots was abundant, too. 3. Rooting eras better on V/PL and P/V media bed than any other tested ones when media without growth substances were experimented while callus ball formation was vigorous under the part of cuttings on the medium containing perlite. 4. Basal part had slightly better rooting ability than top part with apical bud for cutting`s position. 5. Rootability was varied greatly by seasons of cutting collection. The best rooting was observed in the mid-June with semi-hard wood, after first growing season. 6. Greenhouse seedlings hadmore numbers of the primary root and rooted more readily than nurserybed seedlings. 7. The most significant difference in rooting ability was observed between the ortet ages, 58.3% and 84.4% for 1 and 3 year orter, respectively.

Pinus thunbergii × P . massoniana F1 교잡종 (交雜種) 유묘의 (幼苗) 특성

박문한,전계상,윤양 ( Mun Han Park,Gae Sang Jhun,Yang Youn ) 한국산림과학회 1985 한국산림과학회지 Vol.69 No.1

Pinus thunbergii × P, massoniana F₁ hybrids were made by pollinating 15 years old Japanese black pine (P. thunbergii) with Masson pine (P. massoniana) pollen, air-shipped from Taiwan. The crossability between two species were observed. Seedling height, morphological characteristics, and the composition of plhenolic compounds of these hybrids and the open-pollinated progenies of P. thunbergii were investigated. The results of the observation were as follows; 1) Number of the hybrid seeds per cone was 2.3, while open-pollinated Japanese black pine produced 26 seeds per cone. 2) All hybrid seedlings outgrew P. thunbergii, averaging 151% of mean height of Japanese black pine seedlings. The growth of hybrids was much variable, ranging from 120% to 208% of mean height of the open-pollinated progenies of P. thunbergii. 3) With regard to needle characteristics, the hybrid needles were longer and softer than those of P. thunbergii. The color of hybrid needles showed yellowish green. The positions of resin ducts in P. thunbergii observed medial, while those of hybrids showed medial and external. 4) No large difference in phenolic compound composition between hybrid and P. thunbergii was found, but phenolic compound of unknown 4 and 6 were observed only in hybrid. Further intensive work is recommended in this area.

리기테다 수형목 (秀型木) 차대들의 내한성에 (耐寒性) 대한 선발

박문한,손성인,전계상 ( Mun Han Park,Sung In Sohn,Gae Sang Jhun ) 한국산림과학회 1986 한국산림과학회지 Vol.75 No.1

One-year-old seedlings of open-pollinated progenies of pitch-loblolly hybrid pine plus trees were selected for cold-hardiness during cold winter of 1983-1984. Survived trees were planted in three locations. Two years later, the ratio of cold-damaged trees and 3rd year heights were recorded. The ratio of the, cold-damage trees among screened progenies were 5.6% in Kyunggi and 22.6% in Chungnam, while 9.3% and 43.3%, respectively, in unscreened control plot. Severely damaged families at one-year-old seedling stage also suffered heavy cold damage after two years. Not much differences were observed between families in 3rd year height.

왜성사과나무의 고밀식재배법은 우리나라 농가의 부족한 노동력 문제를 해결할 수 있는 새로운 사과나무 재배법으로 각광받고 있다. 그러나 왜성사과나무로 개식하는데 따른 사전 지식 없이 개식을 하게 되면, 뜻하지 않은 개식 장해에 의해 피해를 입을 수 있다. 특히 농산물 수입의 전면 개방화를 앞두고, 따라서 철저한 준비에 이은 왜성사과나무 조성으로 수입과일에 대한 경쟁력을 갖추도록 하여야 할 것이다.
