To compare the vitality of street trees in Seoul and Suwon, electrical resistance of cambial area (ERCA) were measured in each trees. Examined areas were 2 localities each of Seoul and Suwon. In both areas, total 611 streetl trees of 2 species, Ginkgo biloba L. and Salix pseudo-lasiogyne Lev., were examined. ERCA measuring was accomplished from August 13, 1983 to September 1, 1983, under the uniform conditions. A field ohmmeter (Shigometer, model OZ-67) was used for the measurement of ERCA. There was significant (p<0.01) correlation between ERCA and the tree diameter at breast height (DBH). In all trees, ERCA decreased with the increase of DBH. The ERCA of trees in Seoul was significantly (p(0.05 in Ginkgo biloba, and p<0.01 in Salix pseudo- lasiogyne) higher than that of Suwon. However, there was no significant difference in ERCA between foootway side and driveway side of each tree.

Red dye solution was injected into zelkova trees with gravity flow type trunk-injectionmethod to investigate the effects of the injection wound size and tree crown condition on theinjection efficiency. Injection speed of widely used injection wound in Korea, 10 mm diameterwas compared with that of 5 mm. Tested levels of the crown were intact, half-loss, and doublequarter-loss. More than 30% of the dye solution was absorbed into the trunk of almost allzelkova trees 4 hours after injection. After 7 hours, whole volume of the dye solution wasabsorbed up in 7 trees. Absorption of the dye solution in all trees but one was accomplishedwithin less than 48 hours from the injection. Leaves turn red and most injected-trees showedred color in their crown regardless of the treatments. In statistical analyses, neither the diameterof injection wound nor the crown condition showed any significant influence on the time for entire absorption. The number of trees of which leaves turning red did not show any statisticaldifference among the treatments, either. In addition, distribution of dye solution in the stem wasalmost same in all treatments. These results could be concluded that there is no difference ininjection efficiency between the diameters of injection wounds. Therefore, use of 5 mm injectionwound rather than 10 mm in trunk-injection is better idea to help self-healing of the tree. 주입구멍의 크기와 수관 상태에 따른 약액의 수간주입 속도를 알아보고자 주입구멍의 지름을 5mm와10mm로 하고 수관을 온전, 절반 제거, 1/4씩 두 곳 제거 등 세 수준으로 구분하여 식용색소 적색3호수용액을 수간주입하고 일정 시간별로 주입량을 측정하였다. 수간주입 4시간 뒤에 대부분의 느티나무에서 약액이 30% 이상 흡수된 상태였으며, 7시간 후에서는 7그루에서 모든 약액이 흡수된 것을 확인하였다. 48시간 후에는 처리 조건과 방법에 관계없이 한 그루를 제외한 모든 개체에서 주입액이 완전흡수되었다. 주입구멍의 크기나 수관의 상태 등은 수간주입 속도와 통계적 유의성이 없었다. 주간에서 움트는잔가지의 잎들은 수간주입 후 24시간에 붉은색을 나타내기 시작하였으며, 48시간 후에는 수관의 잎들도 엽육조직이 붉게 변하여 수관도 붉은 색을 보였다. 수관이 변색된 나무의 수도 처리 내용 간에 통계적 유의차가 없었다. 줄기 단면 관찰에서도 주입구멍의 크기나 수관 상태 간에 적색주입액의 분포 차이가 없었다. 본 연구의 결과로부터 주입구멍의 크기나 수관의 엽량은 수간주입의 효율에 영향을 미치지않음이 확인되었다. 따라서 큰 상처를 남기는 지름 10mm 주입구멍보다는 지름 5mm 주입구멍을 사용하는 것이 나무의 자가치유를 도와주는 올바른 수간주입법이라고 할 수 있다.

여러수준의 산성비가 고추씨의 발아율 및 모 생육에 미치는 영향

In the experiment to determine the effect of simulated acid rain(SAR) of various pH on the germination rate and the growth of Capsicum annum cv. Komyung(red pepper), the low pH of SAR accerlated the grrmination of the seeds even though the effect of pH was not statistically significant. After 10 days of SAR treatment, soil pH dropped to a great extent. There was, however, little change in tap water treatment(control) . In SAR of low pH(2.5, 3.0), soil pH was lower than that of control after 10 days of treatment, but, it became lower after 20 days of treatment in high pH(3.5, 4.0, 4.5) SAR. Visible symptoms caused by SAR were white spot and marginal necrosis of the leaves. The lower the pH of SAR, the more the number of spots per leaf and the number of spotted leaves. Decrease in pH of SAR increased the severity of damage and reduced the period that the first visible symptom appeared. Effect of SAR on the DW/FW ratio of red pepper seedlings was not significant. Either in dry weight or fresh weight, root/shoot ratio of the seedlings, however, varied significantly by the pH of SAR. That is to say, root growth of SAR-treated seedlings was inhibited compared to that of tap water-treated seedlings.

옥시테트라사이크린 ( OTC ) 수간주입 상처에 대한 밤나무의 반응

Chestnut(Castanea crenata) were trunk-injected by two methods to check the changes around the injection wound. In September 1993, high concentration of oxytetracycline(OTC) was injected through the injection wound of 1㎝ diameter and low concentration of OTC through 0.5㎝ diameter. Trunk diameter of injected trees ranged from 10㎝ to 20㎝. All trees were in their vigorous conditions. Tree reaction was examined in June, 1994. None of them showed any sign of decay by the time. However, under the bark, sapwood was remarkably discolored. But, more severe discoloration was found in l㎝-injection wound than in 0.5㎝ one. Sapwood of some trees split from the injection wound, and the split was longer in l㎝-injection wounded trees than in 0.5㎝ trees. From the split, callus grew out and the split was closing. In this kind of trunk injection, the damage was more severe in l㎝-injection wound than in 0.5㎝-injection wound.

나무의사 제도 법제화에 따른 식물병리학회의 역할

차병진,Cha, Byeongjin 한국식물병리학회 2017 식물병연구 Vol.23 No.3

In December of 2016, 'The Forest Protection Act' was amended partly in The National Assembly and the socalled 'Tree Doctor Act' was promulgated. Tree Doctor Act will be enforced from June 28, 2018. Under the new Act, none other than 'Tree Hospital' can do disease and pest management work for trees in public living space. The only exclusive qualification for tree hospital is a 'Tree Doctor', the government registered license which is newly established by the Act. To become a tree doctor, he/she must complete the tree doctor training courses in the designated 'Tree Doctor Academy' and pass the qualification test. Currently, Korea Forest Service is drafting the enforcement ordinances and regulations for the implement of Tree Doctor Act. When taking into consideration that the most fundamental and important discipline of the plant and tree health care is the plant pathology, and that the tree health care is a promising business for young plant pathology people, Korean Society of Plant Pathology is ought to be actively involved in the preparation of the enforcement ordinances and regulations, and help the early establishment of the new tree health care system in living spaces of Korea. 2016년 12월에 산림보호법 중 일부가 개정되어 이른바 '나무의사법'이 공포되었으며, 이 법은 2018년 6월 28일부터 시행될 예정이다. 새로운 법안에서는 나무의사 자격 소지자에 한하여 나무병원을 개업할 수 있고, 나무병원만이 생활권 공공분야의 수목병해충 관리를 할 수 있도록 규정하고 있으며, 그에 따라 '나무의사'라는 국가공인자격이 신설되었다. 나무의사가 되기 위해서는 지정된 양성과정을 이수하고 시험을 통과하여야 한다. 현재 산림청에서는 이 법의 시행을 위하여 구체적 시행방안을 포함하는 시행령과 시행규칙 등을 만들고 있다. 수목진료 및 건강관리에서 가장 핵심적인 부분이 식물병리학이라는 사실을 감안할 때, 그리고 식물병리학을 공부하는 학생들의 사회진출을 위하여 식물병리학회는 새로운 수목진료체계가 정착될 수 있도록 나무의사 양성기관의 교육과정 개발 및 나무의사 선발시험계획 수립 등에 적극적으로 관여하여야 할 것으로 생각한다.
