Phenols from the low-boiling fractions of pine tar oil, obtained by dry distillation of the stumps of Pinns massoniana Lamb. can be used as germicides,disinfectants and raw material for medical industry.

松焦油是从马尾松(Pinus massoniana Lamb.)伐根干馏而得,其低沸点馏分中所含的酚类化合物是有效的杀菌消毒剂和医药工业原料。为了充分合理利用这一林化资源,我们应用分馏,衍生物制备,气相色谱,红外光谱和色谱/质谱/计算机联用等分析方法,进行了化学成份的研究。共鉴定10个主要酚类化合物:苯酚(9.4%),邻-甲酚(3.7%),对-甲酚(6.8%),间-甲酚(5.4%),愈创木酚(21.2%),2,4-二甲苯酚(2.5%),3,5-二甲苯酚(4.0%),4-甲基愈创木酚(30.6%),4-乙基愈创木酚(12.1%),4-丙基愈创木酚(3.7%)等。

This paper describes the morphology, cultural characteristics and control potential of two antagnistic bacteria, Pseudomonas sp. (P751) and Bacillus cereus (BC752), both isolated from the needles of Pinus massoniana. The two bacteria were found to cause 85.7-99.3% of lysis to the conidia and ascospores of Colletotrichum gloeosprioides. Hypoderma desmazierii. and Fusarium sp.. They were inhabitive to the conidium germination of Pestalotia funerea. Botrytis cinereu and Alternaria sp.. In field trials, the control effects of the two bacteria to C. gloeosprioides. the bark rot (Eucommia ulmoides). anthracnose (Cunninghamia lanceolate), and pine red needle cast (Hypoderma desmazierii) were 52.3-59.8%, 78.9-91,9%, 15.5-52.1% and 87.3-91.4%, respectively. When P751 solution was mixed in the seeds of Masson's pine for aerial sowing, a 55.7% increase of seed germination and 21.2% increase in seedling height were obtained, compared with the nontreated check. The two bacteria were resistant to 7 fungicides and insecticides, and were safe to human and animals.

假单胞菌(代号P751)和蜡状芽孢杆菌(代号BC752)是从马尾松叶上分离的两株杆状细菌,对松赤落叶病、泡桐炭疽病、镰刀菌等5种林木病菌孢子有溶解作用,溶菌率达85.67~99.27%;对松赤枯病等3种病菌孢子萌发有抑制作用;对多种化学农药具有抗性。田间试验,防治泡桐炭疽病、松赤落叶病、杜仲环剥烂皮等5种林木病害具有不同程度的效果。经用两菌液拌种飞机播种造林试验,使马尾松叶枯病降低27.55~72.25%,出苗率有所提高。这两株杆菌对人畜基本安全。

In this paper the experimental result is reported for the first time that many buds has been induced from cultured embryo of Pinus massoniana. It is found that the buds formation needs suitable BA/NAA ratio in the tissur culture of the embryo of Pinus massoniana, that the embryo can become divided to form many buds from the cotyledon in the MS medium with BA 0.5-l.0mg/1+NAA 0.2mg/l, and these buds grow well, and that the higher the budding rate, the better the buds grow in the MS medium of BA 0.6mg/1+GA 0.2mg/l....

本文首次报道了从马尾松离体胚诱导丛生芽苗的试验结果。试验结果发现丛生芽苗的形成必需有适当浓度比例的BA和NAA,二者缺一不可。离体胚在MS+BA0.5~1.0mg/l+NAA0.2mg/l的培养基中,从子叶上分化出的丛生芽生长状况最佳。离体胚在MS+BA0.6mg+GA0.2mg的培养基中,萌芽率最高,苗的长势最佳。
