  boletus sp
Mycelial growth and fruit-body production of an ectomycorrhizal Boletus sp.
      


The damping-off disease is one of the most important diseases of pine seedlings in nurseries. By using some chemical fungicides we have effectively controlled this disease, but the soil pollution problem must still be considered. We have found out several ectomycorrhizac, such as Suillus grcvillei (K1.) Sing, and Boletus sp., that may not only promote the growth of pine seedlings, but also protect them from infection of damping-off disease.

从油松根部分离到的外生菌根真菌:牛肝菌之一种(Boletus sp.)和厚环粘盖牛肝菌(Suillus grevillei)除对油松(Pinus tabulaeformis)幼苗猝倒病有防治作用外,还能促进幼苗生长,其显著性水平P=0.01。引起油松幼苗猝倒病的病原菌主要是立枯丝核菌(Rhizoctonia solant)和尖孢镰刀菌(Fusarium oxysporum)。在盆栽接种试验中,用牛肝菌和厚环粘盖牛肝菌接种,油松幼苗发病率比对照降低21.0—36%;在田间接种试验中,松苗发病率比对照降低16.3—25.8%。用扫描电镜对接了种的油松幼苗进行观察,发现在油松营养根表面形成密集的菌丝套,而根尖则没有。用石腊切片观察到围绕在菌根皮层细胞周围的哈蒂氏网。采用500毫升的广口瓶,盛入草炭150克、细砂50克、玉米粉9克、红糖1克、麦芽汁(1.03波美)300毫升的配方,接种牛肝菌菌丝体,置30℃,10天左右产生山蘑菇子实体。

The authors'experiments proved that ectomycorrhizae may improvethe early growth of Pinus tabulaeformis.It obviously stimulates thebiomass production of pine seedlings.The approximate percentage ofincrease is 40%. Among the mycorrhizal fungi used in our experiments,five wereselected as good ones which are capable of forming ectomycorrhizae andstimulating growth of P.tabulaeformis seedlings,i.e,Boletus sp.,suillusgrevillei,Pisolithus tinctorius,and strains obtained from the ectomycorrhizalassociation of loblolly pine and scotch pine trees. Biological analysis in greenhouse studies shows that all speciesmentioned above,whether collected from mycorrhizae association or frommature fruitbodies of fungi,can easily from ectomycorrhizae with P.tabulaeformis. The results of experiments show that by inoculum of solid pureculture,mycorrhizal fungi on roots have a great capacity to establishectomycorrhizae of coral type.The stimulation of seedling growth(including measurements of height,thickness and biomass)is proportionalto the development of mycorrhizae on it. The fact that acid soil conditions are needed for the formation ofectomycorrhizae is well documented throughout the world.Usuallyectomycorrhizae develops either weakly or not at all basic soil.But inthe authors' experiments mycorrhizae are formed both in nursery soil(pH8.6) and in greenhouse soil (with alkalinity of up to 8.9),and canimprove the growth of seedlings well.It has been proved by theseauthors that even under harsh soil conditions suitable strains cansurvive and grow significantly.This fact enlarges the area of potentialresearch into the ability of fungi to survive in adverse soil conditions. The ingredients of the nutrient medium are as follows:1) pine needle extract,2)acidic malt agar.

本试验验证了菌根化能促进油松苗木早期生长,对其生物产量有明显提高。优良菌种可使苗木干物重提高40%。试验筛选出Boletus sp.(林)、Suillusgrevillei(林)、Pisolithus tinctorius及“火炬松”、“欧洲赤松”等五个菌种在促进苗木生长方面有良好效果。经温室生物测定,不论是从菌根组织还是直接从子实体上分离到的菌种,接种后均能与油松根很好地形成菌根。用生长优良的固体纯培养物接种后,油松苗形成菌根的能力很强,多数产生茂盛的珊瑚状菌根组织,苗木的菌根化程度与其对生长的促进作用(包括干物重、高及粗生长)基本上呈正相关。在碱性及接近重碱性土壤中苗木均形成了菌根,并较好地起到促进生长作用,扩大了菌根菌抗逆性的筛选内容。试验筛选出适合菌根菌生长的培养基以及用于接种的纯培养物的载体。

室外调查结果表明,华南地区的桉树菌根虽然较贫乏,但仍发现有9种外生菌根真菌。在平均气温20℃以上,相对湿度80%以上及有相当降雨量的条件下,菌根菌子实体可大量产生;不同立地条件对外生菌根的分布有密切关系。使用5种不同的接种方法对桉树幼苗进行接种,均有较好的接种效果,其中,VA 菌根土接种,孢子菌剂接种,罐栽菌木接种及 Mycobeads 接种均有较好的效果,而且方法简单,使用方便。一年生桉树接种苗比对照株高生长平均增加14.3%;胸径平均增加13.67%;处理区一年生幼树蓄积比对照区每公顷增加5.12m~3,增加39.9%,投入与产出比为1∶15。
