金属离子对蒙古口蘑菌体及胞外多糖的影响

研究了5种金属离子Fe2＋、Zn2＋、ca2＋、Cu2＋、Mg2＋对蒙古口蘑的茵体生长及胞外多糖的影响。结果表明,在培养基中添加5种金属离子Fe2＋、zn2＋、ca2＋、Mg2＋和Cu2＋,对茵体的生长都有一定的抑制作用,但却都能提高胞外多糖的产量,促进作用依次为Zn2＋〉Fe2＋〉Ca2＋〉Cu2＋）Mg2＋,最大比对照分别提高了280．3％、160．5％、83．6％、52．6％和19．2％。     

滇西北松口蘑菌塘的生态因子调查

以滇西北丽江市拉市乡松口蘑(Tricholoma matsutake)产地为例,进行了松口蘑菌塘生态因子的调查。结果发现:(1)松口蘑菌塘多集群分布于狭窄的山脊及西南坡,坡面坡度在30~60°之间,上层云南松荫蔽度0.4~0.6,下层高山栎、黄背栎等灌木丛荫蔽度达0.7~0.9,落叶层及腐质层1~6 cm;(2)出菇期间菌塘地表附近空气的平均温度14.1℃,平均相对湿度78.7%;(3)出菇期间菌塘的地下温度在15.0~20.5℃之间,西南坡的菌塘温度相对较高;(4)菌塘土壤的含水量比非菌塘土壤的含水量低,出菇期间平均低16.7%;(5)菌塘土pH约为5.5,比非菌塘土低7.9%;(6)菌塘土除全钾的含量比非菌塘土高之外,其余营养成分均比非菌塘的低。

Fruiting pattern of Tricholoma matsutake in Southern Finland

Commercial harvesting of matsutake in Finland has driven the need to understand how fruiting is affected by climate and habitat. A productive site in Finland was studied in this respect. Productivity, duration, and early onset of fruiting were examined in relation to mean air temperature, soil temperature, accumulated degree-days, and precipitation. We monitored the fruiting of matsutake and other macrofungi during 2008–2013. As a pilot study, our results showed the timing and yield of the annual fruiting of Tricholoma matsutake varies in Southern Finland and can occur from the middle of July to middle of September; although we did not find a clear and simple correlation between fruiting and rainfall, an average amount of precipitation (i.e. 90–110% of the long-term average precipitation) prior to the first fruiting was associated with high yield; we did not identify any threshold soil temperature associated with the onset of fruiting, however, we found that soil temperature might provide a means to monitor the end of the matsutake fruiting period, and late onset or higher soil temperatures prior to the first fruiting were associated with shorter fruiting periods. These results can be further utilized for developing a model to predict the yield of T. matsutake in Nordic regions.     

AAS测定巨大口蘑子实体及生长土壤微量元素

本文所述用原子吸收法测定巨大口蘑子实体及生长土壤微量元素，其结果是红河菌株和思茅菌株子实体的微量元素富集量有较大差异，生长土壤微量元素富集量与子实体中的微量元素富集量都有密切关系。该方法操作简便、分析快速，测定结果令人满意。     

松茸人工促繁技术研究

在松茸生长的林地里，以不同的腐殖质厚度、郁闭度、菌种处理为因子，开展正交实验，比较松茸子实体的数量、产量、菌塘增殖情况。结果表明每50m^2的松茸林地每年留一个开伞菌、使松茸林地的郁闭度在0．6、腐殖质厚度在3-5cm最有利于松茸的生长发育。
