菌根真菌菌种的更替与其可持续性的研究   总被引:2,自引:0,他引:2       下载免费PDF全文
巨尾桉菌根化组培苗试验林中所接种的彩色豆马勃,已持续生存达10a之久;而接种的西澳粘滑菇、漆蜡蘑仅生存2~6a,之后则被其它菌根菌种所更替。自然条件下未经接种的的蓝桉人工林,造林后2~4a的林中以硬皮马勃、漆蜡蘑等菌根真菌为主;之后则先后由鸡油菌和牛肝菌所取代。松茸菌在适合的自然条件下可在林中生存达数十年之久,其持续性十分明显;人工接种松茸菌的云南松幼苗上,经6a的连续观察,菌丝体仍然生长旺盛。菌根真菌的菌种更替现象及可持续性与菌种本身的生长特性有关。若菌种能适应其环境条件,则生长可持续下去;反之则可能被其它菌种所更替,因此,菌根技术的推广应用,应坚持“适地适菌”和“适树适菌”的原则,方可取得持久的接种效果。  相似文献

The commercial harvest of American matsutake (Tricholoma magnivelare) is a multi-million dollar industry in the Pacific Northwest region of North America. How to best manage for sustainable mushroom production is uncertain and concerns remain about the cumulative effects of picking in the same areas year-after-year and whether raking of surface litter and mineral soil layers to find mushrooms will reduce subsequent fruiting. Here, we evaluate the effects of several mushroom harvest techniques on American matsutake production.This study was established in the Oregon Cascades in 1994 with the selection of 18 shiros of similar mushroom production. Six mushroom harvest treatments were implemented in 1995: (1) control, (2) best management practice (BMP), (3) shallow rake, litter replaced, (4) shallow rake, no replacement, (5) deep rake, litter replaced, (6) deep rake, no replacement. These treatments were pooled into three litter disturbance groups for analysis: (a) no raking of the litter, (b) litter raked with replacement, and (c) litter raked without replacement.Matsutake production on additional shiros was monitored to further compare the control and BMP treatments. Our results demonstrate that careful picking (BMP) was not detrimental to mushroom production during the initial 10 years of mushroom harvest activity. One-time treatments in which the forest floor litter layers were removed and not replaced were strongly detrimental to matsutake production and the effects have persisted for 9 years. Matsutake production was reduced to an intermediate degree by the raking with litter replacement treatments. Damage to shiros caused by repeated raking was not tested, however we expect that the effects of repeated raking would be more severe than those reported here. Negative treatment effects were particularly noticeable in years with abundant fruiting. When environmental conditions are poor for fruiting all shiros experience low production, thereby obscuring treatment effects.Within-year and year-to-year variation in fruiting is a major challenge to studies of matsutake ecology, particularly with regard to documenting treatment effects. Further studies spanning years or even decades will likely be needed to quantify production, effects of management activities, and investigate the biology of Tricholoma magnivelare.Because this study was limited to one habitat type, extension of the results to substantially different habitats types must be made with caution. However, we speculate that since the underlying biology of matsutake fruiting is similar across a wide range of habitats, careful picking should generally not hinder subsequent fruiting when other substantial disturbance to the shiro is absent.  相似文献

The assemblages of fruitbodies produced by sheathing mycorrhizal fungi associated with clones of Betula spp. were affected by ‘host’ genotype and the origin of propagating soil during the first 6 years after transplanting into a groundwater gley with mull humus.Significantly more fruitbodies were produced when rooted cuttings were propagated in soil A than in soil B, on average 19.5 compared with 4.5 per tree. The larger numbers in soil A were associated with a preponderance of fruitbodies of Laccaria tortilis; Hebeloma spp. being relatively more abundant in soil B.Appreciably more fruitbodies were associated with clone 12.5D of B. pendula than with clone 9.3D of B. pubescens, 19.9 compared with 4.6, the difference being largely attributable to the ‘substitution’ of the prolific L. tortilis by the sparse Inocybe petiginosa.Whereas soil type had a significant effect on numbers of fruitbodies associated with the three more productive clones, it had no effect on numbers of fruitbodies associated with clone 9.3D.  相似文献

Falling needles collected from under individual 70-year-old Norway spruce (Picea abies) trees for about four years were checked for fungal fruitbodies. The most common fungi were Lophodermium piceae and Rhizosphaera kalkhoffii. Maximum frequencies of fruitbodies occurred in late autumn for L. piceae (ca. 80% of the needles), in summer for R. kalkhoffii (ca. 60%) and in winter for the third most common fungus, Tiarosporella parca (ca. 10%). The frequencies of needles with fruiting fungi varied greatly within and between years. This is the first report of T. parca from Sweden.  相似文献

We investigated the seasonal appearance and longevity of fruitbodies of Agaricales in a mixed forest dominated by Pinus densiflora (Sieb et. Zucc.) for about 3 years. A total of 3563 fruitbodies in 27 genera from 13 families appeared; Collybia, Marasmius, Mycena, Rhodophyllus, and Lactarius were dominant. The seasonal trend of appearance of fruitbodies differed among genera. There were no significant relationships between any factors of temperature and the number of fruitbodies in any of the dominant genera or Amanita. The number of fruitbodies of Mycena and Lactarius increased with the indices of precipitation. The longevity of fruitbodies ranged from 2.6 days in Mycena to 71.9 days in Lactarius. The longevity in Collybia and Mycena, which appeared in early summer, increased as the highest daily temperature became higher. On the other hand, that of Marasmius, Amanita, Rhodophyllus, and Lactarius, which appeared in autumn, increased as the lowest daily temperature became lower. The longevity of fruitbodies in every genus surveyed except Amanita decreased as the frequency of precipitation increased. It is possible that the rate of deterioration is higher in June–July than in September–December, and the longevity of fruitbodies might vary with the temperature. On the other hand, precipitation would facilitate the appearance of fruitbodies and shorten their longevity in Mycena and Lactarius.  相似文献

When stydying the growth of different provenances of Betula pendula and B. pubescens it was noted that fruitbody production by many sheathing (ecto-)mycorrhizal fungi followed distinctive patterns in time and place.When saplings of B. pendula and B. pubescens, from seed collected from ranges of locations in western Europe, were grown on a brown earth at latitude 55° 52′ N, autumnal yellowing and defoliation occurred sooner on saplings originating from northern locations (Scandinavia, 60°–66°N) than on those from the south (United Kingdom and Germany, 50°–55°N); the latter group of trees, particularly of B. pubescens, tended to be taller than the former.In the first 6 years after planting Betula spp., more than 90% of the fruitbodies (toadstools, earth-fans of Thelephora terrestris and elf-cups of Peziza badia), usually appearing in the autumn, were of fungi known, or suspected, to form sheathing mycorrhizas with Betula spp. Mean numbers of fruitbodies increased from 0.4 to 28 and 170 per tree in the 2nd, 4th and 6th years respectively after planting. Numbers of fungal species producing fruitbodies progressively increased from one, Hebeloma crustulvniforme, in the 2nd year to 14 (B. pubescens) and 18 (B. pendula) in the 6th year when Hebeloma spp. accounted for 79% of fruitbodies; Laccaria ‘laccata’, 15%; Inocybe lanuginella, 5% and Lactarius pubescens, 1%. Of the 6th year Hebeloma total, H. crustuliniforme, H. fragilipes, H. mesophaeum and H. sacchariolens accounted for 32, 33, 13 and 11% repectively.Mean distances between fruitbodies and the stems of trees widened at c. 0.16 m year?1 for Hebeloma crustuliniforme; for Laccaria ‘laccata’ they increased by 0.27 to 0.87 m year?1 between the 4th and 5th years after planting but remained virtually unchanged in the 6th year. Distributions differed within and between concentric 10 cm annuli. In the 6th year appreciably more Hebeloma fruitbodies, except those of H. sacchariolens, were found in intermediate annuli than in annuli nearest and furthest from trees. In contrast those of Laccaria ‘laccata’ and Inocybe lanuginella developed at densities of 1500 m?2 and 500 m?2 in most annuli.Fruitbodies of Laccaria ‘laccata’ were significantly clustered in sectors of the differing annuli possibly reflecting associations with radially growing secondarily thickened roots, whereas those of I. lanuginella occurred at random.From 2 to 6 years after planting the mean annual production of toadstools and elf-cups averaged 55 and 0.1 per tree originating from latitude 50° N and 66° N respectively. Earth fans of Thelephora terrestris were likewise less commonly associated with trees of northern origin.B. pubescens, unlike many provenances of B. pendula, seemed to resist invasion by the leaf rust Melampsoridium betulinum. The northern provenances of B. pendula were significantly more seriously infected than southern provenances.  相似文献
