| diversity of endophytic fungi of single norway spruce needles and their role as pioneer decomposers. | the diversity of endophytic fungi within single symptomless norway spruce needles is described and their possible role as pioneer decomposers after needle detachment is investigated. the majority (90%) of all 182 isolates from green intact needles were identified as lophodermium piceae. up to 34 isolates were obtained from single needles. generally, all isolates within single needles had distinct randomly amplified microsatellite (rams) patterns. single trees may thus contain a higher number of ... | 2001 | 11472547 |
| decomposition and fungi of needle litter from slow- and fast-growing norway spruce (picea abies) clones. | the fungal species involved in the decomposition of needle litter and their response to intraspecific genetic variation of trees are poorly known. first, we compared the needle decomposition and fungal decomposers underneath eight different norway spruce clones in situ. this experiment revealed 60-70% loss of needle mass in two years. although spruce clones differed considerably in growth (twofold height difference) and their needles differed in chemical composition, no significant difference wa ... | 2008 | 17943340 |
| fungal diversity of norway spruce litter: effects of site conditions and premature leaf fall caused by bark beetle outbreak. | fungi play an important role in leaf litter decomposition due to their ability to break down the lignocellulose matrix, which other organisms are unable to digest. however, little is known regarding the factors affecting components of fungal diversity. here, we quantified richness of internal fungi in relation to litter nutrient and phenolic concentrations, sampling season (spring or fall), and premature leaf shedding due to low precipitation and infestation of bark beetles (mainly ips typograph ... | 2008 | 18095016 |
