摘要

块菌块菌在山核桃果园（Carya illinensis Wangenh）中的发生。对巴西南部的山核桃农民来说，这是一个潜在的新的收入选择。然而，关于接种这种松露物种的山核桃幼苗的营养和形态参数知之甚少。因此，我们的目的是量化佛罗里达霉与山核桃幼苗之间的外生菌根关系，并评估这种共生关系是否促进了温室条件下山核桃的生长。以巴顿山核桃苗木为材料，接种floridanum菌，在温室中培养300 d后，对其菌根率、营养和形态生长参数进行评价。结果表明，在接种10个月后，山核桃幼苗中的floridanum定殖水平较高（78.7% - 99.5%）。建议进一步研究以评估这种外生菌根结合的长期影响，特别是在延长栽培期和营养胁迫条件下。

Efficient colonization of pecan (Carya illinoinensis) seedlings by Tuber floridanum

The occurrence of the truffle Tuber floridanum in pecan orchards (Carya illinoinensis Wangenh. K. Koch) in southern Brazil represents a potential new income alternative for pecan farmers. However, little is known regarding the nutritional and morphological parameters of pecan seedlings inoculated with this truffle species. Therefore, we aimed to quantify the ectomycorrhizal association between T. floridanum and pecan seedlings, and to evaluate whether this symbiosis promotes the growth under greenhouse conditions. Pecan seedlings, cultivar Barton, were inoculated with T. floridanum, and after 300 days in the greenhouse, the percentage of mycorrhization, nutritional and morphological growth parameters were evaluated. Our results indicate high levels of T. floridanum colonization in pecan seedlings (78.7 %–99.5 %) after ten months of inoculation. Further studies are recommended to evaluate the long-term effect of this ectomycorrhizal association, particularly under extended cultivation periods and conditions of nutritional stress.

期刊介绍： Rhizosphere aims to advance the frontier of our understanding of plant-soil interactions. Rhizosphere is a multidisciplinary journal that publishes research on the interactions between plant roots, soil organisms, nutrients, and water. Except carbon fixation by photosynthesis, plants obtain all other elements primarily from soil through roots. We are beginning to understand how communications at the rhizosphere, with soil organisms and other plant species, affect root exudates and nutrient uptake. This rapidly evolving subject utilizes molecular biology and genomic tools, food web or community structure manipulations, high performance liquid chromatography, isotopic analysis, diverse spectroscopic analytics, tomography and other microscopy, complex statistical and modeling tools.
