接种外生菌根真菌对柏木幼苗生长的影响

Effects of Ectomycorrhiza Fungi on Seedling Growth of Cupressus funebris

对柏木幼苗接种外生菌根真菌土生空团菌(Cenococcum geophilum)、松乳菇(Lactarius delicious)和彩色豆马勃(Pisolithus tinctorius)进行接种与不接种处理,测定其生长指标,结果表明:与CK比较,接种3种外生菌根真菌后促进了柏木幼苗高生长和地径生长,其中松乳菇对柏木苗高生长影响最大,其次为土生空团菌和彩色豆马勃;对柏木苗地径生长以土生空团菌影响最大,其次为松乳菇和彩色豆马勃。相关性研究表明,柏木苗接种与不接种处理高生长和地径生长之间呈显著相关性,但不同的接种处理相关性不同,其中相关系数最小为不接种处理(CK),最大则为松乳菇接种处理。总体上3个菌种生长促进效应最好为土生空团菌和松乳菇。

The Cupressus funebris seedlings were inoculated by Cenococcurn geophilurn, Lactarius delicious and Pisolithus tinctorius, to investigate effects on seedling growth. The results show that three fungi can improve plant height and diameter growth of Cupressus funebris seedlings compared with CK, Lactarius delicious has the best effect on growth of plant height and Cenococcurn geophilurn has the best effect on growth of plant diameter. There is a significant correlation between inoculation and no-inoculation treatments in plant height and diameter and there is the different correlation between inoculation treatments. The promoting growth effect of Cenococcurn geophilurn is the best and Lactarius delicious is the better in three tested fungi.
