At a very low PPFD (20 \u00b5mol<sup>.<\/sup>m<sup>-2 .<\/sup>s<sup>-1<\/sup>), the basidiome development ceased, although some residual growth was observed for a few days. At an intermediate PPFD (50 and 90 \u00b5mol<sup>.<\/sup>m<sup>-2 .<\/sup>s<sup>-1<\/sup>), basidiome growth was less rapid than that observed at 330 \u00b5mol<sup>.<\/sup>m<sup>-2 .<\/sup>s<sup>-1<\/sup>. Significant differences in the net photosynthesis of the host plant resulted in corresponding changes in basidiome biomass. The effect of basidiome removal on the photosynthetic response of the host plant was evaluated at three stages of basidiome development (2- to 4-, 6- to 8-, and 10- to 15-mm pileus diameter). At each developmental stage, removal of the basidiome induced a very rapid decrease in both net photosynthesis and stomatal conductance of the host plant. This decrease in net photosynthesis indicates that the growth and development of the basidiome are dependent on the host plant&#8217;s current rate of net photosynthesis.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Published in Canadian Journal of Forest Research Development of the Laccaria bicolor (Maire) Orton basidiome in association with container-grown Pinus strobus L. seedlings was influenced by photosynthetic photon flux densities (PPFD).
