Abstract: | To clarify the effects of peripheral herbal plants onGlehnia littoralis growth in coastal sand dunes, the morphology of their aboveground portions was surveyed in five communities:Carex kobomugi, Calystegia soldanella, Ischaemum anthephoroides, Oenothera biennis, andElymus mollis. Correlation coefficients (CC) were generally significant at the 1% level between community properties total aboveground
biomass (B) and height (H) of dominant species per unit area] and those ofG. littoralis leaf number (Nl), petiole angle (Anp), petiole length (Lp), petiole weight (Wp), Lp/Wp, Lp/weight of leaf blade (Wb), Wp/total
weight (Wt), specific leaf area (SLA), stem length (Ls), and Ls/weight of stem (Ws)J The exceptions were among four pairings:
B and NI, B and Wt, H and Nl, and H and Wt. Of the two community properties, biomass had the greatest association with leaf
properties while H was most closely related to those of the stems. Petiole angle increased along with leaf order, from 0°
to 42° for the C.kobomugi community, from 5° to 55° forCalystegia soldanella, from 49° to 74° forI. anthephoroides, from 54° to 80° forO. biennis, and from 75° to 85° forE. mollis. In all communities, the properties of Wp, SLA, and Wb increased up to the third or fourth leaf, but then decreased; the exception
was for Lp/Wp, which was the reverse. Leaf order of the largest one moved from first position to third as either B or H increased
in a community. |
