MORPHOMETRICAL OBSERVATIONS ON ACER PLATANOIDES L. AND ACER PLATANOIDES VAR. SCHWEDLERI K. KOCH LEAVES


RODICA BERCU

Issue:

SCSB, Volume XVI

Section:

Volume XVI - Vegetal Biology

Abstract:

The large polymorphism of the leaves, determined us to introduce the morphometrical method and to analyze them not only by morphological but also by the morphometrical criterions, a less tackled subject in the morphological studies.

(Lp) comparatively with A. platanoides var. schwedleri; a grater values has the lobes incision deepness (Ls) of A. platanoides leaves.The percentage report indicates that the apex leaves (A/I-I’) of A. platanoides is more acute (delicate) than those of A. platanoides var. schwedleri. The angular measurements of A. platanoides var. schwedleri of the blades, exhibit that the emergent angle of the primary lateral veins (ω) are larger than those of A. platanoides. Few A. platanoides var. schwedleri leaves possesses emergent angle of the tertiary veins (γ) of insignificance value. A. platanoides var. schwedleri possesses a great number of secondary pairs of veins (Np), comparatively with A. platanoides blades.A. platanoides blades have a large surface (S) than those of A. platanoides var. schwedleri (Table 3). This method may be useful for plants varieties and forms taxonomic identification which is nor so easy thing, based on exact leaf mophometrical parameters, calculated on a great number of leaves.
