"leaf characteristics" is correct and commonly used in written English.
It refers to the specific traits or features that describe or distinguish one leaf from another. Example: The botanist carefully observed the leaf characteristics of the plant, noting its shape, size, texture, and venation pattern.
Global changes induced species-specific changes in plant leaf characteristics, leading gastropods to alter the relative amounts of different plant types consumed.
Boso Alonso S, Alonso-Villaverde Iglesias V, Santiago Blanco JL et al. Macro-and microscopic leaf characteristics of six grapevine genotypes (Vitis spp). with different susceptibilities to grapevine downy mildew.
Three similar north-south orientated streets, with three different tree species possessing different canopy and leaf characteristics were studied in summer 2014.
Leaf characteristics (leaf angle, leaf length, and leaf number), growth form (tiller height and tiller clusters), bud proliferation, and plant fitness differed significantly in situ along the gradient.
Anatomical and developmental constraints likely contribute to the stability in leaf characteristics - and ecophysiology - seen through time in different lineages and contribute to the uniqueness of angiosperms in achieving the highest vein densities, stomatal densities, and physiological rates.
Growing from 15 to 25 metres tall, the tree resembles the yellow woods in leaf characteristics and growth habit but differs in flower structure and the presence of the seed covering.
A two-way ANOVA model with shading and provenance as the main fixed factors plus a shading × provenance interaction term, followed by Tukey's multiple-range test, was performed for each leaf characteristic, flavonoid concentration, plant growth, and flavonoid accumulation per plant.
One leaf characteristic that did differ between the treatments was stomatal density.
There are also plants with enzymatic and leaf anatomical characteristics intermediate between C3 and C4 plants, called C3-C4 intermediate species.
These studies have been directed at investigations into the mechanisms by which fungi use leaf surface characteristics to sense the right time and place to infect their host.
Consequently, yield improvement in maize was probably a result of increased plant density tolerance through dependence on changes in leaf orientation characteristics.
