Jones' ANOVA (Table 8) revealed that both additive (a) and dominance (b) components is significant for the stomatal density at both surfaces and gsat the adaxial
surface across all irrigation regimes.
Abbreviations: proportion Of the adaxial
epidermis (ADE%); proportion of abaxial epidermis (ABE%); proportion of chlorophyll parenchyma (PAR%); proportion of the sum of total phloem in the leaf (PHT%); proportion of the phloem in one vascular bundle (PHVB%); proportion of the bundle sheath in the vascular bundle (BS%); proportion of the vascular bundles in the leaf (VB%); proportion of the sum of total xylem in the leaf (XLT%); proportion of the phloem in one vascular bundle (XLVB%); proportion of the sum of total fibers in the leaf (FBT%), proportion of the fibers in one vascular bundle (FBFV%).
Es interesante la presencia de variegacion rosada a rojiza sobre las nervaduras laterales principales en la cara adaxial
del limbo de las hojas de esta nueva especie, caracteristica rara observada por ejemplo tambien en Passiflora trifasciata Lemaire, la brasilena P.
Based on the criteria proposed by Singh (1981), it was verified that the most important characteristics for discrimination of the genotypes were: Acylsugar content (16.75%) and presence of leaf miner larvae (14.75%), and the characters of least contribution were the amount of adaxial
trichomes (9.88%) and abaxial amount of trichomes (9.25%) (Table 2).
The distribution of these structures is diffuse, which are located on the adaxial
and abaxial face of the leaf.
The epidermal cells may be tall or voluminous on the adaxial
The trichome types located on the adaxial
and abaxial sides of leaves are same except T.
Among them, the genes of the KAN and REV transcription factors, responsible for the abaxial and adaxial
cell identity in lateral organs, respectively, and their common targets (ARF, SAUR, Aux/IAA, PID, PIN, NPY, GH3, etc.) involved in auxin biology  were identified.
The characteristics of the adaxial
(upper) and abaxial (lower) epidermis for the polluted and non-polluted populations of Senna occidentalis are summarized in Tables 1-2 and illustrated in Fig.
leucocephala tree vertical canopy stratification (upper, middle, basal parts, and trunk), horizontal stratification (branch orientation related to sun exposure: north, south, east, and west faces) and leaf surfaces (adaxial
and abaxial parts).
