ANATOMIA FOLIAR DE ORA-PRO-NOBIS CULTIVADO SOB TELA FOTOSSELETIVA

Abstract

Ora-pro-nobis is a vine, it has long and thorny branches in the axils of the leaves of which are elliptical and fleshy. The leaves have high protein content and absence of toxicity and for this reason it becomes important for both human and animal feeding. The photo-selective nets are used as techniques for manipulating light quality, they represent a new agro-technological concept, which is intended to combine physical protection together with differential filtration of solar radiation, to favor the physiological responses that are regulated by light. The objective of this study was to evaluate the effect of light quality by the use of colored meshes in the Pereskia aculeata Miller leaf anatomy. The seedlings were planted in plastic pots and submitted to treatments in full sun and shading with a red colored net. After 120 days of cultivation, five plants were selected at random within each treatment to perform the anatomical study. The cultivation environment provides anatomical changes in P. aculeata Miller leaves. The treatments under full sun (control) and under the red net favor the increase of stomatal density.
