Morphoanatomical leaf “D” evaluation of pineapple (Ananas comosus (L.) Merr. var. comosus) in response of two cropping systems in Corrientes, Argentina
A feasible possibility to cultivate tropical species in the subtropics is compensate the limitations of the low temperatures using plastic covers that modify the environment and the consequent crop response. The aim of this research was to evaluate in morphoanatomical terms, the "D" leaves of pineapple plants growing under different cropping conditions, linking some differentiations in their morphological, anatomical and ecophysiological characteristics in relation to the year seasons. Leaf area, fresh and dry weight, sheet thickness, water holding capacity, number of spines, chlorophyll content were measured and histological sections for morphoanatomical observations were carried out. In the present research, it was found that the environmental conditions under coverage, increased leaf area, dry weight and fresh weight of "D" leaves pineapple during and after the cold seasons, respect to those cropped under field conditions. Pineapple Leaves growing under greenhouse conditions, increased stomatal frequency, performed more fiber beans but thinner aquifers and chlorenchyma than those grown in field conditions, indicating phenotypic plasticity.
