SUMMARY:

The biospeckle technique has been used as a tool for analyzing the biological materials activity, monitoring moisture, activity level and presence of parasites, through of the material illumination by a low power laser source. As it is a non-destructive technique, the biospeckle is an advantageous tool in fast procedures and with great precision, especially in the biological systems analysis. Thus, the objective of this research was to identify and characterize the leaf morphophysiology of Tabebuia aurea (Mart.) species submitted to water restrictions and the application of a particle film using biospeckle technique. The experiment was conducted at the Plant Physiology (LABFIVE) and Biospeckle (LEB) Laboratories and in a greenhouse at the Federal University of Alagoas, Campus Arapiraca. The experimental design was in randomized blocks (DBC) with 4 treatments [irrigated + presence of film; irrigated + absence of film; non-irrigated + film presence; non-irrigated + no film] with 4 repetitions for each treatment. Tabebuia aurea (Mart.) seeds collected from matrix trees located on the Campus Arapiraca of the Federal University of Alagoas - UFAL, were germinated in polyethylene pots with a capacity of 3L in a greenhouse (with shading of ~ 50%) until establishment of the seedlings. After the growth and seedlings establishment, the plants were transferred in the early morning hours (between 5:30 and 6:00 a.m.) to the environment outside the greenhouse under full sun, and subjected to treatments. After the treatments imposition, the evaluations were carried out for a period of 30 days. In which, the morphological and biological activity analyzes in the leaves were started at time 0, 24 hours (one day), 48 hours (two days), 72 hours (three days), seven days, 15 days and 30 days. The collected data were submitted to statistical analysis and graph plotting using the R i386 statistical software. The variables plant height index (AP), stem diameter (mm), and number of leaves in Tabebuia aurea (Mart.) plants, as well as biological activity (MDI) and homogeneity responded significantly between treatments irrigation (with and without) in the presence or not of the particulate film.
