Photosynthetic Assimilation of the Guava (Psidium guajava) cv. Paluma under Different Pruning and Fruit Thinning Intensities

In guava plants, production pruning can be performed twice a year, and the return of growth is dependent on physiological responses that are altered by different cultivation environments adopted management. From this perspective, study aimed to characterize photosynthetic dynamics plants influenced fruit thinning intensities during two growing seasons in region Currais, Piauí, Brazil. The were distributed randomized block design with factorial arrangement (3 × 3 2) consisting three (short, medium, long) (0, 10, 20%) seasons. data subjected cluster analysis canonical discriminant discriminate treatment groups based variables. Through for evaluated treatments, it was possible split into five clustered first season second season. highest assimilation values observed especially received short 0% thinning, medium 10% 20% long thinning. graphic representation analysis, variables explained 93.40% total variance contained nine original means ambient PAR, transpiration, leaf temperature, internal carbon, temperature 0%, 10%, favors higher accumulation plants.
