Apesar das limitações nutricionais e elevada acidez dos solos, a flora do cerrado é a mais rica entre as savanas. Muitas espécies lenhosas do cerrado possuem folhas escleromórficas e o nível de escleromorfismo foliar parece depender da disponibilidade de água e nutrientes no solo. Visando um melhor entendimento sobre a estrutura e funcionalidade da vegetação do cerrado, foram comparadas duas comunidades de cerr...
Citrus variegated chlorosis (CVC) is a disease caused by Xylella fastidiosa. Using different concentrations of plant regulators, such as auxins (indole-3-butyric acid) and gibberellic acid biosynthesis-inhibitor (paclobutrazol), physiological rooting capacity of healthy and CVC-affected stem cuttings were evaluated in order to investigate the importance of plant hormone imbalance and xylem occlusion in plants w...
The experiment was carried out in a commercial orchard of ‘Ponkan’ mandarin (Citrus reticulata Blanco), grafted on ‘Cleopatra’ mandarin (Citrus reshni Hort. ex Tan.), in Pratânia, state of São Paulo, Brazil. The utilized experimental design was composed of randomized blocks of four replications. The treatments consisted of: 0 (control), 5, 10, 15 and 20 mg L1 of Gibberellic acid (GA3).
