13. Plant physiology as affected by humified organic matter
Since the beginning of Human civilization, the soil organic matter has been used as plant growth promoter and/or regulator. Indeed, early in plant science history, even before the auxin concept has been established, the term "auximones" was coined to describe plant growth promoting humic acids derived from peat. Despite of this, until the end of the 20th cen

14. ÉPOCAS DE APLICAÇÃO DE REGULADOR DE CRESCIMENTO E DE SOMBREAMENTO ARTIFICIAL AFETANDO CULTIVARES DE TRIGO
The use of the growth regulator trinexapac-ethyl aims to reduce height of wheat plants avoiding lodging and losses caused by it. In addition, causes changes leaf architecture the plant have a better utilization of solar radiation. With the aim to evaluate the effects of application times of the growth regulator trinexapac-ethyl with or without artificial sha

15. Aspectos morfofisiológicos na clonagem de Eucalyptus benthamii / Morphophysiological aspects in the cloning of Eucalyptus benthamii
Dentre as poucas espécies de Eucalyptus que apresentam aptidão ao cultivo em regiões de baixas temperaturas e a geadas frequentes, destacam-se genótipos de Eucalyptus benthamii que representam opções para futuros plantios florestais em diferentes regiões brasileiras. Porém, existem poucas informações quanto a obtenção de mudas clonais, e se focar

17. PropagaÃÃo vegetativa de miniestacas de Cordia trichotoma em funÃÃo de auxinas e Ãpocas de coleta / Vegetative propagation of Cordia trichotoma cuttings according to auxin and harvest time
It was developed a study on vegetative propagation on the rooting of Cordia trichotoma semi-woody in Summer and Fall of 2011. Therefore this study aimed to evaluate the effects of different concentrations of IBA (indolbutiric acetic) and NAA (naphthalene acetic) acids on the rooting and establishment of Cordia trichotoma semi-woody cuttings gathered from the

18. Efficient Regeneration of Eucalyptus urophylla x Eucalyptus grandis from Stem Segment
The aim of the present study was to establish an efficient regeneration system for the hybrid E. urophylla x E. grandis by means of organogenesis. Stem segments from seedlings were used as explants and cultured in a modified Murashige and Skoog medium (MS), supplemented with 13.2 µM N-phenyl-N'-[6-(2-chlorobenzothiazol)-yl] urea (PBU) and 0.285 µM indole-3

19. Expression of phenazine biosynthetic genes during the arbuscular mycorrhizal symbiosis of Glomus intraradices
To explore the molecular mechanisms that prevail during the establishment of the arbuscular mycorrhiza symbiosis involving the genus Glomus, we transcriptionally analysed spores of Glomus intraradices BE3 during early hyphal growth. Among 458 transcripts initially identified as being expressed at presymbiotic stages, 20% of sequences had homology to previous

20. Degradação do paclobutrazol em solos tropicais.
O objetivo deste trabalho foi avaliar a degradabilidade do regulador de crescimento vegetal paclobutrazol em solo. Os solos foram coletados em regiões representativas de plantios comerciais de manga para exportação, em Petrolina, PE e em Lins, SP. Culturas bacterianas mistas, isoladas destas amostras de solo foram avaliadas quanto à sua capacidade degrad
