14. Morpho-anatomical, physiological and biochemical changes in rubber tree seeds
ABSTRACT The physical, physiological and biochemical changes during the development until the dispersal of rubber tree seeds were evaluated with the purpose of estimating the point at physiological maturity. A total of 30 plants were selected at different points in a commercial planting area and had their flowers marked during the anthesis and every 15 days

15. Clones, substrates and environments for seedlings of rubber tree rootstocks
ABSTRACT The objective of this study was to evaluate the growth of rubber clones GT1, PR255, RRIM600 grown on different substrates and environments for the production of rubber rootstocks. The experiment was conducted at the Universidade Estadual de Mato Grosso do Sul, Cassilândia University Unit, in Cassilândia-MS. The treatments were conducted in 3 envir

16. Identification and characterization of MAGO and Y14 genes in Hevea brasiliensis
Abstract Mago nashi (MAGO) and Y14 proteins are highly conserved among eukaryotes. In this study, we identified two MAGO (designated as HbMAGO1 andHbMAGO2) and two Y14 (designated as HbY14aand HbY14b) genes in the rubber tree (Hevea brasiliensis) genome annotation. Multiple amino acid sequence alignments predicted that HbMAGO and HbY14 proteins are structura

17. Performance and genetic assessment of rubber tree clones in Southern Thailand
Thailand is the world leader in the production of latex extracted from the rubber tree (Hevea brasiliensis). However, the most cultivated clone RRIM 600, is highly susceptible to diseases, and there is economic incentive to develop new rubber tree clones. Four rubber tree clones (T2, SK1, NK1 and SK3) that have high latex yield potential from plantations in

18. Effects of powdery mildew infection on chloroplast and mitochondrial functions in rubber tree
Powdery mildew (Oidium heveae Steinm.) is one of the most important leaf diseases in rubber tree (Hevea brasiliensis). However, physiological and molecular processes associated with the Hevea-powdery mildew interaction are still unclear. In this study, effects of powdery mildew infection on the mitochondrial and chloroplast functions in rubber tree were comp

19. Reappraisal of the black mildews (Meliolales) on Hevea brasiliensis
The rubber tree (Hevea brasiliensis) is host to several fungal species, including Irenopsis heveae as described by Hansford in 1961, which causes black mildew on leaves. One specimen of Irenopsis heveae from the state of Espírito Santo and two from the state of Pará were analyzed and showed some morphological differences. Some structures are similar to mor

20. Impact of the timing and duration of weed control on the establishment of a rubber tree plantation
A produção da seringueira é reduzida pelas plantas daninhas que competem por recursos ambientais; portanto, a época e duração do controle de plantas daninhas influencia a interferência das plantas daninhas. Os objetivos deste estudo foram: avaliar o crescimento de plantas de seringueira (Hevea brasiliensis), determinar o período crítico para control

21. Defense responses to Meloidogyne exigua in resistant coffee cultivar and non-host plant
The resistance of coffee plants to Meloidogyne exigua is conferred by the gene Mex-1. However, the mechanisms of resistance still need to be clarified. Therefore, the penetration, development and reproduction of two populations of M. exigua (M1, isolated from the coffee plant and M2, from rubber tree) in susceptible (Coffea arabica 'Catuai') and resistant (C

23. Modificações teciduais e mecanismos de ação da fração F1 do látex da seringueira Hevea brasiliensis na cicatrização de úlceras cutâneas em ratos diabéticos / Tissue modifications and mechanisms of action of F1-fraction of latex from Hevea brasiliensis rubber tree on wound healing in diabetic rats.
O diabetes, relacionado ao estresse celular, altera consideravelmente a cicatrização de úlceras cutâneas. O látex da seringueira Hevea brasiliensis tem se apresentado como importante indutor da cicatrização especialmente nas ulcerações comprometidas pelo diabetes no qual foi observado clinicamente estímulo do látex à total reepitelização. Foram

24. Species composition and reproductive modes of anurans from a transitional Amazonian forest, Brazil
The aim of the present study was to describe the species composition and reproductive modes of an anuran community from a transition area between the Amazonia and Cerrado biomes. Data were collected in habitats exhibiting different degrees of anthropogenic degradation. The community (35 species) identified during the present study presented a larger number o
