Genetic diversity associated with natural rubber quality in elite genotypes of the rubber tree. The objective of this study was to evaluate the genetic variability of natural rubber latex traits among 44 elite genotypes of the rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Müell. Arg.... ... Repository: BDPA Publication year: 2021
Dynamic of organic matter in the conversion of primary forest in rubber tree in the central amazon region. The removal of primry forest causes a significant reduction of the microbial biomass of C and soil fertility. With the introduction of stands of rubber tress can be a continuos recovery of the amount... ... Repository: BDPA Publication year: 2007
Infuence of rubber trees on leaf-miner damage to coffee plants in an agroforestry system. The coffee leaf-miner (CLM) (Leucoptera coffeella Guérin-Mèneville; Lepidoptera: Lyonetiidae), the main pest of coffee plants, occurs widely throughout the Neotropics where it has a significant, negat... ...

Coffee water use in agroforestry system with rubber trees. A absorção e uso da água pelas plantas são processos essencialmente energéticos que podem ser grandemente modificados pela porcentagem de cobertura do solo, tipo de plantas, área foliar e sua distribu... ...

Cyanogenesis and the onset of tapping panel dryness in rubber tree. The objective of this work was to study the influence of cyanogenesis on the onset of irreversible tapping panel dryness (TPD) and the physiological and histological aspects of secondary phloem in the... ...

Population dynamics of Leptopharsa heveae (Hemiptera: Tingidae) and Erythmelus tingitiphagus (Hymenoptera: Mymaridae) in rubber tree plants. The tingid Leptopharsa heveae, known as the lace bug, occurs in large populations in rubber tree plantations, limiting the production of latex due to losses of photosynthetic area and weakening of the... ...

Measurement and simulation of solar radiation availability in relation to the growth of coffe plants in an agroforestry system with rubber trees. Solar radiation is an important factor for plant growth, being its availability to understory crops strongly modified by trees in an Agroforestry System (AFS). Coffee trees (Coffea arabica cv. Obatã I... ... Repository: BDPA Publication year: 2007
Soil carbon fractions in rubber trees, pasture, and secondary forest areas. This study quantify the total organic carbon content, light fraction organic matter (LFOM), and soil organic matter fractions (from chemical and physical fractionations) in four different cultivation... ...

Diversity of Meloidogyne exigua (Tylenchida; Meloidogynidae) populations from coffee and rubber tree. Isozymes (esterase and malate dehydrogenase), SCAR and RAPD-PCR were studied in 15 populations of three races of Meloidogyne exigua collected in coffee-producing areas in Brazil, Bolivia and Costa Ric... ...
