Both nymphal and adult spittlebugs (Hemiptera: Cercopidae) cause serious economic damage to susceptible brachiariagrass [genus Biachiaria (Trin.) Griseb], pastures in tropical America. Both life stages are xylem feeders: nymphs feed primarily on roots and stems, whereas the adults feed mainly on ...

Apomixis—asexual reproduction through seed—provides a convenient means to faithfully propagate even heterozygous genotypes and hence exploit heterosis, in several naturally apomictic, warm-season forage grasses. Inheritance of apomixis has been shown to be monogenic dominant in at least four econ...

Anthracnose, caused by Colletotrichum gloeosporioides, is the most important and widespread disease of Stylosanthes, a diverse tropical and subtropical forage legume naturally distributed in central and South America. This paper compares the genetic and pathogenic diversity of 45 isolates, which ...

Genetic and pathogenic diversity in Colletotrichum gloeosporioides isolates from Stylosanthes guianensis

Brachiaria grasses are sown in tropical regions around the world, especially in the Neotropics, to improve livestock production. Waterlogging is a major constraint to the productivity and persistence of Brachiaria grasses during the rainy season. While some Brachiaria cultivars are moderately tol...

Aim: Utilization of biological nitrification inhibition (BNI) strategy can reduce nitrogen losses in agricultural systems. This study is aimed at characterizing BNI activity in a plant-soil system using a biparental hybrid population of Brachiaria humidicola (Bh), a forage grass with high BNI pot...

The effects of size of terminal stem cuttings (2-, 3-, or 4-leaf) and of auxin treatment on percent rooting, root number and root length of six Stylosanthes guianensis accessions were evaluated in a single, factorial experiment. Overall, 66% of cuttings rooted within ten days. Accessions differ...
