| The sucará also known as Gleditschia amorphoides is a important for the regeneration of riverine areas. Due to the presence of numbness imposed by the tegument, occurs late in seed germination, and obtaining the results, often does not correspond with the real force of the same. The tetrazolium method was used to assess the viabilidade of seed, especially because it is accurate, fast, low cost and easy to perform. This study aims to evaluate the seed vigor sucará from different sources through the tetrazolium test and seedling development. We used three seed origins, looking through the germination test, germination percentage, germination speed index, length of shoot and root mass of seedling. Parallel testing was held water content, weight of thousand... |

| The soybean, one of the most important cultures in Brazilian agriculture, is a profitable culture due to the use of brand new technologies in the development of new cultivars, which contain more and more biotechnologies that turn the crop management easier. Among these technologies, there is the INTACTA RR2 PRO®, which was recently released. However, there are few studies to show the most yielding cultivars indicated to Marechal Cândido Rondon. So, the aim of this study was to evaluate some cultivars indicated to this region and then recommend them to the farmers. A couple of agronomic characteristics were evaluated, focusing in the yield and cycle. The randomized block design was used, with four replications. The obtained data was submitted to variance... |

| As β-1,3 glucanases de plantas são enzimas abundantes e comumente encontradas no reino vegetal, estando envolvidas em vários processos fisiológicos, especialmente na defesa vegetal. A defesa vegetal é baseada em uma série de barreiras pré e pós-formadas, ambas subdivididas em estruturais e bioquímicas. As barreiras estruturais atuam contendo o patógeno fisicamente, enquanto a ação bioquímica opera através da produção de substâncias tóxicas e antimicrobianas, como a produção de enzimas hidrolíticas (proteínas relacionadas à patogênese ou PR proteínas). O objetivo desta revisão é abordar o papel das β-1,3 glucanases em plantas, sobretudo nos mecanismos de defesa vegetal ativados pela indução de resistência, a qual tem por objetivo estimular os vegetais a... |
