Bamboo plantation has gained great attention in Brazil due to its useful production provided to the society and the ecological,
economic, social and cultural functions of these plantations. For the establishment of high productivity plantations, evaluation of
germplasm and selection of superior genotypes is necessary. This work aimed at early evaluation of the genetic parameters of
potential bamboo species for planting in Brasília/DF. For this purpose, a clonal test consisting of seven species was established:
Bambusa oldhamii, Bambusa vulgaris, Bambusa vulgaris var. vittata, Dendrocalamus asper, Dendrocalamus latiflorus, Guadua
angustifolia and Guadua chacoensis. The experiment was planted in a completely randomized block design, with three replications
and fifteen plants per plot. At 360 days after planting, all individuals were evaluated for their characteristics: height of aerial part,
number of sprouts, clump base area, clump coverage area and density of stalks per clump. The statistical analyses were carried out
through the procedure of mixed models: Maximum Residual Likelihood/Better Non-Victimised Linear Prediction. There were
significant species effects on the characteristics of the aerial part height and number of shoots, as well as high estimates of selective
accuracies. Genetic parameters and genotypic values demonstrate genetic variability between species and the possibility of future
gains from selection. New evaluations will be carried out annually to aim a greater knowledge of the behavior of germplasms at
different ages. At the age of five (commercial court), the best genotypes will be selected for the experimental environmental
conditions. MenosBamboo plantation has gained great attention in Brazil due to its useful production provided to the society and the ecological,

Blast, caused by the fungus Pyricularia oryzae, is an important disease affecting rice and wheat yield worldwide. This study investigated the cytological aspects of incompatible (non-host resistance) and compatible (host resistance) rice- (R_Po) and wheat- (W_Po) Pyricularia oryzae isolate interactions. Inoculations of rice and wheat with the R_Po and W_Po isolates of P. oryzae, respectively, were expected to be compatible interactions (host resistance), whereas inoculations of rice and wheat with the W_Po and R_Po isolates of P. oryzae, respectively, were considered to be incompatible interactions (non-host resistance). For the compatible interactions (rice-R_Po and wheat-W_Po), fungal hyphae penetrated and colonized the epidermal cells and also invaded many neighboring cells. By contrast, in the case of the incompatible interactions (rice-W_Po and wheat-R_Po), fungal hyphae were not able to penetrate nor colonize the epidermal cells, but when penetration did occur, the hyphae were restricted to the first-invaded epidermal cell. The frequency of appressorial sites exhibiting infection hyphae within the epidermal cell underlying an appressorium was greater in the case of the compatible interactions. By contrast, unsuccessful penetrations with cytoplasmic granulation occurred with high frequency in the incompatible wheat-R_Po and rice-W_Po interactions and the number of necrotic epidermal cells underlying the appressorium was low for the rice-W_Po interaction as well as for the wheat- R_Po interaction, where no symptoms of necrosis were exhibited. However, the opposite was observed for the compatible interactions. The present study presents cytological features associated with incompatible and compatible rice- and wheat-P. oryzae interactions that may be useful to studies involving variability, coevolution, diagnosis, and regulation of quarantine or even in a rice or wheat breeding program whose aim is to transfer genes involved in non-host resistance to host resistance due to similarities in downstream mechanisms.
