ABSTRACT The center of diversity for Passiflora subg. Astrophea is in low altitude areas of northern South America. The majority of species of this group are difficult to find in nature. Seed morphology was described in detail for 25 species of Passiflora subgenus Astrophea, a subgenus that until now did not exist. For morphological analysis, 20 seeds per species were measured for length, width and thickness, and the arithmetic means calculated. The seeds varied in length, width and thickness. Eight types of ornamentation were found. The margins varied among crestate, dentate, parted, entire and parted-crestate. The seed apex can be distinguished by the shape and position of the apical appendage. Seed shape varied among obovate, lanceolate, cordiform, and... |

The objective of this work was to characterize and cluster isolates of Pestalotiopsis species and to identify those that are pathogenic to pecan, based on morphological and molecular characters. Pestalotiopsis spp. isolates were identified by sequencing the internal transcribed spacer (ITS) and β?tubulin regions. Identification methods were compared to indicate the key morphological characters for species characterization. Thirteen isolates were used for the pathogenicity tests. Morphological characterization was performed using the following variables: mycelial growth rate, sporulation, colony pigmentation, and conidial length and width. Ten pathogenic isolates were identified, three as -tubulin regions. Identification methods were compared to indicate... |

We describe a new species of Cyrtoneuropsis Malloch, 1925 (Diptera, Muscidae) from Brazil. The new species is included in a previously published key to species. Additionally, we review a previously published matrix to Cyrtoneurina Giglio-Tos, 1893 and Cyrtoneuropsis. A total of 52 character states were modified and the new species was added to it. The modified matrix was analyzed under equal and implied weights. In all topologies, Cyrtoneuropsis spiloptera (Wiedemann, 1830) came up as the sister group of the new species. The monophyly of Cyrtoneurina and Cyrtoneuropsis were recovered, but the relationships among their species, in our data, differ from those obtained in the past. |

Ninety-three samples of high land rice, “Bue Po Lo” variety from Mae Hong Son province and one sample of “Eto” variety from Chiang Rai province were evaluated for genetic diversity at Maejo University during June to December of 2012. Treatments were arranged in a Randomized Complete Block design with 2 replications. Cluster analysis of quality characters using NTSYS software was performed to construct dendrogram. The results found that sheath color, internode color, awn character, stem pattern, flag leaf pattern, panicle base pattern, stem vigor, secondary branch pattern, panicle pattern, panicle exertion and threshing were significantly different. While, leaf pubescence, ligule pattern and stigma color were not significantly different. Cluster analyses of... |
