The experiment was carried out to evaluate seven accessions of limpograss Hermathria altissima (PI 364888, NO 158, PI 364863, IPEACO 336, UF 553, UF 347238, and IPEACO 337) as compared to coast-cross grass (Cynodon dactylon), to determine which grasses were best adapted ecologically to conditions at Pindamonhangaba. The experimental design was a randomized block with four replications. Five annual harvests were taken during the three-year experimental period, two in the dry season and three in the rainy season. The higher annual DM yields (kgDM/ ha) were obtained with accessions UF 553 (19996), NO 158 (18745), and PI 347238 (18267). Accessions UF 553 and IPEACO 336 had the most uniform production throughout the year with 37.4 and 33.2% during the dry season, respectively. Coast-cross had the highest percentage of crude protein (10.30%), while limpograss values varied around 7%. It was concluded that accession UF553 was the most promising grass for the Pindamonhangaba region.

The rambutan (Nephelium lappaceum) is an exotic fruit with great market potential in Brazil. However, there are few available informations about plants with potential for cultivation, because great morphologic variation is observed among plants and for consequence, little uniformity in the orchards and in the fruits. This research had for objective to evaluate the genetic diversity of a collection of rambutan plants obtained by seeds through morfo-chemical analyses of plants and fruits and by fAFLP molecular markers, to indication of promising materials to be used in new plantings of the culture in the São Paulo State. Was verified that both markers, morphologic and molecular, were efficient in the distinction of varieties, showing the presence of genetic variability among the plants of this study. Was also verified that the materials A51 and B03 presented a larger group of desirable characteristics for new cultivations of the fruitful.
