The elephant grass (Cenchrus purpureus (Schumach.) Morrone) is one of the species with great prominence for energy production because of its favorable traits, such as high yield and short cycle, combined with several biomass quality characteristics. Therefore, this study intended to evaluate the morpho-agronomic traits of eight elephant grass genotypes under different cutting ages. A randomized block design with three replicates was applied to the experiment, and plots were composed of a 12 m long line divided into six subplots for each of the bimonthly cuts. Eight genotypes were evaluated in the plots, and the cutting ages (2, 4, 6, 8, 10, and 12-mo) were analyzed in the subplots. The following traits were assessed: DM yield, (DMY) percentage of DM, and average plant height (HEI). All genetic-statistical analyses were conducted using the Genes Program. The evaluated genotypes showed nonsignificant differences, indicating that, for the evaluated traits, these genotypes are genetically similar. Most genotypes presented linear effect of 2nd degree in the two assessment cuts, pointing they did not reach their maximum capacity of DMY in the time interval of the evaluated cuts. The maximum %DM achieved for the most genotypes occurred at about 9-mo age, while genotypes Vruckwona and BAG-86 at about 10-mo age. The maximum points for HEI trait were between 8 and 10-mo age. Increasing the cutting interval leads to increases in DM yield, with the 10-mo cutting age being the most efficient, resulting in higher yields.

The objective of this work was to obtain protoplasts from napier grass and pearl millet triploid hybrids as a basis for future studies on chromosomal duplication. Explants were taken from mesophyll of in vitro- and in vivo-cultured plants or from calli of two triploid hybrids (H1 and H2), which were treated with enzymatic solutions containing different concentrations of cellulase R-10 (0.5, 1.0, 1.5 and 2.0%) with an additional 0.2% macerozyme and 0.1% driselase or 1.0% pectolyase Y-23 and 0.5% hemicellulase. Enzymatic digestion was monitored once every hour for five hours. Protoplasts were obtained from in vitro and in vivo leaflets of both triploid hybrids, and in vitro leaflets were the best explant sources. The quantity of produced protoplasts varied according to the hybrid, the enzymatic solution and the treatment time. |
