“…This species has also been assessed in studies on bioenergy production, since it emerged as alternative source for biofuel production (Mohammed et al, 2015;Samson, et al, 2005;Rocha, et al, 2017) due to its high cellulose content level, fast growth, and biomass production (Campos et al, 2019), and carbohydrate content (Azeke, Eze, Ubong, & Kuroshi, 2019). Taiwan and Cameroon cultivars' total calorific value ranged from 3.905 -4.047 Kg -1 and 4.033 -4.042 Kg -1 , respectively, and these were the best results among all assessed cultivars (Marafon et al, 2020). It is essential observing that these values are similar to those recorded for sugarcane.…”

Elephant grass is a tropical forage crop highly used in dairy cattle production, in Brazil. It has been getting special attention, because of its bioenergy potential, medicinal properties, and bioremediation profile. The aim of the present study is to investigate the effects of thermotherapy based on clonal cleaning methods and meristem culture on the mineral content of elephant grass (Cenchrus purpureus (Schumach.) Morrone). Cultivars “Mineiro”, “Taiwan A-147” and “Pioneiro” were subjected to the following methods: thermotherapy (T) combined to meristem culture (MC), meristem culture and mature stems (control). The experiment assessed the mineral contents of phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S) at three cuttings, which were performed every 60 days, for 180 days. There was lack of effects from these methods on the mineral content of approximately 66% of the carried out assessments, standing out unanimity for all cultivars, methods, and most of the cuts. T+MC was the only method showing positive effect on P and Ca content, in all cuts, in the cultivars Taiwan A-147 and Pioneiro, respectively. There was clear negative effect of cleaning methods on P and Ca content, in all cuts, for cultivar Mineiro, and on Mg, for cultivar Taiwan A-147. These results, along with the positive effects observed in vegetative and nutritional parameters shown in other articles published in this Journal, show that the clonal cleaning methods are strongly recommended for cultivars with more than 15 years of ripe stem propagation.

“…Reduced SDM is desirable in animal nutrition, since it is where the largest portion of indegestible fibers -such as cellulose, hemicellulose (Mohammed et al, 2015) and lignin -are often found. However, the fraction of these components plays important role in biofuel production since they are directly linked to the total calorific value produced in these processes (Marafon et al, 2020), a fact that makes the increased SDM yield provided by clonal cleaning methods beneficial and quite interesting.…”

“…Several studies focused on evaluating bioenergy production in recent years have described elephant grass as alternative source for biofuel production (Samson et al, 2005;Rocha et al, 2017) due to its high carbohydrate (Azeke, Eze, Ubong, Kuroshi, 2019) and cellulose contents, as well as to its high biomass production and fast growth (Campos et al, 2019). According to Marafon et al (2020), total calorific value in elephant grass cultivars "Taiwan" and "Cameroon" ranged from 3.905 Kg -1 to 4.047 Kg -1 and from 4.033 Kg -1 to 4.042 Kg -1 , respectively; these values are like those recorded for sugarcane.…”

Elephant grass plays important role in dairy cattle production and has received special attention due to its potential in bioenergy and phytoremediation, as well as to its medicinal properties. The aim was investigating the effects of thermotherapy and meristem culture on elephant grass (Cenchrus purpureus (Schumach.) Morrone) forage production and nutritional value. Cultivars “Mineiro”, “Taiwan A-147” and “Pioneiro” were subjected to the methods: thermotherapy plus meristem culture, meristem culture and mature stems (control). The experiment assessed the tiller number (TN), tiller height (TH), number of leaves/tiller (NLT), leaf/stem ratio (LSR), crude protein (CP), acid detergent fiber (ADF), and neutral detergent fiber (NDF), at three cuts performed every 60 days for 180 days. It was observed beneficial influence on the evaluated traits, which indicated how cleaning methods work. Cultivar “Mineiro”, with more than 20 years of use, was more sensitive to the cleaning methods showing than cultivars “Taiwan A-147” (15 years of use) and “Pioneiro” (less than 10 years). It was observed that methods have affected the NT, TH, SDM, LSR, LDM, CP, and NDF. And, that the cultivars genotype effect in a different way the NT, TH, NLT, SDM, LSR, and CP. Overall, Cleaning methods produced an increase in the evaluated parameters over 100% for the cultivars Mineiro and Taiwan when compared with the traditional method and presented low or negative effect for Pioneiro cultivar This evidenced that the traditional propagation method affects forage production and quality over generations in vegetative propagated species. Basic biotechnology techniques such as meristem culture associated or not with thermotherapy can restore the productive potential being recommended for old asexually propagated cultivars with more than fifteen years of cultivation.
