Assessing the Socioecological Perspectives of Eucalyptus Cultivation and Plantation Expansion in Laos

Xayphanya Chanthalath, Liu Yong, Mukete Beckline, Southdavone Inthilath
In Laos, the cultivation of fast growing trees as eucalypts has been promoted due to a rapid decline in natural forest cover. However, this expansion of fast growing trees might not end in a win-win situation for both humans and the environment. This paper examines the social and ecological potentials of Eucalyptus (Eucalyptus

Ionic Liquid Based Ultrasonic-Assisted Extraction of Oleanolic Acid from Grape Seeds

Xifeng Zhang, Xue Li, Qian He, Bin Zhang, Xue Zheng
Ionic liquid based ultrasonic-assisted extraction (ILUAE) was successfully applied to extract Oleanolic acid (OA) from grape seeds. Different kinds of 1-alkyl-3-methylimidazolium ionic liquids with different kinds of cations and anions were studied and 1-butyl-3-methylimidazolium chloride ([C4mim]Cl) solution was selected as extractants. The optimal conditions of ILUAE were determin

Impact of Different Methods of Soil Sampling and DNA Extraction on the Identification of Soil Bacterial Abundance under Elevated CO2

Fengxia Li, Saman Bowatte, Paul C. D. Newton, Dongwen Luo
Elevated atmospheric CO2 (eCO2) is anticipated to have marked effects on soil microbial populations. While there is experimental evidence to support this view there are also studies where changes in microbial populations, such as the abundance of bacteria, are suggested but cannot be statistically established. We conducted this study

Suitable Hybrids and Synthetics Provitamin A Maize Selected for Release in the Democratic Republic of Congo

Kabongo Tshiabukole, Pongi Khonde, Mbuya Kankolongo, Tshimbombo Jadika, Kaboko Kasongo, Mulumba Badibanga, Tshibanda Kasongo, Kizungu Vumilia
Six new provitamin A hybrids (LY1001-14, LY1001-22 and LY1001-23,) and synthetic maize varieties (PVASYN13, PVASYN9 and PVASYN7) were tested for their agronomic performance and compared to a locally adapted improved open pollinated variety (SAMARU) in the central and western conditions of DRC. A randomized complete block experiment with four replications was used. Following data were collected: 50% male and female flowering, plant

Responses of Maize Landrace Seedlings to Inoculations of Fusarium spp.

Dolores Briones-Reyes, Fernando Castillo-González, Carlos de León-García-de-Alba, Antonio Ramírez-Hernández, Víctor Heber Aguilar-Rincón, José Luis Chávez-Servia
To assess the reaction of maize landrace seedlings to inoculations of Fusarium spp. derived from different geographic origins, inoculations were performed to substrates in which seeds were germinated, and the severity of damage and the degree of resistance and/or tolerance at the seedling stage were later evaluated. In this study, 57 populations of maize were co

Influence of Tillage and Wood Ash on Zn and Fe Content of Soil, Castor Shoot and Seed

I. A. Nweke, C. N. Mbah, S. I. Ijearu
The effect of tillage methods (Mound, Ridge, Flat) and rates of wood ash on soil properties and yield of castor bean plant were studied in field trial at Abakaliki for 3 years cropping seasons. The experiment was a split plot in randomized complete block design with three tillage methods and four rates of wood ash (0 t·ha﹣1, 2 t·ha﹣1, 4 t

Influence of Harvest Season and Maturation of Different Sugarcane (Saccharum Spp.) Cultivars on the Chemical Composition of Alembic Brazilian Sugarcane Spirit

Oscar William Barbosa Fernandes, Débora Faria Silva, Ananda Lima Sanson, Mauricio Xavier Coutrim, Robson José de Cássia Franco Afonso, Paulo Eichler, Fernando Santos
Contrary to the ethanol industrial production, the quality and composition of sugar cane as raw material for the production of alembic cachaca have until now not been completely addressed. This work evaluated the influence of five different sugarcane cultivars and degree of maturation over the physicochemical composition of cachaca produced under strict controlled conditions. Three harvest seasons were used in order to obtain diff
