The earliest trace of cannabis use is an archaeological find of hemp textile in China dating from 4000 B.C. (Li & Lin 1974). Hemp thread and rope from 3000 B.C. have also been found in Chinese-occupied Turkestan (Fisher 1975). The Rh-Ya (500 B.C., but pointing back many centuries earlier) mentions its use for fiber (Bouquet 1950), as do the Shih-Ching (lOth-7th centuries B.C.), the Li-Chi (100 ...

Cannabis sativa L. is an important herbaceous species originating from Central Asia, which has been used in folk medicine and as a source of textile fiber since the dawn of times. This fast-growing plant has recently seen a resurgence of interest because of its multi-purpose applications: it is indeed a treasure trove of phytochemicals and a rich source of both cellulosic and woody fibers. Equa...

This study was conducted to examine Florida consumers’ stance on legalizing the growing and processing of hemp, recently redefined as an agricultural commodity. Factors were explored that may explain their provide insight into communication needs in early stages U.S. hemp industry revival. Results indicated respondents who had more favorable attitudes toward also likely fall within category bei...

In this study, an adsorption process using hemp-based materials in felt form was applied to remove between 45 and 53 contaminants present wastewater from the surface treatment industry. Several were compared batch experiments, including a made of 100% hemp fiber (HEMP), same cross-linked with 1,2,3,4-butanetetracarboxylic acid (HEMPBA), coated maltodextrin-1,2,3,4-butanetetracarboxylic polymer ...

Industrial hemp (Cannabis sativa L.) is traditionally processed for its high fibre content in the textile industry, but recent years, it has come to constitute a new raw material food industry. Hemp seeds, also seed meal, are rich protein (25%) and oil (30%), latter consisting of 80–90% unsaturated fatty acids; they represent balanced nutritional source replace classic animal sources, used indu...

Aminomethylphosphonic acid (AMPA) is the most frequently detected metabolite of glyphosate in plants. The objective of this study was to determine if there is any correlation of metabolism of glyphosate to AMPA in different plant species and their natural level of resistance to glyphosate. Greenhouse studies were conducted to determine the glyphosate I 50 values (rate required to cause a 50% re...

Two experiments were conducted in north-central Florida to examine the effects of various winter cover crops on plant-parasitic nematode populations through time. In the first experiment, six winter cover crops were rotated with summer corn (Zea mays), arranged in a randomized complete block design. The cover crops evaluated were wheat (Triticum aestivum), rye (Secale cereale), oat (Avena sativ...

BACKGROUND Previous research focused on pretreatment of biomass, production of fermentable sugars and their consumption to produce ethanol. The main goal of the work was to economise the production process cost of fermentable sugars. Therefore, the objective of the present work was to investigate enzyme hydrolysis of microcrystalline cellulose and hemp hurds (natural cellulosic substrate) using...
