Tillage controls perennial weeds, such as Elymus repens, partly because it fragments their underground storage organs. However, tillage is difficult to combine with a growing crop, which limits its application. The aim of this study was to evaluate how soil vertical cutting with minimum soil disturbance and mowing affect the growth and competitive ability of E. repens in a grass-clover crop. A ...

The increase of atmospheric CO2 due to global climate change or horticultural practices has direct and indirect effects on food crop quality. One question that needs to be asked, is whether CO2 enrichment affects the nutritional quality of Malaysian young ginger plants. Responses of total carbohydrate, fructose, glucose, sucrose, protein, soluble amino acids and antinutrients to either ambient ...

Curcuma longa is well known for its use as spice and medicine. The remarkable feature of the plant is the presence of rhizome, which provides an interesting habitat for association by various groups of bacteria. Some of these associated endophytic bacteria can have growth-promoting effects. In the current study, two species of endophytic Paenibacillus has been identified from the rhizome as ind...

the effects of desiccation and nacl and polyethylen glycol (peg) induced water potentials on rhizome bud sprouting of the perennial weed, glycyrrhiza glabra were investigated in separate laboratory experiments laid out in completely randomized designs. each treatment was replicated four times. the water potentials of nacl and peg used were 0, -0.4, -0.8, -1.2 and -1.6 mpa. desiccation experimen...

Although both rhizome and root of Panax notoginseng are officially utilized as notoginseng in "Chinese Pharmacopoeia", individual parts of the root were differently used in practice. To provide chemical evidence for the differentiated usage, quantitative comparison and metabolite profiling of different portions derived from the whole root, as well as commercial samples, were carried out, showin...

METHODS This pilot cohort trial was conducted at King Abdulaziz University in Saudi Arabia between May and December 2014, among 15 patients with acu...

The aim of the study was to analyse polyphenols compounds from vegetal product Holoschoeni rhizome and its antioxidant capacity in order to justify traditional therapeutic using (livery protect effect). The separation, identification and quantification of polyphenols compounds were made through High performance of liquid chromatography (HPLC), standardized method according USP30-NF25 Monograph....

The important medicinal part of the ginger plant is rhizome. There are several chemical constitutes present in rhizome, in which [6]-Gingerol, [10]-Gingerol, Zerumbone and Shogaols inhibit Colon Cancer, among these [6]-Gingerol and [10]-Gingerol are very important. In the fresh ginger rhizome, the gingerols were identified as the major active components. Gingerol can remain in two form and this...
