Different organic materials possessing antimicrobial properties have the ability to retard nitrification. Nitrification retarders could be successfully used to improve fertilizer efficiency if the retarders do not increase ammonia volatilization as well. The main objective of this study was to find whether any locally available organic materials namely cow dung, seed crush of Syzygium cumini, L...

The effect of feed supplementation with natural α-tocopherol, rosemary, green tea, grape seed and tomato extracts on the oxidative stability of broiler meat was investigated by measuring lipid oxidation, protein oxidation and α-tocopherol content of breast muscle. Supplementation with α-tocopheryl acetate at a dietary concentration of 200 ppm was used as a control. The broilers were fed a diet ...

BACKGROUND Tea seed oil is a high quality edible oil, yet lacking sufficient scientific evidences to support the nutritional and medical purposes. We identified major and minor components in Camellia tenuifolia seed oil and investigated the antioxidative activity and its underlying mechanisms in Caenorhabditis elegans. PRINCIPAL FINDINGS The results showed that the major constitutes in C. ten...

The kinetics of the extraction of tea seed oil with supercritical CO2 was studied. A kinetic model of the extraction of tea seed oil using supercritical CO2 was developed on the basis of the differential mass balance to simulate the extraction process. The model could simulate the distribution of the solute concentration in CO2 inside the extraction bed as a function of extraction time and heig...

Gyropsylla spegazziniana (Paraguay tea ampul) is one of the most important pests of Paraguay tea plants, and prohibition of synthetic insecticide use for control of this pest has led to the search for alternative methods. This laboratory study aimed to compare different control strategies for G. spegazziniana, utilizing a commercial neem seed oil product. Paraguay tea seedlings were treated wit...

Aluminum (Al) accumulation and long-distance transport in oil tea (Camellia oleifera Abel.), known to be an Al accumulator, was investigated. The average Al concentration in the embryo of oil tea seeds was 389 mg Al kg(-1) dry weight, which was higher than seeds of other Al accumulators. By partially suppressing leaf transpiration in the field, Al accumulation in leaves was depressed, which cla...

Male fertility of crop plants is a function of pollen production and viability. In breeding, it is a requirement that there be similar fertilities among breeding parents within seed orchards. An in-vitro germination method was used in this study to determine variation in pollen viability among eight tea (Camellia sinensis) genotypes, over three flowering seasons in four isolated biclonal seed o...

BACKGROUND One of the important reasons behind termination of breast-feeding in the first six months after childbirth is insufficient production of breast milk. OBJECTIVES The aim of this study was to determine the effect of herbal tea containing fenugreek seed on the signs of breast milk sufficiency in Iranian girl infants aged 0 - 4 months, at the medical health centers of Tehran university...
