This result is significantly different from that of Variyar, Pendharkar, Banerjeea, and Bandyopadhyay and therefore deserves further study. Black pepperPiper nigrum L. The humid tropical evergreen forest bordering the Malabar Coast Western Ghats is one of the hot spot areas of plant bio-diversity on earth is its center of origin and diversity.

However, the crop faces constraints like rampant fungal and viral diseases, lack of disease free planting material, hence biotechnological tools can be utilized to address these problems and strides have been made successfully. The standardization of micropropagation, somatic embryogenesis, in vitro conservation, protoplast isolation, and genetic transformation protocols are described here.

The protocols could be utilized to achieve similar goals in the related species of Piper too. Studies on the interactions of Meloidogyne incognita, Radopholus similis and Fusarium solani on black pepper Piper nigrum L. This study on the interactions between various cultivars of the black pepper plant Piper nigrum L. Directory of Open Access Journals Sweden. Full Text Available This paper reviews the role of Natural Farming as an ecological farming method to produce organically grown food of safe and high quality and at the same time improve soil quality and soil health.

Currently, there is a dearth of information on the effects of Natural Farming approach on black pepper farms particularly in Sarawak, Malaysia. Previous studies on other crops had indicated positive outcome using the Natural Farming method. Thus, this paper discusses the essential role of effective microorganisms in Natural Farming and their potential in pepper cultivation. Through the action of effective microorganisms, this approach should be able to transform a degraded soil ecosystem into one that is fertile and has high nutrients availability.

The mixed culture of effective microorganisms applied must be mutually compatible and coexist with one another to ensure its favorable establishment and interaction in the soil. Therefore, it is anticipated that introducing Natural Farming in black pepper cultivation can enhance the predominance of effective microorganisms in the soil, which in turn could lead to promising growth and yield of the crop.

Application of microwaves for microbial load reduction in black pepper Piper nigrum L. The present study investigates the use of microwave MW radiation for microbial load reduction in black pepper and analyses the effect on quality. Black pepper was exposed to MWs at two different power levels and W at an intensity of 40 W g -1 for different time intervals min and moisture content and g kg -1 on a wet basis.

The exposure of black pepper to MWs at W for The retention of volatile oil, piperine and resin was These results suggest that MW heating can be effectively used for microbial load reduction of black pepper without a significant loss in product quality. Growth and survival of Salmonella in ground black pepper Piper nigrum. The aw threshold for growth was determined to be 0. At high relative humidity, aw increased to approximately 0.

Results of this study indicate Salmonella can readily grow at permissive aw in ground black pepper and may persist for an extended period of time under typical storage conditions. Published by Elsevier Ltd. Structural and sensory characterization of key pungent and tingling compounds from black pepper Piper nigrum L.

To gain a more comprehensive knowledge on whether, besides the well-known piperine, other compounds are responsible for the pungent and tingling oral impression imparted by black pepperan ethanol extract prepared from black pepper Piper nigrum L. Sensory studies by means of a modified half-tongue test revealed recognition thresholds ranging from 3. Chemistry and in vitro antioxidant activity of volatile oil and oleoresins of black pepper Piper nigrum.

Essential oil and oleoresins ethanol and ethyl acetate of Piper nigrum were extracted by using Clevenger and Soxhlet apparatus, respectively. GC-MS analysis of pepper essential oil showed the presence of 54 components representing about The major component of both ethanol and ethyl acetate oleoresins was found to contain piperine The antioxidant activities of essential oil and oleoresins were evaluated against mustard oil by peroxide, p-anisidine, and thiobarbituric acid.
