The avocado plant (Persea Americana Mill.) is a medicinal and belongs to the Lauraceae family which has many properties. Avocado skin contains flavonoid compounds that can be used protect reduce damage due UV rays. active substances contained in americana are flavonoids quercetin. In sample on quercetin as standard solution from peel for avocado. This study aims determine levels of antioxidant ...

B and Phomopsis/Diaporthe (P/D) spp. are fungal pathogens known to cause cankers on a variety of woody hosts such as avocado, grapevine, almond, citrus, cherry, plum, mango, and coast live oak. On avocado (Persea americana Mill.), the disease came to be known as Dothiorella canker because the pathogen most often isolated at the time was known as Dothiorella gregaria (2). However, new research h...

The uibiquitouis occturrence of hydrocarbons including mlany aromiatics in plants has been the subject of ain extensive, careful review (2). However. the origin andI metabolisnm of the aromatic hydrocarbons in plaint tissue has received little attention. The intriguilng possible biogenesis of aromatics from the prevalent lpolyacetylenes in plants has been suggested (7). P'reviouis reports from ...

Research has been on-going on many plant materials, especially those discarded as waste, to exploit their nutritional and antinutritional properties. This is as a result of the United Nations’ millennium development goal to eradicate extreme poverty and hunger. Avocado (Persea americana Mill) seeds are often discarded after taking the pulp of the fruit. This study is aimed at evaluating the eff...

Persea schiedeana, a close relative of avocado (Persea americana), is an important part of agroforestry systems and diets in parts of Mesoamerica, particularly in the coffee growing areas of southeastern Mexico and Guatemala, where it is known as chinene, coyo, and yas. Little research attention has been given to this species, other than as a rootstock for avocado. Research carried out in six v...

The potential involvement of C7 sugars as antioxidants in various avocado tissues was tested. Total antioxidant activity was found to be similar in leaf, exocarp and seed tissue; however, the concentration of total antioxidants in mesocarp tissue was lower than in other tissues at all three sampling dates. The various tissues examined had different predominant antioxidant systems; while leaf ti...

An undescribed cecidomyiid was discovered in Miami-Dade Co., Florida, during a survey for predators of the avocado lace bug, Pseudacysta perseae (Heidemann), a native pest of avocados, Persea americana , and redbay, Persea borbonia , in the USA. The avocado lace bug was considered a minor pest of avocados until the mid-1990s. Persistent outbreaks of this insect have been observed in Florida and...

The utilization of organic wastes to improve soils or for growth media components in local farms and nurseries can reduce the environmental pollution linked to waste disposal while increasing the sustainability of crop production. This approach could be applied to waste products generated from the production of guacamole (an emerging activity in the avocado production areas in mainland Spain), ...

Tetraleurodes perseae Nakahara (Hemiptera: Aleyrodidae) is an exotic whiteßy in California that is aminorpest of avocados,Persea americanaMiller (Lauraceae). Fieldmonitoringover a 4.5-yr period (1997Ð2002) in a commercial avocado orchard in southern California indicated that T. perseae is probably univoltine, and adult densities show single distinct peaks each year around August. The only hymen...

These findings could be interpreted as implying that the enhancement by carcinogens in vitro of hamster hepatic microsomal biphenyl 2-hydroxylase (McPherson ‘et al., 19746) is mediated through an effect on the microsomal membrane rather than via direct specific conformational modification of the biphenyl 2-hydroxylase enzyme itself. In an attempt to differentiate between the soluble and microso...
