When staining the internal phloem region of a potato tuber with the vital stain neutral red, it was observed that files of elongated cells of narrow diameter were heavily stained and were easily distinguishable from the more isodiametric parenchyma cells, many of which did not stain with neutral
1. The hatching factor of the potato-root eelworm was concentrated from potato-root leachings by adsorption on charcoal. The crude material, extracted from charcoal with acetone, was purified by partition between ethyl acetate and m-potassium dihydrogen phosphate, and ethyl acetate and a solution of
A rapid, reliable method has been developed for the multi-residue analysis of aniline metabolites of chlorpropham in potato samples. The method involves the precolumn derivatization of aniline metabolites with 5-(4,6-dichloro-s-triazin-2-ylamino) fluorescein (DTAF) and their subsequent separation
The present study was undertaken to examine the protective effects of an anthocyanin fraction (AF) obtained from purple-fleshed sweet potato on acetaminophen (paraceptamol [APAP])-induced hepatotoxicity in mice and to determine the mechanism involved. Mice pretreated with AF prior to APAP
Potato (Solanum tuberosum L.) is considered as one of the most economically important non-sugar food crops in Mauritius, with annual production of over 14,000 tonnes (Statistics Mauritius 2018). In September 2019, in a seed potato field located in St Pierre, approximately 10% of tubers showed
The cultivated potato Solanum tuberosum L. is an autotetraploid with Endosperm Balance Number (EBN) of 4. There are some allotetraploid 2EBN wild species with desirable traits for potato improvement. However, it is very difficult to cross between these two groups due to differences in EBN. Eleven
Presence of higher enzyme levels of aminopyrine N-demethylase, aniline hydroxylase and 11-beta hydroxylase activities were observed in Cunninghamella blakesleeana grown in potato-dextrose medium for 96 h. The enzyme activity preferred NADPH as a cofactor and showed inhibition with CO, indicating
BACKGROUND
Acrylamide (AA) is an important industrial chemical primarily. AA is also found in carbohydrate-rich foods that are prepared at high temperatures, such as French fries and potato chips. It is demonstrated that AA is a carcinogen and reproductive toxin and has ability to induce sperm
Watermelon is one of the major crops grown in Mexico and represents 4% of the total cultivated area with fruits in this country. In 2013, Sonora State was ranked second in the production of watermelon at a national level. Fungal and oomycete diseases are among the main biotic factors affecting
Osteospermum (African Daisy or Cape Daisy) is a genus belonging to the Calendulae with a large number of perennial plant species. In February of 2007, a severe damping-off occurred on 3- to 4-month-old potted cuttings of Osteospermum 'Impassion Rose Purple', 'Impassion White', 'Impassion Purple',
Lagunaria patersonii (Adr.) G. Don (cow itch tree) is native to Australia and tolerates salted winds. During July 2007, damping-off of cow itch tree was observed on 4-month-old seedlings growing in a commercial nursery in eastern Sicily, Italy. More than 20% of the seedlings showed disease symptoms.
Common garden petunias (Petunia × hybrida Hort. Vilm.-Andr.) are herbaceous annual plants with brightly colored flowers up to 10 cm in diameter. During the winter of 2002, crown and root rot were observed on plants (cv. Ultra) growing in five greenhouses in Buenos Aires. Affected plants were
Brown ring patch was first described as a disease of cool-season turfgrass on creeping bentgrass (Agrostis palustris) (4) in Japan and later reported in California on annual bluegrass (Poa annua) (2). Brown ring patch symptoms were observed beginning in December 2007 through spring 2008 on 6 of 18
