The pink hibiscus mealybug, Maconellicoccus hirsutus (Green), is a highly polyphagous pest that invaded southern Florida in 2002 and is now widely established throughout most of the state. Although Hibiscus rosa-sinensis L. is a preferred and economically important host of M. hirsutus , the susceptibility and expression of feeding symptoms by different cultivars have not been evaluated. Cultiva...
Viral neuraminidase inhibitors are widely used as synthetic anti-influenza drugs for the prevention and treatment of influenza. However, drug-resistant influenza A virus variants, including H5N1 highly pathogenic avian influenza viruses (HPAIVs), have been reported. Therefore, the discovery of novel and effective antiviral agents is warranted. We screened the antiviral effects of 11 herbal tea ...
Locally, Gomutra Silajit is known under the name “RAKTAMANDALAM”. Literally, it means ‘Blood Patch’ or ‘Blood coloured Matter’. In fact, the Ayurvedic texts refer to its colour as that of ‘Japakusuma’ – the China Rose, botanically known as Hibiscus rosasinensis Linn. (Telegu: Mandara). For this reason the local name referring to its colour as ‘Rakta’ (Blood) is apt. The above treatise also indi...
Competition among pollen grains for the chance to fertilize ovules typically involves two stages: arrival times on stigmas and/or the growth of pollen tubes through styles. In a previous study of Hibiscus moscheutos, we found that individual pollen donors often differed in pollen tube competitive ability. Here we determined whether short delays in pollen arrival time altered the average success...
Scarlet rosemallow (Hibiscus coccineus Walter) is a diploid, perennial, erect, and woody shrub. The species is a desirable inclusion in home landscapes because it is a native plant with attractive flowers and unusual foliage. The objective of these experiments was to determine the number of loci, number of alleles, and gene action controlling flower color (red vs. white) in scarlet rosemallow. ...
A three-way resolution method based on PARAFAC model was applied for the UV-Vis spectra to study the simultaneous degradation of anthocyanins extracted from fresh calyces of flowers of the Hibiscus sabdariffa. This methodology was used to resolve a chemical system, for which there was no a priori information about the composition or the pure spectra, a so-called black system. In the pH range fr...
—Seed predation has the potential to strongly reduce seed production and thereby act as a selective force on the evolution of flowering traits and other defenses against herbivory. We characterized levels of predispersal seed predation on Hibiscus moscheutos (Malvaceae) during 2001 and 2002 at four sites in Ohio and Maryland, USA. The seed predators were a weevil, Conotrachelus fissinguis (Cole...
The present study is designed to investigate the hypolipidemic effect of ethanolic extract from the leaves of Hibiscus sabdariffa L. (HSEE) in hyperlipidemic rats. In the present work, HSEE was evaluated at three doses (i.e. 100, 200 and 300 mg/kg, orally) in cholesterol-induced (2 g/kg, orally) hyperlipidemic Wistar rats. Atorvastatin (10 mg/kg, orally) was used as the standard drug. Administr...
effect of adding hibiscus sabdariffa (hs) in diet on performance and immune response of broilers was examined during aflatoxicosis using a total of 192 day-old ross 308 male chicks in a completely randomized design with four treatments, four replicates and 12 chicks per each replicate. treatments were include: 1. negative control (without additives), 2. positive control (2.5 mg aflatoxin b1/kg)...
