Two populations of Cucurbita were studied for the inheritance of corolla pigments. Flowers from them were collected--classified as orange, yellow, or cream--and analyzed for total carotenoid pigments. In most cases, chemical analysis for total pigments agreed with observed color designations. The ? 2 and backcross results fitted the expected 1:2:1 and 1:1 segregations, respectively, found in th...

In a host-range study carried out under greenhouse conditions, a total of 37 commercial fruit tree, grape, and citrus rootstocks were tested for their reaction to a population of the lesion nematode, Pratylenchus vulnus, in Spain. Twenty-five rootstocks had a Pf/Pi > 1.5. These included almond (Desmayo Rojo, 1143), apple (EM-9, EM-106), avocado (Hass), cherry (Santa Lucia 64, Camil, M x M 14, M...

The Citrus tristeza virus (CTV) strains present in an area can determine the type and severity of disease produced. Using real time RT-qPCR, we screened a series of representative samples collected throughout Florida from 1964 to 2002 for CTV strain presence. We found that contrary to previous reports, the historical samples were infected with both the T30 and T36 strains, the latter often at l...

As olfactory perceptions vary from person to person, it is difficult to describe smells objectively. In contrast, electronic noses also detect smells with their sensors, but in addition describe those using electronic signals. Here we showed a virtual connection method between a human nose perceptions and electronic nose responses with the smell of standard gases. In this method, Amorphophallus...

Drought is among the most crucial limiting factors for crop production and considered a major threat to food security. Rootstock selection an important approach drought management. This research was aimed study responses of rootstocks against stress examine impacts melatonin application on these rootstocks. Carrizo citrange, fying dragon, sour orange were selected current study. To test stress,...

BACKGROUND The perception of sour taste in humans is incompletely understood at the receptor cell level. We report here on two patients with an acquired sour ageusia. Each patient was unresponsive to sour stimuli, but both showed normal responses to bitter, sweet, and salty stimuli. METHODS AND FINDINGS Lingual fungiform papillae, containing taste cells, were obtained by biopsy from the two p...

Yogurt is one type of fermented dairy that has a fresh sour taste. This drink contains probiotic bacteria can improve digestive health. The nutritional content yoghurt be enriched by adding other herbal food ingredients, for example, cica leaf extract and rosella flower. study tested the effect addition pegagan flowers on acidity yogurt. Experimental research methods using Complete Random Desig...

OBJECTIVE To verify the influence of sour taste on swallowing and the presence of reflex cough when sour material was swallowed in patients with dysphagia secondary to brain injury. METHOD Fifty dysphagic brain injury patients who underwent videofluoroscopic swallowing study (VFSS) were recruited. The patients who had shown severe aspiration at 2 ml of liquid were excluded. The dysphagic pati...

Sour taste is detected by a subset of taste cells on the tongue and palate epithelium that respond to acids with trains of action potentials. Entry of protons through a Zn(2+)-sensitive proton conductance that is specific to sour taste cells has been shown to be the initial event in sour taste transduction. Whether this conductance acts in concert with other channels sensitive to changes in int...

Acetonic extracts of melon pumpkin, Cucurbita maxima (Duchesne), Sweet Orange, Citrus sinensis (L.) and Sour Orange, Citrus aurantium (L.), were evaluated for insecticidal activity against adults of three stored product pests viz., Sitophilus oryzae (L.), Rhyzopertha dominica (Fabricius) and Tribolium castaneum (Herbst), by filter paper diffusion method (direct contact application) and fumigati...
