the reaction of four field tomato cultivars (super strain b, super chief, mobil, and royal) along with two greenhouse cultivars (polaris and es 1002 f1) was evaluated agianst m. javanica under greenhouse conditions. the soil around tomato seedlings (bearing 5-6 leaves) was inoculated with two levels of the nematode inoculum i.e. 1000 and 2000 eggs as well as second stage juveniles per every kg ...

Long-term exposure to music allows us to develop an implicit knowledge of musical syntax and this knowledge serves as the foundation of musical expectation. Expectation violations are an important part of musical experience and give music an “ebb and flow” that keeps listeners interested. Regardless of how many times we listen to a song, when we are confronted with a syntax violation in the son...

Spotted wilt virus disease caused by Tomato spotted wilt tospovirus (TSWV) has become a limiting factor in peanut (Arachis hypogaea L.) production in the Southwest region of the U.S. Selected peanut cultivars (Okrun, Southwest Runner, Tamrun-98, Tamrun-96, Georgia Green, Tamrun OL-02, Tamrun OL-01, and Georgia Hi Oleic) were evaluated for reaction to TSWV in field plots in 2001, 2002, and 2003....

Ten cultivars and 13 germplasms of white clover (Trifolium repens) were evaluated in the greenhouse for resistance to the southern root-knot nematode, Meloidogyne incognita race 4. One hundred plants of each cultivar or germplasm were rated for percentage of the root system galled (PRSG) at 60 days after inoculation with root-knot nematode eggs. Tillman (9%) and SRVR (19%) had the highest perce...

Many important high quality cultivars are becoming increasingly susceptible to the scab pathogen. Two such cultivars, 'Stuart' and 'Desirable', comprise over one half of Georgia's total pecan acreage. This increasing susceptibility has often been attributed to the increased prevalence of once rare races of scab that are able to infect these cultivars. Demaree and Cole (1929) were the first to d...

This investigation was carried out with the aim of determining the effect of polyethylene glycol 6000 (PEG; 0, 3%, 6% and 9% w/v) treatment on six cultivars of Medicago sativa. PEG treatment significantly decreased the germination index in cultivars of Isfahani, Hamedani, Bami, Baghdadi, Yazdi and Ghare-Medicago, with the highest reduction in Ghare-Medicago and Hamedani cultivars by about 50% a...

Twenty-two different herbaceous perennials were studied for their reaction to separate inoculations of Meloidogyne arenaria and M. incognita under greenhouse conditions. Perennial taxa that did not develop root-galls following inoculation, and therefore are considered as nonhosts of both nematode species, included species and cultivars of Aethionema, Fragaria, Phlox, and Polygonum. Echinacea, M...

Aphelenchoides besseyi is a seed-borne plant parasitic nematode and is widely distributed in most rice growing areas. Application of resistant cultivars requires the identification of resistance source, which can then be included in breeding programs to improve the local rice cultivars. Fourteen Iranian rice genotypes including improved and local varieties were evaluated for resistance to A. be...

The resistance phenotypes of nine potato cultivars to five isolates of Alternaria solani, causal agent of early blight, were studied after inoculation and growth under greenhouse conditions. We identified potato cultivars with both susceptible and resistant phenotypes as well as A. solani isolates with varying degrees of aggressiveness. Two potato cultivars and two pathogen isolates were select...
