Naturally occurring disease-suppressive soils have been documented in a variety of cropping systems, and in many instances the biological attributes contributing to suppressiveness have been identified. While these studies have often yielded an understanding of operative mechanisms leading to the suppressive state, significant difficulty has been realized in the transfer of this knowledge into ...

the flowering phase of apple trees is the most critical step in relation with low temperatures and frost events. therefore, forecasting the time of flowering is important. if a model can predict the exact time of flowering, it would be feasible to care for flowers agianst late spring freezing (lsf). in this study, we evaluated three temperature-base chilling models namely: chilling hours (ch), ...

OBJECTIVE AppleBreed DataBase (DB) aims to store genotypic and phenotypic data from multiple pedigree verified plant populations (crosses, breeding selections and commercial cultivars) so that they are easily accessible for geneticists and breeders. It will help in elucidating the genetics of economically important traits, in identifying molecular markers associated with agronomic traits, in al...

The University of Vermont Apple Program received a USDA grant to study the long-term effects of “particle film technology” on Northeast apple orchards. This technology has been commercially available to growers since 2001 in the kaolin clay–based product Surround. Surround is viewed as a potential alternative for some organophosphate uses in orchards. It is considered a “Reduced Risk Pesticid...

OBJECTIVE Many species of plants present noticeable potency against human bacterial and fungal pathogens. MATERIALS AND METHODS In the current study, antimicrobial activity of the fresh fruits of 4 cultivars (A to D) of Malus domestica cultivated in the Qamsar area of Kashan, Iran was investigated. The disk diffusion and minimal inhibitory concentration (MIC) evaluation antimicrobial activity...
