'Zheqie 109': A New Ultra-long Purple-red Eggplant Cultivar with Stable Peel Color Adapted to Protected Overwinter Cultivation

Weed management is a major constraint in perennial fruit systems, particularly during establishment when young trees and vines are highly sensitive to competition. Electrical weed control (EWC) is an emerging nonchemical technology, but its suitability in newly planted orchards and vineyards remains unclear.

Soilless substrate stratification entails layering two unique substrates with distinctive physiochemical properties atop each other to improve nursery and greenhouse production sustainability. Most stratified research to-date has explored a 50:50 (v/v) or equal top and bottom stratified depth layer ratio.

The simultaneous improvement of multiple ornamental traits remains a major challenge in Phalaenopsis breeding, and the relationship between floral color phenotypes and quantitative morphological traits is poorly understood. Four hybrid populations of miniature Phalaenopsis were evaluated for floral color segregation and quantitative morphological variation.

Scaevola taccada 'Garden Isle': A New Low Growing Variegated Cultivar for Containers and Landscapes

For rapid determination of whether gray leaf spot disease in field-grown Welsh onion (Allium fistulosum L.) is caused by Stemphylium vesicarium, we targeted the glycerol-3-phosphate dehydrogenase (gapdh) gene and designed specific primers (sv-gpdF/R) that amplify a 194-bp fragment, showing high specificity. In quantitative polymerase chain reaction (qPCR) assays, its sensitivity was 105-fold higher than that of conventional PCR.

Ruidu Hongxin Yihao: A New Table Grape Cultivar with Red Flesh

A New Clematis 'Jadeite'

Hydroponic systems substitute soil with nutrient solutions, making water quality a primary production concern. Because treated municipal water is often too expensive for commercial-scale production, alternative water sources such as industrial process effluents are being explored as cost-effective alternatives. Sugarbeet processing effluent represents one such underexplored source that offers potential for reuse at scale.

The safe deployment of genetically engineered citrus requires evaluation of pollen-mediated gene flow to ensure environmental and regulatory compliance. We assessed the potential movement of the 'D4E1' transgene from transgenic 'US-802::D4E1' trees to the monoembryonic, self-incompatible cultivar US SunGlo under field conditions in Fort Pierce, FL.
