Embryo Rescue of Aged Cucurbita Pepo Seeds Using Squash Rescue Medium

Pamela Moon and Geoffrey Meru

Abstract

Plant seed is both an important food source and an indispensable propagation material for many cultivated crop species. The ideal conditions required for long-term storage of seeds are expensive, exacting, and not always tenable, particularly for small breeding programs. In most plant species, viability is significantly reduced in old, sub-optimally stored seeds due to depleted energy reserves and biochemical degradation. However, revival of such old germplasm is often desirable for research and germplasm improvement purposes.

Impact of Two Hydrothermal Carbonization Filtrates on Soil Greenhouse Production

Vozhdayev V Georgiy, Kurt A Spokas, Joseph S Molde, Steven M Heilmann, Brandon M Wood and Kenneth J Valentas

Abstract

Hydrothermal carbonization (HTC) is a thermochemical treatment process that allows for the conversion of wet biomass slurries to new liquid and solid products. A majority of the research to date has focused on the solid HTC product (hydrochar). Less attention has been paid to the utilization of the HTC filtrate, which comprises the larger mass fraction of the process.

Classification of Biostimulants Origin Using Amino Acids Composition of Hydrolyzed Proteins

Francesca Baroccio, Nicola Barilaro, Paolo Tolomei and Marcello Mascini

Abstract

The mechanisms of action of biostimulants are multiple and often work in synergy, and then it is not easy to find analytical methods for their characterization. This work provides a practical and fast approach to qualify and classify biostimulants in order to facilitate their control against fraudulent actions.

Impacts of Elevated Carbon Dioxide and Temperature on Physicochemical and Nutrient Properties in Strawberries

Himali N Balasooriya, Kithsiri B Dassanayake, BruceTomkins, Saman Seneweera and Said Ajlouni

Abstract

Strawberry (Fragaria x ananassa Duch.) is one of the most popular edible fruit worldwide. Strawberries are generally cultivated in open fields or under protected cropping, and are available all year round. Consumers prefer fruit with a bright red color, sweet taste, and distinct aroma.Strawberry (Fragaria x ananassa Duch.) is one of the most popular edible fruit worldwide.

Anthocyanin Pigments in Redbud (Cercis spp) Flowers

Penelope Perkins-Veazie, Guoying Ma and Dennis Werner

Abstract

Redbud (Cercis spp.) is used as a spring flowering ornamental tree and is found wild in much of North America. Typically flowers are light purple although there are selected cultigens that are white, rose, or red-purple. Flowers from cultigens common to the eastern U.S. and from wild Eastern redbud (C. canadensis) were collected and tested for color and anthocyanin pigment composition.

Phenotypic Characterization and Evaluation of European Cherry Collections: A Survey to Determine the Most Commonly used Descriptors

Monika Hofer and Daniela Giovannini

Abstract

Standardization of descriptors and protocols is a precondition when aiming to harmonize characterization data records from different plant collections. Improved information on the accessions maintained at the European collections has been a priority target of the Prunus Working Group (WG) of the European Cooperative Programme for Genetic Resources network (ECPGR) since its establishment in 1983.

Expression of Cucumber Green Mottle Mosaic Virus Movement Protein in Cucumber Leads to the Expression Changes of Endogenous Gene

Huawei Liu, Laixin Luo, Pengfei Liu, Chaoqiong Liang and Jianqiang Li

Abstract

Cucumber green mottle mosaic virus (CGMMV) is one of the most important diseases of cucurbit crops. To date the only method available to control this devastating disease is the use of resistant varieties or disease-resistant rootstocks. However, the development of transgenic technology offers the potential to create resistant varieties through the expression of foreign genes. Such approaches are not without risk, and it has been noted that introduction of transgenes can have wide ranging effects, often affecting non-target processes.
