Over the past two decades, Georgia has become one of the largest producers of cultivated blueberries in the United States. As production expanded, several new blueberry yield/quality reducing diseases emerged. The most recent notable disease was Exobasidium leaf and fruit spot, caused by the newly described fungal pathogen Exobasidium maculosum. Although leaf spotting and quality-reducing green spots on fruit had been noted in producer fields for many years prior, it was considered more of a curiosity and not determined to be a production issue.

Machel A. Emanuel received a BSc in Zoology and Botany, an MSc in Plant Production and Protection, and is currently a PhD candidate in Horticulture at the University of the West Indies. His area of research is on the postharvest physiology and biochemistry of tropical fruits.
Machel A. Emanuel won an ISHS student award for the best oral presentation at the III All Africa Horticultural Congress in Nigeria in August 2016.
The rising concept of ecosystem service has highlighted the importance of non-marketed performances delivered by ecosystems. In fruit production, providing acceptable food production levels while preserving natural resources and functions is currently a major challenge, and can be analyzed from the ecosystem service concept perspective. Apple orchards appear to be an interesting study field, as perennial production strongly impacts biogeochemical cycles and pest management within apple orchards deals with both market regulations and reduced use of pesticides.
Flower fertilization and fruit set success in apples depend on the behavior of the pollen tube growth, namely, the pollen tube length after pollination and the time taken to reach the base of the style. Predicting these characteristics will assist in controlling the crop load, by permitting the fertilization of the desired number of flowers and discarding the rest by the use of chemicals which inhibit pollen tube growth prior to fertilization. The main factors affecting pollen tube growth rates are temperature and the resistance of the style tissue.
Olaoluwa Omoniyi Olarewaju obtained his BAgric (Hort) from the Federal University of Agriculture Abeokuta, Nigeria. He is currently a Doctoral Fellow at the University of KwaZulu-Natal, South Africa. His research focuses on identifying pre-symptomatic bio-markers and non-destructive prediction of physiological rind disorders of citrus fruit with a view to identifying innovative techniques of managing postharvest losses in the fresh fruit industry.
Carnations that have various petal colors have been generated not only by conventional cross breeding, but also by bud sport. Flower color mutation by bud sport is thought to occur as a result of periclinal chimaeras or transposons, however, the mechanism is still unknown. To elucidate the mechanism of flower color mutation by bud sport, I used a mutant cultivar group (MINAMI series) showing various petal colors, which had occurred by bud sport. The MINAMI series includes 10 commercial cultivars showing cyanic or acyanic flowers that originated from a pale yellow-flowered genotype.
The important role of cuticular waxes in the defense systems of plants is undeniable. However, very little is known about the chemistry of cuticular wax in the genus Fragaria L. The epicuticular wax crystal morphology was determined using scanning electron microscopy. A wide range of different structures were described. Twelve strawberry genotypes, including ten wild species, one cultivar and one hybrid after wild species introgression, covered the detected range of epicuticular crystal structures.
The aim of this study was to investigate the effect of ethylene absorber (EA) on the postharvest life of bananas. EA could delay the senescence of bananas by reducing ethylene concentrations in storage chambers. Bananas selected for the study were at mature-green stage 2 of ripening, according to the banana ripeness chart (Postharvest Technology Center, UC Davis). Fruit were stored in the presence or absence of sachets of Ethyl Stopper (Bioconservacion S.A., Spain) containing KMnO4 at 20 or 14°C, and 95% relative humidity for 16 days.
The EU-funded research project GoodBerry (www.goodberry-eu.eu) aims to further improve our knowledge of the procedures that facilitate and accelerate the development of well-accepted, desirable and high-quality berry fruits – even under non-favourable growth conditions such as high temperatures.

This research is focused on a new aquaponic system. In principal, aquaponics is the combined production of fish and plants by using the nutrient rich fish water for plant nutrition. Therefore, aquaponics is a system for sustainable food production, especially based on lowering water consumption and associated environmental pollution. Single recirculating aquaponic systems (SRAPS) are well known systems.
Nitrogen status is a well-known key factor for adventitious root formation of ornamental cuttings. Even a slight nitrogen deficiency of stock plants impairs subsequent rooting of cuttings, whereas a surplus can either decrease or increase it. The effect of nitrogen surplus depends on carbohydrate reserves at harvest date and current photosynthetic activity of cuttings during rooting. However, nitrogen status of cuttings cannot be used as parameter for quality assessment of cuttings yet, because established wet-chemical methods are too time-consuming and labor intensive.

The 15th International Peat Congress, with 1,000 participants was excellently organized by the National Committee of the IPS in Kuching, Borneo.
Kuching has a newly built Tropical Peat Research Institute and Borneo has extensive peatlands. They are mainly used as oil palm plantations and agriculture.
The water status of trees can be estimated using Granier-type thermal dissipation probes. However, the method requires determining the maximum temperature gradient (∆Tmax) between the heated probe and the reference probe below. By analyzing the effects of different ∆Tmax determination approaches on sapflow density estimations, the uncertainty of sapflow calculations, which is related to the raw signal processing, was quantified.

Over the last decade there has been an increasing demand for natural products and plant-derived drugs, which are considered by some people to be less toxic and free from side effects when compared to synthetic drugs. With worldwide growing interest in plant derived medicines, there has been a corresponding increase in the demand for raw materials. In vitro culture technology is a suitable method for large scale production of these plants within a short period of time.
ISHS published the 9th edition of the International Code for the Nomenclature for Cultivated Plants (ICNCP) which replaces the eighth edition of the Code which was published in October 2009
Lysophosphatidylethanolamine (LPE) is the breakdown product of a class of phospholipids found in membranes. LPE is an important bio-regulator in plants and animals and has been found to play a critical role in plant growth and development. LPE speeds up ripening and delays aging in plants by two different mechanisms.
