Papaya (Carica papaya L.) is a tropical fruit crop originating from Central America and Mexico. Its remarkable productivity, early bearing and nutritional value are popular attributes justifying production in many areas; the crop ranks third place among the most produced tropical crops in the world, after banana and mango. Spain is the first producer of tropical fruit in Europe, leading the production for bananas, mangoes, avocados, cherimoyas and loquat.
I am Branimir Njezic, a PhD student at the University of Banja Luka, Faculty of Agriculture, Bosnia and Herzegovina. I am in the last year of my PhD thesis supervised by Prof. Dr. Ralf-Udo Ehlers. I work on biological control of the most important pests of plum (plum sawflies, Hoplocampa flava and H. minuta) using entomopathogenic nematodes (EPN). The only currently available measure for farmers to control plum sawflies are synthetic insecticides. They are applied at the time of petal fall, when beneficial organisms are present in the orchards.
The 'Khzandeh' system is one of the traditional systems for grape training in Iran. In this system, the roots of the plants are laid down in a trough (depth: 80 cm and width: 100 cm), and the trunk is placed on a small mound formed after digging the streams. The amount of water used in this system is considerable, and the time of the last irrigation and harvesting in this method is more important than for other systems.
Climate change has become a major challenge in modern agriculture because of its negative impact on both quantity and quality of the crops. Rising atmospheric temperatures and CO2 concentrations appear to have direct and indirect effects on the nutritional quality of fruits and vegetables. However, most studies evaluated the effect of either temperature or CO2 concentration, but not their combination. Strawberry (Fragaria × ananassa Duch.) is well known for its high phytochemical content and proven health benefits.

The rose rosette task force compiled the rose virome in 2016 and twenty-four viruses have been reported worldwide to infect roses. These viruses can reduce yields of garden roses because they cause damage to roses even before visible symptoms develop. Therefore, early viral infections may not be diagnosed until symptoms break out or fully develop in the plant. Common and frequently used detection of viral diseases affecting roses are serologically based, such as ELISA, or alternatively, lateral flow devices.
Chestnut (genus Castanea, family Fagaceae) has spread to different regions of the northern hemisphere, over many centuries. Since ancient times, 13 species of the genus have had an important place in human nutrition. Major areas where these species are concentrated include: China, Korea, Japan, Turkey, southern Europe and North America. Castanea sativa, which also contains Anatolian chestnut, is a native species of the Mediterranean basin.
In the field of plant physiological ecology, people are usually interested in how leaf carbon and water dynamics determine whole plant performance, including growth and reproduction, with stems being the organ responsible for water transport and mechanical support. In many plants from arid and semi-arid ecosystems in both temperate and tropical regions, green photosynthetic stems have evolved in many species, possibly as a response to water shortage at least during one period of the year, yet the possible advantages that green stems confer to such species remain unclear.
Currently, the majority of extensive green roofs are planted solely with species from the genus Sedum. These plants are extremely drought tolerant but are not as efficient at providing ecosystem services as other potential green roof vegetation. For example, taller species with wider leaves are more efficient at reducing storm water runoff and substrate temperatures than the short succulent Sedum species. However, this does not necessarily mean that Sedum should be excluded from green roof vegetation.

Lilium (commonly known as lily) is one of the most important bulbous flower genera belonging to the family Liliaceae, and is native to temperate regions of the northern hemisphere. It is used for cut flower production, pot plant production and landscaping purposes. Each year the interest in lilies increases around the world. Presently they hold the fourth position among cut flowers in world flower trade. Pollen is a unique plant tissue that potentially can be used and manipulated to the advantage of the geneticist, breeder, physiologist and germplasm curator.
Apricot (Prunus armeniaca L.) is a temperate fruit species cultivated in more than 60 countries. In recent years, an important renewal of plant material is taking place worldwide. Traditionally, pollination requirements have not been considered important because most cultivars in Europe were self-compatible.

European hazelnut (Corylus avellana L.) is an economically and nutritionally important nut crop with wild and cultivated populations found throughout Europe and in parts of Asia. Turkey is the world's main hazelnut producer with 450,000 tons grown on 701,141 ha, accounting for 65% of world production.

India contributes 69% of global mango production. However, availability of fruit in India meets only 50% of demand. In order to overcome the problems of post-production losses, several strategies, such as the best harvesting and handling practices, are being promoted. However, the recommended practices are not being adopted because of practical difficulties. This situation requires a simple and practical solution to a challenging problem.
The use of artificial light has become very common as a means to increase production and quality of seedlings. Light-emitting diodes (LEDs) are a new source of economical and spectrally-selective light. The benefits are: versatility in handling and mounting, long life expectancy, wattage use efficiency and lower heat production.
This project investigated the effects that different rates of nitrogen fertigation had on red drupelet disorder expression in commercial blackberries. Red drupelet disorder (sometimes known as red drupelet reversion or reddening) is a postharvest physiological disorder that causes fruit, which is black at harvest, to revert to a red colour following cold storage. This causes a mottled appearance on the fruit that is off-putting to the consumer and can render fruit unmarketable in some cases, causing significant financial loss to producers.
Morphological, physiological, biochemical and molecular changes occur during the in vitro tissue culture process of plants. It is hypothesised that the tissue culture process restores juvenile characteristics to explants obtained from physiologically mature mother-plants. Also, restoration of juvenile characters in mature mother plants is believed to be helpful for in vitro regeneration, especially for recalcitrant woody perennials. However, the above hypothesis has not been tested using molecular biological techniques.
Consumption of African leafy vegetables (ALVs) has increased in Kenya, especially within urban and peri-urban areas. ALVs, such as vegetable amaranth (Amaranthus cruentus L.), are rich in bioactive compounds, e.g. protein, minerals, vitamins, dietary fiber, carotenoids and phenolic compounds, which play an important role in health promotion. However, ALVs are highly perishable; hence they suffer significant postharvest losses. The use of ultraviolet light C (UV-C) is gaining interest in improving postharvest quality and hygienic status of fruits and vegetables.
The purpose of this study was to investigate the use of sequencing technology and in silico polymorphism analysis to increase the efficiency of development of polymorphic SSR markers in papaya. We performed whole-genome re-sequencing on two commercial cultivars of papaya, 'Sunrise Solo' (Hawaiian cultivar) and 'RB2' (Australian cultivar), to identify a range of polymorphic sites to facilitate marker-assisted breeding programs for improving fruit quality traits.
Since 1991, fruit and vegetable production has been expanding in Uzbekistan. Although national supply should be sufficient for the population to receive recommended daily servings, fruit and vegetable intake remains inadequate, with a strong seasonal pattern. The horticultural supply in Uzbekistan is characterized by seasonal fluctuations which impact prices and other factors that then affect decisions on consumption. Detailed analysis of such factors was the focus of this study.
