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.
![Study on pollen morphology and germination of ‘Pavia’ lilium [Lilium longiflorum] (Narendra Singh Bhandari)](https://www.ishs.org/sites/default/files/styles/thumbnail/public/news-images/narendra_singh_bhandari.jpg?itok=UPbWFHE3 "Study on pollen morphology and germination of ‘Pavia’ lilium [Lilium longiflorum] (Narendra Singh Bhandari)")
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.

Dear members of the ISHS Working Groups Hydroponics and Aquaponics,
As many of you may know, Erik van Os completed his term as the Chair of the ISHS Working Group Hydroponics.
Simultaneously, Tycho Vermeulen informed us that he will not be able to continue serving as the Chair of the ISHS Working Group Aquaponics.
Please let me take this opportunity to thank both of them for serving us in such a productive manner.

Lili Yang is a doctoral student at the Northwest A & F University in China. Her major is plant nutrition and her research is focused mainly on fruit nutrition management, especially of kiwifruit.
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.
