I hope to introduce noble interspecific and intraspecific Lilium hybrids and develop cytogenetic assessment techniques to evaluate newly generated hybrids. The objectives of my study were to investigate chromosome behavior and inter-genomic recombination during meiosis of L. longiflorum × L. hansonii progenies.
Zhuping Fan is a candidate for an MS degree at Beijing Forestry University, China. She is studying repeat blooming or remontant flowering of bearded iris (Iris germanica). She is also evaluating Iris through traditional hybridization and molecular breeding methods. Bearded iris appears to have a thick and bushy “beard” on its colorful falls. This flower annually blooms in May in Beijing, China. However, some cultivars bloom twice each year, in May and October. This reblooming enhances the popularity of this flower and adds commercial value to this crop.
Ms. Ziming Ren is a PhD student at Zhejiang University working in ornamental horticulture. The objective of her thesis is to explore the mechanisms regulating the formation and development of bulblets (vegetative propagation) of Lycoris spp. Lycoris is a genus of flowering bulbs of high medicinal and ornamental value belonging to the Amaryllidaceae. This genus consists of about 20 native species that are distributed in Eastern Asia. Lycoris has shade tolerance and a wide range of flower colors, which has recently increased its popularity as flowering ground cover.
Aurelio Scavo is a PhD Student at the Department of Agriculture, Food and Environment (Di3A) of the University of Catania, Italy. His PhD focused on Cynara cardunculus L. allelopathy, with emphasis on sustainable weed control. Allelopathy refers to the ability of some plants to release harmful or beneficial secondary metabolites into the environment. The manipulation of allelopathic mechanisms between plants can produce bioherbicides to promote a chemical-free weed management program. In a first step, the allelopathic effects of leaf aqueous extracts from three C.
Tulipa suaveolens Roth (= T. schrenkii Regel) is an ornamental polycarpic species of the Liliaceae family, and a suspected ancestor of T. ×gesneriana L., the garden tulips. Due to the decline in the size of natural species distribution that resulted from the ploughing of the steppes, the International Union for the Conservation of Nature considers this plant to be on the Red List of threatened plants in Russia, Ukraine, Kazakhstan, and Azerbaijan. By comparison with tulips from other areas of the range, T.

Regulation of fruit size is a major economical factor for numerous horticultural crops. Specifically, in apple (Malus × domestica Borkh.), increases in fruit size will result in increased market value. Many factors play a role in determining final fruit size in apple, some of which have been well studied. Besides being responsible for the attachment of fruit to the tree, the pedicel also provides a connection between the fruit and the source of water and nutrients. Therefore, we hypothesized that the pedicel can be a factor that is involved in the regulation of apple fruit size.
Martin Penzel is a PhD candidate in the Working Group of Precision Horticulture of the Leibniz Institute for Agricultural Engineering and Bioeconomy (ATB), Potsdam, Germany. For his doctoral study he is focusing on precision thinning of apples and the gas exchange patterns of pre-harvest fruit and leaves. His goal is to determine the optimum crop load according to the carbon balance of the trees. The effect of mechanical thinning on fruit drop and final fruit number of ‘Elstar’, ‘Gala’ and ‘Pinova’ apples was investigated in 2011 and 2014.
In banana (Musa L.), somatic embryogenesis (SE) is a high throughput technique for mass propagation of quality planting material, genetic transformation and induced mutations. Through SE, a large number of plantlets can be generated from 1 mL settled cell volume of embryogenic cell suspension (ECS). Although SE is well reported in selected banana cultivars, most of the commercial cultivars are recalcitrant to SE. Knowledge of the genes responsible for SE is important to induce SE in recalcitrant cultivars.
Fares Belhassine is a PhD candidate studying alternate bearing of apple trees (Malus × domestica Borkh.), at the French National Institute for Agricultural Research (INRA), in the Architecture and Functioning of Fruit Tree (AFEF) team, Montpellier, France. Fruit trees are prone to alternate bearing and the inhibition of floral induction (FI) under high crop load conditions.
Agriculture has evolved tremendously to increase productivity and quality in the past decades. It was often achieved by plant breeding and at the cost of an increasing dependence on external inputs, i.e., water, fertilizers and pesticides. Apple orchards are no exception. Society is now questioning the means used because of the generated environmental pollution and health issues. Different solutions have been considered to reduce this dependence including redesigning agrosystems to rely on ecosystem-based services.

Ms. Diana Valle is currently a PhD student at the Instituto Nacional de Investigación Agropecuaria (INIA Las Brujas) in Uruguay. For her master’s studies she focused on finding alternative strategies to the chemical control of Cacopsylla bidens, one of the main pests in pear orchards. Following that work in her PhD, she is mapping the trophic networks that involve C. bidens as a prey, because the information is scarce on which of the generalist predators is effectively feeding on C. bidens.
Ms. Violeta Lindo García is a PhD student at the Institute for Food and Agricultural Research and Technology (IRTA) in Lleida (Spain) working in the field of postharvest physiology. The main objective of her thesis is to study the biochemical and physiological basis of superficial scald in different pear cultivars as well as to elucidate some key aspects of pear ripening. Superficial scald is a physiological disorder affecting the peel of both apples and pears after cold storage and leading to important economic losses.
