STRATEGIES FOR CROP PRODUCTIVITY, STABILITY AND QUALITY
In the last years more attention has been posed on crop productivity and quality. The increasing attention on food chains has stressed the opportunity to revaluate the concept of food security and safety, that are no more a per se value but a concept strongly related to the market and consumer’s needs. Thence, crop productivity, stability and quality is now declined in several different ways depending on the output requested. Crop practices in the field or handling and processing practices during post-harvest are then involved and applied following different strategies. Our main goal is to single out food or feed chain needs and to translate knowledge into opportunities for farmers, processors and all players through an updated scientific approach.
Sub-theme I. Crop Science I: Mycotoxin control in cereals
The research group has been involved since the year 2000 in projects concerning the mycotoxin occurrence and prevention in cereals. Since the good agricultural practice (GAP) requires an integrated approach that addresses all the possible risk factors in order to prevent mycotoxin contamination, the interactions between the crop techniques and the effect of field programmes have been studied in order to minimize the incidence of mycotoxins and to reduce their contamination throughout the feed and food chain. The fate of mycotoxins in the main cereal chain transformation was also investigated, in particular the decontamination during the milling process, and the effect of several post-harvest treatments to reduce the contamination in cereal grains, derived-product and by-products.
The research group skills are related to the study of field management tools able to reduce mycotoxin contamination in maize, common wheat, durum wheat and barley, following an integrated approach which considers the whole cropping system. The aim of the research activity is focused to identify and verify at a pre- and post-harvest levels technical, management and organizational solutions that could be effective to minimize mycotoxin contamination risk in the cereal food and feed chains.
Sub-theme II. Crop Science II: Productivity and technological quality of cereal
The research team aims to investigate the relationship between the crop practices and the productive, technological and nutritional characteristics of cereals for food, feed and industrial applications.
The team is involved in the identification of innovative Good Agricultural Practices and Good Management Practices in order to improve the productivity and the quality of cereals within the whole chain, taking into account the fundamental interaction with the pedo-climatic conditions. The data obtained are used for the Development of Crop Management Systems for specific productive orientations, considering with particular attention the innovative and emerging supply chains for cereals.
As far as the qualitative parameters is concerned, the most recent activities included:
- the effect of fertilization and disease prevention on rheological and bread-making properties of common wheat intended for different end-use (for biscuits, bread-making or improver wheat) and on pasta-making quality of durum wheat;
- the effect of varietal choice and of crop management practices on maize kernel hardness within the dry-milling and semi-wet milling chain;
- the relationship between the main cereal pests and the implication on grain quality and safety;
- the production of innovative cereal ingredients with high added value in the production of new bakery products characterized by specific health benefits.
Sub-theme III. Horticultural Science
The group has focused its attention throughout the years on the whole food chain, from the agricultural chain up to the final food production. Several research projects have been undertaken throughout the years working on physiological and technological aspects of fresh-cut products. Specifically, the research team has investigated the effects of cultivation practices on the quality of the produce at harvest, on the postharvest handling, processing and packaging. The intrinsic quality of fruit and leafy vegetables have been studied throughout the postharvest shelf-life, focusing on respiratory processes, quality decay of the product, temperature and light abuse during shelf-life, temperature abuse at harvesting, microbial spoilage and safety aspects during production and processing. Some research activities have been conducted in collaboration with foreign research institutes. The group has also a long experience on Medicinal and Aromatic Plants (MAP) and their use in the agrifood sector. Some projects have dealt and are under going on the plant natural bioactive compounds to be used in the agrifood sector as natural preservative. The systems approach adopted implies the pursuing the crop productivity stability by enhancing growing systems with technological innovations. Soilless culture systems are developed and investigated to produce constant and consistent yield, of prime quality both for the fresh market and for the postharvest technology processes.
Sub-theme IV. Insect vectors of plant pathogens
Insect-transmitted diseases of plants, namely of grapevine and horticultural crops, are of major importance in the Piemonte Region. They have a dramatic impact on crop yield and crop protection strategies with important consequences on the whole food chain and on the economic and social structure of some agricultural sections. The research team investigates biology, ethology and ecology of leafhopper, planthopper, psyllid and mealybug vectors of grapevine and fruit tree phytoplasmas and of viruses infecting horticultural crops and grapevine. The epidemiology of these arthropod-borne diseases is also a focus of the research. Specifically the research group has studied:
- vector life cycle and population dynamics, seasonal and daily movement, and spatial dispersal
- phytoplasma fate and multiplication in leafhoppers and psyllids, gene expression in healthy and phytoplasma-infected leafhoppers, molecular determinants of phytoplasma transmission specificity (in vitro and in vivo interactions of phytoplasma and insect proteins)
- interactions between insect vectors and their microbial symbionts
- thrips-tospovirus relationships in the Frankliniella occidentalis-Tomato spotted wilt virus (TSWV) association
- mealybug-viruses relationships in the Planococcus/Heliococcus-grapevine leaf roll viruses association
- molecular markers for the identification of vector species, biotypes and haplotypes.
