Summary |
Stress can seriously limit vegetable production in karst area. Vegetables are produced on 130,000 ha in Croatia, with more than half in karst regions. Abiotic (water, temperature, light, wind, nutrients, salinity) and biotic stresses (diseases, insects and weeds), either single or in combination, can reduce yields up to 80%. Improved understanding of plant defense mechanisms would provide means to develop crop strategies aimed at alleviating these uncontrollable stressors. Alternatively, control stressors during critical period of growth and development could enhance plant stress tolerance by increasing signal compounds that may affect product quality and/or yield. The specific goals of this projects are: a) determine the effects of limited irrigation on water and nutrients uptake, yield, quality, and sensitivity to biotic stressors in hydroponic production; b) determine the effects of substrate salinity and/or limited irrigation on morphological, physiological and biochemical plant responses, yield and quality of vegetable crops; c) evaluate how exogenous growth regulators and antitranspirants modulate growth and physiological responses under abiotic stressors; d) determine the efficacy of non-toxic methods in crop protection against aerial pests and soil and root pests; and e) investigate host-virus-vector interactions and develop an inventory of virus-vectors (Aphidoidea and Aleyrodidae) for vegetable species. From this project we expect to develop acceptable procedures and approaches, both ecologically and toxicollogically, for increased productivity and quality of vegetable crops in karst region. These methods are even more important as we approach the transition of conventional production to integrated farming, as well as to preserve sensitive karst ecosystems. |
