WP 3. Pre-breeding Cucurbita for tolerance to abiotic stress, by using metabolic stress markers

Identifying the most relevant metabolic stress marker(s) that can be used at early stages of plant development to pre-breed for tolerance to abiotic stress

3.1. Determining the content of the proposed metabolic stress markers in the leaves of young Cucurbita moschata, maxima, and pepo plants
3.2. Determining the above parameters in stressed and non-stressed plants grown in the open field, at generative phase of development and interpreting the results
