Researchers examine water retainer’s effects on tomato seedlings
As a result of climate change, drought and the unequal distribution of rainfall is a worldwide problem. Drought stress on plants affects not only the yield but also the amount and ratio of bioactive components in tomato fruit. The present work aimed to investigate the effect of a new soil biodegradable water-retention agent (Water and Soil’s Water Retainer, Water and Soil Ltd., Budapest, Hungary) containing natural ingredients during the seedling period and under different irrigation conditions on the product volume, dry matter content and on some characteristic secondary metabolites in tomato fruits.
The study was conducted to screen four different irrigation and soil treatment combination treatments for production and quality characteristics (polyphenols, tocopherols, carotenoids, vitamin C) to check the effect of seedling-stage stress on tomato yield and bioactive components. Significant differences were found between the treatment and the cultivation seasons for the phytochemical content of fruits.
