Abstract
The highest content of chlorophyll a was in mints irrigated with nano water and fertilisers (108.39 mg lOOg"1). Plants irrigated with drinking water and fertilisers were the least yellow (b*) (18.94 NBS units), while the ones irrigated with nano water were the brightest (44.65 NBS units). Fertilisation had positive influence on the content of dry matter, crude ash as well as chlorophylls. Nano water increased chlorophyll a content and brightness in mints.
Mentha plants are one of the most used plants in the world due to their medical properties. Water plays the most important role in growth and evolution of plants, as plants' stomata loftness and also photosynthesis intensity depend on water content regime. High level of oxygen has positive influence on plants' root system. The research was earned out at Aleksandras Stulginskis University, Faculty of Agronomy, Institute of Agriculture and Food Science in 2017-2018. The research aim was to determine the influence of nano water (saturated with oxygen) on chemical composition and colour parameters of Mentha spicata 'Moroccan'. The study was performed by applying a pot experiment in completely randomised block design with tree replicates of each variant in the greenhouse, during the spring period of 2017. Mints were planted in Micherlich pots with pH 5.5-6.5 peat substrate. The plants were grown under 22/18 °C (day/night) temperature, with 8h photoperiods. Mints were irrigated with nano water and drinking water every 4 days, and fertilised 3-times every 2 weeks with nano water + complex NPK fertilisers (6-3.5-6) and drinking water + complex NPK fertilisers (6-3.5-6) of concentration 10 ml l"1. Mints were harvested 10 weeks after the plantation. Standard methods were used to determine the quality of water, the amount of dry matter, ash, chlorophylls and colour parameters of M. spicata 'Moroccan' dried at 30 °C temperature. The results showed that the usage of water with different properties had no significant effect on dry matter and the crude ash content in the mint leaves. Dry matter and crude ash content were the highest in mints treated with fertilisers despite the used water.
