Application of zinc microparticles in hydroponic cultivation of strawberries (Fagaria x ananasa)

Hydroponic cultivation makes it possible to harvest strawberries (Fragaria x ananasa) at a time when this was not possible before. This breeding achieves somewhat earlier fruiting, a longer harvesting period, higher yield and fruit quality. To achieve this, with appropriate microclimatic conditions, an adequate substrate, regular fertigation and protection against disease and pests are required. Zinc is one of the most important trace elements in strawberry flowers and fruits. Zinc deficiency affects the decreased growth of stamens and the growth of pollen tubes, which can result in deformation of the fruit. Zinc microparticles are one way to improve the nutritional properties (total polyphenols, flavonoids, anthocyanins and antioxidant activity) of strawberry fruit. In this study, the experiment was set up according to the split-plot method in three repetitions. The treatment was performed on two different strawberry varieties: Albion and San Andreas. The strawberries were treated with microparticles containing zinc as the active substance and microparticles containing zinc and an additional layer of chitosan. The results showed a positive effect of microparticles on strawberries.
