The Modification of Substrate in the Soilless Cultivation of Raspberries (Rubus Idaeus L.) as a Factor Stimulating the Biosynthesis of Selected Bioactive Compounds in Fruits

Original language description

Raspberry has been cultivated in many regions of the world for several centuries. It has a number of varieties with different cultivation requirements and fruiting periods. Depending on the variety, the produced fruits also differ in terms of the content of vitamins, bioactive compounds, and their shelf life. Most of the varieties are intended for field cultivation, and their fruits are suitable only for processing. Dessert raspberries are grown mainly under cover in a soilless system using fertigation. Various types of substrates are used for raspberry cultivation including peat substrate, perlite, coke, mineral wool, and coconut fibre. However, due to the susceptibility to recirculation, more and more natural substrates are being used including mainly coconut fibre. It is a cheaper alternative to mineral wool, also used in soilless cultivation. Coconut fibre has an excellent air-to-water ratio, which makes it difficult to overwater in this type of cultivation. In addition, the fibre has a high cationic exchange, which means that unused minerals can be stored and used as needed at the right time. It is colonised by fungi of the genus Trichoderma, which have a protective function. Its mycelium covers the plant roots, thus protecting them against dangerous pathogens and stimulating root growth. Coconut fibres are made of cellulose with limited sorption properties and increased susceptibility to degradation. These features require modification of coconut fibre substrates by adding various mineral and organic components that extend the life of these substrates and improve their physical properties. Raspberry fruits are a very good source of dietary fibre, minerals (especially manganese), vitamin C, and bioactive ingredients, mainly polyphenols. In addition, these fruits are characterised by strong antioxidant properties, which are useful for producing anti-inflammatory preparations. The composition and content of bioactive compounds in raspberry fruits can be modified by fertilisation (using different nutrients for fertigation) or by changing the composition of the substrate. The aim of the study was to modify the substrate in the soilless cultivation of raspberries to stimulate the biosynthesis of selected bioactive compounds in the fruit. The scope of the work included the preparation of substrates with various mineral and organic additives, which were tested in the greenhouse cultivation of raspberries. The fruit produced was analysed for the selected bioactive compounds (polyphenol content and profile, vitamin C content, antioxidant potential) and selected stress markers were measured.
