The aim of this study was to compare chemical composition of lemon balm and basil herbage grown in containers under fluorescent lamps (FL) and LED modules (LEDs). There were significant differences in the response of the species for the applied source of light. The content of essential oils was greater in basil herbage under fluorescent lamps, whereas the content of essential oils in lemon balm herbage...
The aim of the experiment was to compare the effect of LED and fluorescent lamps as sources of light on growth and development of sweet basil (Ocimum basilicum L.) and lemon balm (Melissa officinalis L.). The experiment was conducted in growth chambers under controlled conditions. Plant response to the applied light sources was found to be varied. Basil plants produced greater fresh herbage mass as...
Temperature and light are important factors determining growth and development of plants. The difference between day and night temperature (DIF – defined as day temperature minus night temperature) influences plant morphology in a wide range of species. In this study, the effect of photoperiod and DIF on stem elongation and growth of dill plants was investigated. The first experiment included a comparison...
Green moulds of Trichoderma genus cause high losses in oyster mushroom cultivations in many countries. Recently two new species i.e. T. pleurotum and T. pleuroticola have been identified. In the experiment yielding levels of Pleurotus ostreatus growing on substrates infected with Trichoderma isolates were investigated. The following Trichoderma isolates were used: T. pleurotum designated as KWK/17...
The studies were carried out in the years 2006–2007 in an unheated glasshouse. Strawberry mother plants cv. ‘Elsanta’ were grown in polypropylene bags filled with peat-based substrate (3 plants per bag). The bags with plants were placed on gutters in the glasshouse at the height of 165 cm. The distance between the gutters was 120 cm. The experiment was established in a split-block design in 4 replications...
Temperature is a factor which strongly affects the yield and broccoli head quality. Temperature determines the date of head initiation and thus affect the length of vegetation period. An experiment the aim of which was to assess the impact of temperature on the yield and the length of the period from the broccoli head initiation until the beginning and end of harvest as well as the length of the harvest...
Cucumber is one of the most popular vegetables in Poland. This vegetable species is characterised by high requirements in terms of soil temperature and moisture. The utilization of polyethylene mulch in combination with drip irrigation has played a major role in the increases in production of cucumber. The benefits associated with the use of this cultivation method include earlier and higher yields,...
