The amount and composition of phytohormones, sugars, and some other leaf characteristics depending on a crop load were evaluated in apple (Malus domestica Borkh. cv. Ligol grafted on P 60 rootstock) trees in order to prevent biennial bearing. The crop load was adjusted to 12 (control, unthinned), 8, 4, and 0 (non-fruiting) inflorescences (or fruits) per cm2 of trunk cross-sectional area (TCSA). Inflorescences...
In this study, we sought to find and employ positive effects of UV-A irradiation on cultivation and quality of microgreens. Therefore, the goal of our study was to investigate the influence of 366, 390, and 402 nm UV-A LED wavelengths, supplemental for the basal solid-state lighting system at two UV-A irradiation levels on the growth and phytochemical contents of different microgreen plants. Depending...
In greenhouses, artificial lighting is applied in winter and early spring as sup-plementary light source to increase photosynthesis and plant growth. The objective of this study was to evaluate the cultivation of sweet pepper transplants under LED lamps that were developed to supplement HPS lamps used in greenhouses. The experiments were carried out in the greenhouses at the Lithuanian Research Centre...
The cost and yield are two the most important criteria in agriculture by which optimization of environmental factors are needed to carry out. In the present study, we investigated the efficient lighting spectrum and elevated CO2 concentration for cultivating healthier plants more rapidly. One of the aims of our study is to optimize LEDs light spectrum for healthier vegetable production in greenhouses...
