Preharvest conditions, including photoperiod and irrigation regime, affect the keeping quality of long stem roses (Rosa x hybrida). Rose plants cultivar ‘Charming Black’ were subjected to four different treatments investigate how nocturnal supplemental lighting regimes influence post-harvest performance. Vase life, ornamental quality, water balance, petal color, vacuolar pH, soluble sugar conte...
Nowadays, various training systems are utilized to grow greenhouse roses. Some of the training systems permit high canopy light penetration and hence increase canopy photosynthesis rate. The aim of this investigation was to evaluate the response of arching and traditional training systems to shading (0 (no shading/control), 25, 50 and 65%) and their effects on marketing quality of cut roses (...
Sugar has only recently been identified as a key player in triggering bud outgrowth, while hormonal control of bud outgrowth is already well established. To get a better understanding of sugar control, the present study investigated how sugar availability modulates the hormonal network during bud outgrowth in Rosa hybrida. Other plant models, for which mutants are available, were used when nece...
The subject of this study was to get more information about the root zone, mainly the gas composition in growing media, which is used in hydroponic systems. Besides the plant growth parameters of roses, yield and nutrient uptake, the results of the gas concentrations in the root zone are presented. Gas sampling at 2 or 3 heights from root zone did function well, results ranged from 530 ppm to 1...
