Developmental Stages of Single-stem Cut Rose Production

Predicting Cut Rose Stages of Development and Leaf Color Variations by Means of Image Analysis Technique

The monitor and prediction of crop developmental stages, particularly harvest time, play an important role in planning greenhouse cropping programs and timetables by cut rose producers. There have been many scientific reports on the application of image analysis technology in estimating greenhouse crop growth stages. In the present research, we studied leaf color variations over time by taking ...

Microcalorimetry: a Novel Approach to Decision Making in Cut Rose Production

Since its innovative use by Lavoisier at the end of the eighteen-century, calorimetry has been one of the most important foundations of modern science. However, only recently, with the advent of modern and accurate sensors, has it to play a central role in the life sciences. The combination of calorimetric and respirometric studies resulted in a thermodynamic model that represents the rate of s...

Impact of Exogenous Spermine Application on the Vase Life of Cut Rose Flowers ‘Dolce Vita’

Senescence is an integral part of the normal developmental cycle of plants and can be traced in cell, tissue and organ level. This work was focused on the efficiency of post-harvest treatment with the free polyamine spermine (Spm) to extend the vase life of cut rose flowers as an anti-senescence compound. Spm treatment was applied at the rates of 0, 1, 2 and 4 mM. Some morphological, biochemica...

Developmental Vitamin D Availability Impacts Hematopoietic Stem Cell Production

Vitamin D insufficiency is a worldwide epidemic affecting billions of individuals, including pregnant women and children. Despite its high incidence, the impact of active vitamin D3 (1,25(OH)D3) on embryonic development beyond osteo-regulation remains largely undefined. Here, we demonstrate that 1,25(OH)D3 availability modulates zebrafish hematopoietic stem and progenitor cell (HSPC) production...
