Flower color is the main character throughout the plant kingdom. Though substantial information exists regarding the structural and regulatory genes involved in anthocyanin and flavonol biosynthesis, little is known that what make a diverse white vs. red color flower in natural species. Here, the contents of pigments in seven species from varied phylogenetic location in plants with red and whit...

In an interior environment, the display life of miniature potted roses (Rosa hybrida L.) `Bronze' was 7 days, while that of `Vanilla' was 23 days. Although there was a substantial difference in ethylene production between flowers from two cultivars, there was no difference in binding site activity (kd ˆ 0.14 nl lÿ1). Pre-treatment with the ethylene action inhibitor 1-methylcyclopropene (1-MCP) ...

The effects of various growing substrates, combinations of soil, silt, sand, press mud (PM) and rice hulls (RH) on plant growth, yield and quality of rose (Rosa hybrida L.) cvs. Kardinal, Anjlique and Gold Medal, were studied to standardize substrates for cut rose production and develop better management and quality production protocol. Plant height, number of leaves branch, leaf area, number o...

Abstract Rose is an ornamental plant, which constitutes one of the leading cut flowers in world. The vase life Rosa hybrida L. truly short. We examined effect various temperatures and different time duration factors on postharvest longevity, some other physic-biochemical characteristics antioxidants activity. Fresh were treated by water with (23º, 42º, 47º, 52°C) (5, 10, 15, 20 min). Maximum (7...
