Micropropagation of miniature rose cultivars

A new restructured Hardy-Littlewood's inequality

In this paper, we reconstruct the Hardy-Littlewood’s inequality byusing the method of the weight coefficient and the technic of real analysis includinga best constant factor. An open problem is raised.

Pollen Grain Preservation and Fertility in Valuable Commercial Rose Cultivars

In the cut flower market, traditional breeding is still the best way to achieve new rose cultivars. The geographical delocalization of cultivar constitution (generally made in Europe and North America) and plant cultivation (large areas in Africa and South America) represents a limit point for crossing and selection. Rose breeders often need to overcome geographical distances, resulting in asyn...

Interspecific hybridization among cultivars of hardy Hibiscus species section Muenchhusia.

Rose mallows belong to the Muenchhusia section of the Hibiscus genus. They represent a small group of cold tolerant North American plants and are popular ornamentals mainly because of their abundant, large and colorful flowers. Due to their geographical origin they are well suited for garden use in temperate regions worldwide. The aim of the study was to investigate hybridization barriers in cr...

Root Physiology of Less Fall Dormant, Winter Hardy Alfalfa Selections

in nondormant, nonhardy cultivars when compared with fall dormant plants (Volenec, 1985; Boyce and Volenec, The physiological mechanisms causing fall dormancy (FD)-induced 1992; Castonguay et al., 1995; Cunningham and Volenec, differences in alfalfa (Medicago sativa L.) shoot growth in autumn and winter hardiness are not understood. The objective of this research 1998). Therefore, accumulation ...
