Floriculture is a discipline of horticulture concerned with the cultivation of flowers and ornamental plants for floral industry and for garden. In Floriculture the accurate forecasting of the yield and their estimation from the raw data are playing the important role in the planning of various aspects of Horticulture production. In most cases, such counting procedure is performed manually, whi...

background and objectives: drought is one of the most important factor limiting plant growth around the world and the most common environmental stress which is limited produce approximately 25% of the world's land. production of secondary metabolites in medicinal plants changes by environmental condition and also water stress is effective factor in growth and synthesis natural compounds in...

Leaves originate from the shoot apical meristem, a small mound of undifferentiated tissue at the tip of the stem. Leaf formation begins with the selection of a group of founder cells in the so-called peripheral zone at the flank of the meristem, followed by the initiation of local growth and finally morphogenesis of the resulting bulge into a differentiated leaf. Whereas the mechanisms controll...

in order to determinate appropriate stability parameters, six statistics were studied for flower yield stability of 35 rosa damascena landraces in 8 locations over two years (2007-8) in iran, using a randomized complete blocks design with 3 replications. a positive correlation between environmental variance (s2) and flower yield suggested that only low yield landraces develop a similar phenotyp...

BACKGROUND Understanding the mode and mechanisms of the evolution of the angiosperm flower is a long-standing and central problem of evolutionary biology and botany. It has essentially remained unsolved, however. In contrast, considerable progress has recently been made in our understanding of the genetic basis of flower development in some extant model species. The knowledge that accumulated t...

Environmental factors affecting flower development may limit the yields of fruiting crops worldwide. In temperate regions, chilling temperatures during flower development can compromise fruit production, but their negative effects vary depending on the differing susceptibilities of each developmental stage. The cultivated strawberry (Fragaria× ananassa Duch.) is widely grown worldwide but finan...
