HORTICULTURE ..................?

                                    HORTICULTURE........

                                  Horticulture is divided into the cultivation of plants for      food (pomology and olericulture) and plants for ornament  (floriculture and landscape  horticulture).Pomology deals with furit and nut crops. Olericulture deals with herbaceous plants for the kitchen, including, for example, carrots (edible root), asparagus(edible stem), lettuce (edible leaf), cauliflower  (edible flower buds),tamatoes (edible fruit)and peas  (edible seed).Flori culture,deals with the production of flowers and ornamental plants, generally, cut flowers, pot plants, and greenery. Landscape horticulture is a broad category that includes plants for the landscape, including lawn turf but particularly nursery crops such as shrubs, trees   and vines. that is called horticulture ..........


SPECIALIZATION OF HORTICULTURE ....

The specialization of the horticulturist and the success of the crop are influenced by many factors. Among these are climate, terrain, and other regional variations...........

       

Horticultural Regions

Temprature Zone ........

Temperate zones for horticulture cannot be defined exactly by lines of latitude or longitude but are usually regarded as including those areas where frost in winter occurs, even though rarely. Thus, most parts of Europe north america and northern Asia are included, though some parts of the United States, such as southern Florida, are considered subtropical. A few parts of the north coast of the Mediterranean and the Mediterranean islands are also subtropical. In the Southern Hemisphere, practically all of New zealand  a few parts of Australia, and the southern part of South America  have temperate climates. For horticultural purposes altitude is also a factor; the lower slopes of great mountain ranges, such as the Himalayas and the ands, are included. Thus, the temperate zones are very wide and the range of plants that can be grown in them is enormous, probably greater than in either the subtropical or tropical zones. In the temperate zones are the great coniferous and deciduous forests: pine, spruce , fir, most of the cypresses the deciduous oaks  (but excluding many of the evergreen ones), ash brich and linden................
