TASK 4

Why are certain plants grown commercially in some countries but not in others?

Most traditional flower crops grown commercially today are the result of many years of intensive selection and breeding. For example, carnations have been grown for over 2000 years and have been improved by breeders since the 16th century, making the carnations that a florist uses today very different from the original wild parents. This means that a wide range of flower colours and forms is available to cater for the fashion trend of the moment.
In sharp contrast, relatively few some countries native plants have been the focus of rigorous improvement programs, and any selection programs have commenced only recently. Ironically, this provides with a competitive advantage. Many country natives are basically still wild plants, grown from seed. Some species, for example kangaroo,elephant, rat paw and wax flower, have already become world crops and offer the market a great diversity of form and colour.
Another perceived difference between people in other country native and traditional cut-flower crops is the length of the flowering season. Under outdoor conditions, many crops like roses and carnations produce flowers throughout most of the year. Other crops like chrysanthemums have a short flowering season, but commercial growers can produce flowers for most of the year by choosing early and late flowering varieties and by artificially controlling the daylength under which they are grown.
Many species mostly flower in spring and have a relatively short flowering season. Little is known about what triggers flowering in these plants, making the manipulation of crops, so that they flower on demand, a long way off. Undoubtedly there are benefits of applying production technology, developed for traditional crops, to native flower growing.
Many native flowers and foliages now being grown commercially were initially mostly bush-picked to first establish market acceptance. Today, most are grown in beds or rows in commercial plantations along the coastal strip where there are suitable growing conditions and good transport links to major domestic and export markets.
