Classification of fruits based on climate adaptability
In this classification, the fruits trees are categorized into three recognized groups.
- Temperate fruit plants are exacting in their climate requirement.
- They are grown only in place where winter is distinctly cold, require as exposure of specific chilling temperature for certain period without which they do not flower.
- These fruit plants are generally deciduous and stand frost. E.g. apple, almond, peach, pear, plum, strawberry, apricot, persimmon, cherimoya, pecan nut, walnut, hassle nut, cherry, pistachios and kiwifruits etc.
- Tropical fruit plants are generally evergreen and are extremely sensitive to cold.
- The plants are generally grown in climatic conditions prevailing in the region between the tropic of cancer (230 (27) N latitude) and the tropic of Capricorn (230 (27) S latitude).
- They do well under lesser fluctuations of diurnal temperature, light and dark periods they require a moist warm climate but are capable of withstanding dry weather in some cases e.g; mango, banana, papaya, sapota, etc.,
- The fruit crops grown under a climatic condition between temperate and the tropical are known as subtropical fruit crops.
- They may be either deciduous or evergreen and are usually able to withstand a low temperature but not the frost.
- They are also quite adoptive to fluctuations of light and dark period during day and night. Some subtropical fruit plants require chilling for flower bud differentiation. Example; grape, citrus, durian, jackfruit, etc.,
