Adaptation of wheat to a tropical environment
type: CreativeWork
description: Wheat consumption in Indonesia is continuously increasing. Indonesia imports considerable amounts of wheat for domestic consumption and processing and this has increased with economic development. Therefore to lower the high import of wheat grains, Indonesia should have domestic production. Even though Indonesia straddles the equator, the high altitudes in many parts of Indonesia means that wheat could potentially be grown during the dry season as it is more drought tolerant than rice. However, improved adaptation of wheat to tropical environments is needed to achieve this goal. Lombok Island (8.5°S 116°E) is suggested to be one of the potential areas of wheat growing. The average maximum temperature at the capital city, Mataram (low altitude) is 30-32°C during day time and minimum at 20-23°C at night but this is moderated by elevation in the centre of the island. The lowest temperature during the year is between June and August which also is the dry season. Lombok’s current farming system consists of two rice plantings during the rainy season and a non-rice planting during the dry season. May to September is proposed to be the wheat growing period on Lombok to have the plant flowering during the time of lowest temperatures and coincidently with no or limited rainfall during grain development to avoid grain sprouting in the field before harvested. In order to investigate the adaptation of wheat on Lombok Island Indonesia, a series of growth chamber and field experiments was conducted. The initial controlled environment experiments at Adelaide University that examined patterns of apical development and seedling growth were done at a continuously high temperature (32/23°C) day/night to imitate temperatures at lowland sites of Lombok Island while in later experiments in which development, growth and yield were studied, the temperature treatments were expanded to 3 temperature regime, 32/23°C, 28/20°C to imitate lowland and highland temperatures of Lombok Island and 25/…
