Rambutan bearing fruits depending on droughts

Rambutan is a fruit that can be planted in an equatorial country. The unique thing about rambutan in Malaysia is that it bears fruit after every period of drought. If Malaysia experiences only a single period of drought, the rambutan will bear fruit once, and if there are years when Malaysia experiences two periods of drought, the rambutan will bear fruit twice this year. Rambutan in Malaysia is intended for the local market and is also exported to Singapore, the EU, the USA, and many other countries.
