Abstract
Litchi (Litchi chinensis Sonn.) and longan (Dimocarpus longan Lour.) are Sapindaceae making significant contributions to the lives of millions of people in tropical and subtropical regions.
These tree crops have to experience environmental triggers or stresses such as chilling, drought or oxidative stress to induce flowering.
Chilling induces flowering in litchi and longan.
Potassium chlorate treatment, which results in oxidative stress, is efficient in flower induction in longan.
Other studies have shown that reactive oxygen species (ROS) accumulate as a result of oxidative stress arising from environmental stresses.
Likewise, nitric oxide (NO), a reactive nitrogen species accumulates when plants are subject to environmental stresses.
ROS and NO are key signaling molecules involved in plant responses to stresses.
The paper summarizes the studies of environmental triggers or stress on flowering in litchi and longan.
The possible role of ROS and NO as triggers or stress signals in flowering of litchi and longan and how these signals are produced is discussed.
Moreover, the effect of the signals on flowering including their relation to carbohydrates, phytohormones and gene expression are summarized.
