As a horticultural expert with a deep understanding of fruit tree biology and pollination mechanisms, I can provide you with an in-depth answer to your question about lychee trees and their pollination habits.
Step 1: English Answer
Lychee trees, scientifically known as *Litchi chinensis*, are tropical and subtropical fruit trees that are valued for their sweet and aromatic fruit. When it comes to pollination, lychee trees are often considered to be self-pollinating. This means that they have the ability to pollinate themselves without the need for another tree of the same species. The flowers of lychee trees are typically perfect or bisexual, containing both male (stamens) and female (pistil) reproductive organs within the same flower.
However, while lychee trees can self-pollinate, it is important to understand that this does not mean they are entirely independent of external factors for successful fruit production. There are several conditions that can affect the pollination and fruit set of lychee trees:
1. Temperature: Lychee trees are sensitive to temperature fluctuations. As mentioned in the reference, they require a period of cool night temperatures (below 20°C or 68°F) for about a week before flowering to stimulate the growth of flowers and fruit. This cool period is crucial for the tree to transition from the vegetative phase to the reproductive phase.
2. Cross-Pollination: Although lychee trees can self-pollinate, cross-pollination can still occur, especially when there are other lychee trees nearby. Cross-pollination can lead to greater genetic diversity, which can be beneficial for the overall health and vigor of the trees and the quality of the fruit.
3. Pollinators: While self-pollination can occur, the presence of pollinators such as bees, butterflies, and other insects can significantly increase the chances of successful pollination and fruit set. These pollinators can transfer pollen from one flower to another, both within the same tree and between different trees.
4. Cultural Practices: Proper care and management of lychee trees, including pruning, fertilization, and irrigation, can also impact their ability to produce fruit. Good agricultural practices can enhance the overall health of the tree, which in turn can improve its reproductive success.
5. Variety: Some varieties of lychee may be more prone to self-pollination than others. Certain cultivars may have flowers that are more accessible to pollinators or have characteristics that make them more effective at self-pollination.
6. Environmental Stress: Environmental factors such as drought, excessive heat, or poor soil conditions can stress the tree and affect its ability to produce fruit, even if it is capable of self-pollination.
In conclusion, while lychee trees are capable of self-pollination, the process is not foolproof and can be influenced by a variety of factors. Growers should be aware of these factors and take steps to ensure that their lychee trees have the best possible conditions for successful pollination and fruit production.

Lychees are self-pollinating, producing both male and female flowers on the same panicle, so only one tree is needed to get fruit. To become productive trees however, they need a week of cool night temperatures (below 20--C) before flowering.Mar 28, 2009
