Evaluating the combined effects of light and water availability on the early growth and physiology of Tamarindus indica: Implications for restoration

Premise: The tamarind tree (Tamarindus indica L.), is a species of significant cultural, economic, and ecological value, with a pantropical distribution. However, the tamarind is experiencing a decline in wild populations in its native range, but the reasons for its decline remain unknown.
Methods: We examined the critical early life history stages for tamarind establishment to understand how varying levels of light and water availability and watering frequency affect its regeneration. Through three greenhouse experiments we assessed the impact of these resources on the germination, survival, growth, and physiological responses or tamarind seedlings and saplings.
Results: Water availability was critical for seed germination, but not light levels or pre-germination treatments. Light was the primary limiting factor for seedling growth. Tamarinds in high light availability grew taller, had a higher biomass and a larger diameter, but this effect was modulated by water availability, indicati..., This data was collected from experiments conducted in a greenhouse at the University of Minnesota. The available data is the data gathered during the course of the experiments. Three different experiments were carried. The first one was a seed germination experiment. For the second one, we employed tamarind seedlings and for the third one tamarind saplings. The data was recorded in excel files and has not been transformed. , , # Evaluating the combined effects of light and water availability on the early growth and physiology of Tamarindus indica: Implications for restoration

## Description of the data and file structure

### Tamarindus indica seed germination and early growth

This dataset contains three files with the results of three greenhouse experiments designed to assess the impact of two critical resources, light and water, on the germination, survival, growth, and physiological responses of tamarind seedlings and saplings.

1. The file \"Tamarind germination\" contains the data of the first experiment designed to evaluate the germination responses of tamarind seeds under varying light and water conditions. We sowed 300 seeds in germination trays filled with Sungro Professional Growing Mix, positioning them approximately 5 mm below the surface. The seeds, with an average mass of 1.05 g, were distributed across three lig...
