Effects of Pollen Germination and Pollen Tube Growth under Different Temperature Stresses in Mango (<i>Mangifera indica</i> L.) by Metabolome.

ABSTRACT:

Background

The dramatic temperature fluctuations spurred by global warming and the accompanying extreme weather events inhibit mango growth and threaten mango productivity. Particularly, mango flowering is highly sensitive to temperature changes. The mango fruit setting rate was significantly positively correlated with pollen activity, and pollen activity was regulated by different metabolites.

Methods

In this study, the in vitro pollen of two mango varieties ('Renong No.1' and 'Jinhuang'), in which sensitivity to temperature differed significantly, were subjected to different temperature stresses (15 °C, 25 °C and 35 °C), and their metabolomics were analyzed.

Results

The present results showed that 775 differential metabolites were screened by liquid chromatography-m
