Effects on Wheat Seed Germination and Seedling Growth under Salt Treatment: Endophytic Fungi Fermentation Broth

doi:10.11924/j.issn.1000-6850.casb2023-0218

Abstract

Abstract:

The aim was to clarify the effects of the interaction between endophytic fungal fermentation broth and salt stress on wheat seed germination and seedling growth. Using ‘Huaimai 44’ as the material, indoor germination experiments and greenhouse pot experiments were conducted to collect data on wheat seed germination and seedling growth. The results showed that low salt concentration promoted the germination and seedling growth of wheat seeds, while high salt concentration inhibited their germination and growth. With the increase of salt stress concentration, the germination rate, germination potential and germination index as well as radical length, and embryo length of wheat seeds showed a trend of first increasing and then decreasing, while the fresh and dry weight and aboveground plant height and fresh weight of seedlings showed a linear downward trend. Spraying 10% endophytic fungal fermentation broth had a significant promoting effect on the germination rate, germination potential, dry and fresh weight, radicle length, and aboveground plant height of wheat seeds. Endophytic fungal fermentation broth can promote the germination of wheat seeds and seedling growth under salt stress conditions, thereby improving wheat salt tolerance.

Key words: wheat, endophytic fungus fermentation broth, salt stress, seed germination, seedling growth, facilitation
