Effects of seed priming with salicylic acid on cuticular wax deposition in sweet sorghum under drought stress.

ABSTRACT:

Background

Seed priming is an affordable and effective method to enhance crop drought tolerance by improving seed germination and seedling vigor. However, whether seed priming alters cuticle formation, which could contribute to drought resistance in seedlings, remains unclear.

Materials and methods

In this study, sweet sorghum seeds belonging to three varieties were primed with salicylic acid (SA) and the seedlings were exposed to drought stress. The seeds were primed with SA with concentrations of 50, 100, 150, 200, 250 mg L^-1. For drought treatment (35% field capacity, 80% of field capacity as the normal condition), both SA-primed and non-primed seeds were planted in a soil mixture.

Results

Under drought conditions, SA priming at 150 mg L^-1 sig
