Key Points

The study aims to understand how light conditions and hormones regulate carbon metabolism and flowering in black pepper.
Utilized transcriptomics to analyze gene regulation during inflorescence development.
Applied 30% shading and 60 mg/L gibberellic acid to evaluate effects on flowering.
Investigated the role of light in mediating carbon allocation pathways.
30% shading significantly enhanced inflorescence development, promoting off-season bud formation.
Application of 60 mg/L gibberellic acid further increased the rate of flowering.
Light regulates flowering processes through hormone-mediated pathways influencing carbon allocation.

Implication

Demonstrates enhanced inflorescence development in black pepper via shading and hormone signaling, suggesting non-chemical flowering control.

Abstract

• Transcriptomics reveals dynamic regulation during pepper inflorescence development. • 30% shading and/or 60 mg/L gibberellic acid enhances inflorescence development. • Shading alone enables non-chemical control of off-season bud formation. • Light regulates flowering via hormone-mediated carbon allocation pathways. • Sucrose synthesis and transport are key processes in light-regulated flowering.
