Research Progress on Flowering Period of Hemp

Area of Science:

• Agricultural Science
• Plant Biology
• Genetics

Background:

• Flowering regulation in hemp (Cannabis sativa L.) is crucial for optimizing fiber yield, seed production, and medicinal cannabinoid accumulation.
• Existing research has identified gaps in fundamental understanding of cannabis floral organ development and regulation.
• Effective hemp cultivation and breeding strategies necessitate a comprehensive understanding of flowering control mechanisms.

Purpose of the Study:

• To systematically review current advancements in hemp flowering regulation.
• To examine the morphological, physiological, and genetic underpinnings of flowering in hemp.
• To explore the influence of environmental, nutritional, and stress factors on hemp flowering.

Main Methods:

• Bibliometric analysis to identify research trends and gaps.
• Systematic literature review of flowering regulation mechanisms.
• Examination of genetic loci, molecular pathways, and environmental influences.

Main Results:

• Morphological and physiological aspects of flowering, including phenotype, timing, and differentiation, were analyzed.
• Direct regulatory roles of photoperiod and plant nutrition on flowering were discussed.
• Indirect effects of biotic/abiotic stresses and genetic factors (e.g., Autoflower1, FT pathway) were detailed.

Conclusions:

• Flowering regulation is complex, influenced by genetics, environment, and stress.
• Understanding these factors provides a foundation for precise hemp breeding and cultivation.
• Further research is needed to address identified gaps in basic science for industrial applications.
