Effect of long photoperiod on the reproductive and bulbing processes in garlic (Allium sativum L.) genotypes

▶ The effect of ambient day length interruption by 10 or 30 days of long photoperiod was investigated in ten garlic genotypes belonging to four bio-morphological groups. ▶ The competition for resources by the developing bulb and inflorescence sinks differentially determines stalk elongation and flower development in the investigated genotypes. ▶ Flowering in garlic can be promoted by exposure to proper environmental stimuli, during different stages of development.
