Developmental Responses of Garlic to Temperature and Photoperiod

Bulb initiation and maturity of four Chilean clones of garlic (Allium sativum L.) were studied in controlled and field conditions in order to assess temperature and photoperiod requirements of selected clones. The effect of cold storage temperature prior to planting and photoperiod on bulb initiatio...

Bulb initiation and maturity of four Chilean clones of garlic (Allium sativum L.) were studied in controlled and field conditions in order to assess temperature and photoperiod requirements of selected clones. The effect of cold storage temperature prior to planting and photoperiod on bulb initiation was assessed in two clones of garlic. In one experiment bulbs were stored at 4, 7, 10, 13 and 16°C for 20, 40 or 60 days, and planted in pots in a heated greenhouse with a 14 h photoperiod.

Percentage of bulbing increased and the number of days from emergence to bulb initiation decreased, as storage temperature decreased and duration of storage increased.
