Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 1
Abstract
Allium hirtifolium Boiss. known as Persian shallot, is a spice used as a traditional medicine in Iran and, Mediterranean region. In this study phonological stages of Persian shallot was detected based on growth degree days (GDD). The results showed that persian shallot cultivated in growth period of about 150 days in Mashhad condition. Early stage of growth at 8 degrees day started in the leaves of vegetative and flowering stages of shoot growth to continue. Maximum frequency between 494 to 693 degrees in open flowers - day growth occurred between 10 and 20 April of the calendar and the third month of the shoot . Opened the scoring in the third month of shoot emergence was observed. The highest average frequency of seeding 1236.5 GDD to 1447, coinciding with the June 18 and 26 , the temperature at this time was almost up.
