Commercial Floriculture

Culture- Climate

• Gladioli require full exposure to sunlight for better crop, otherwise blasting may occur or plants may remain blind.
• The long day conditions of 12 to 14 h photoperiod increase number of florets, spike length and percentage of flowering.
• Low light intensity causes failure in flowering.
• High light intensity without proper temperature also affects growth adversely.
• Corm storage at 3 to 7oC is good for better growth and flower production.
