Which propagation method is commonly used for gladiolus? (MCAER 2018)

✅Explanation:
Gladiolus plants are commonly propagated through corms, which are underground storage stems that resemble bulbs. Corms are planted in the ground and develop into new plants, producing additional corms that can be used for further propagation.

🔑Key point: :
-Gladiolus needs well drained sandy loam soil rich in organic matter with pH of 6 to 7.
-This crop requires minimum 10 hours of sunlight to overcome blindness.  
-Commercial propagation is through corms. Cold storage of corms at 3 to 7°C for 3 months or treatment with Ethrel (1000 ppm) or GA3 (100 ppm) or Thiourea (500 ppm) is adopted for breaking corm dormancy.
-Beds of size 6 x 2 m are prepared and corms are planted at a depth of 5 cm adopting a spacing of 40 x 25 cm (88,888 plants/ha) or 25 x 25 cm (1,60,000 plants/ha).  
-Varieties of gladiolus are Tropic Sea, White Prosperity, Priscilla, Summer Sunshine, Pusa Swarnima, Jackson Ville Gold, KKL.1.
