Environmental conditions and type of cuttings on rooting and growth of vanilla ( Vanilla planifolia Andrews)

摘要

The effects of environmental conditions (poly-house, greenhouse with mist, 50% shade net and natural shade) and type of cuttings (single, three, and five nodes) on rooting and growth of vanilla ( Vanilla planifolia Andrews) were evaluated. Results show that greenhouse is more conducive for producing longer sprouts with greater number of leaves. It also resulted in early rooting and high rooting percentage. As regards to type of cuttings, five node cuttings were the best as it resulted in early sprouting and rooting, higher sprouting percentage, longer and thicker roots, and higher fresh and dry weight of shoot and roots compared to single and three node cuttings.
