Read the given statements and identify the plant hormones X,Y and Z. (i) Hormone Y induces flowering in mango and also promotes rapid internode/petiole elongation in deep water rice plants and hence helping leaves or upper part of shoot to remain above water. (ii) Hormone X promotes root growth and root hair formation. (iii) Hormone Z inhibits the seed germination, increases the tolerance of plant to various stresses, play important role in seed development, maturation and dormancy.
