When the branches of a plant growing in the field are pulled towards the ground and a part of them is covered with moist soil (leaving the tips of the branches exposed above the ground), then after some time new roots develop from the parts of branches buried in the soil. On cutting these branches from the parent plant, new plants are produced from the cut parts of branches which had developed roots.
(a) What is this method of propagation of plants known as?
(b) What type of branches should a plant have to be able to be propagated by this method?
(c) Name any two plants which are grown for their flowers and propagated by this method.
(d) Name any two plants which are grown for their fruits and propagated by this method
(e) Name one plant which gets propagated by this method naturally by forming runners (soft horizontal stems running above the ground).
उत्तर
(a) This method of propagating plants is known as layering.
(b) To get propagated by this method, a plant should have soft horizontal branches.
(c) Jasmine and China rose are the two plants that are propagated by this method for their flowers.
(d) Guava and lemon are the two plants that are propagated by this method for their fruits.
