Consider the following statements : 1. Sweet orange plant is propagated by grafting technique 2. Jasmine plant is propagated by layering technique. Which of the statements given above is/are correct ?

Result
Your answer: —  Â·  Correct: C
Explanation

Both statements are correct. Sweet orange (Citrus sinensis) is commonly propagated by grafting/budding in commercial and horticultural practice; shield budding (a form of bud grafting) is specifically used for sweet orange propagation to combine desired scion varieties with rootstocks [1]. Jasmine species are frequently propagated vegetatively by layering (including ground and air layering), which allows mature stems to root while still attached to the parent plant and is a standard method for establishing new jasmine plants. More generally, vegetative methods such as grafting, budding and layering are used to propagate plants that have limited seed set or when clonal uniformity is required, and both orange and jasmine are cited among such crops [2].
