Correct Option
Both Statement 1 and Statement 2 are correct.
Statement 1 is correct. Sweet orange (Citrus sinensis) is commonly propagated through grafting. In this technique, a scion (a shoot or bud from the desired sweet orange variety) is joined with a rootstock (the lower part of a compatible plant, often chosen for its disease resistance or adaptability to soil conditions). This method ensures the new plant retains the desirable fruit characteristics of the scion while benefiting from the rootstock's attributes.
Statement 2 is correct. Jasmine (Jasminum spp.) is typically propagated by the layering technique. This involves bending a branch of the parent plant to the ground, covering a portion of it with soil while it is still attached to the parent, and allowing it to develop roots. Once sufficient roots have formed, the rooted branch is detached from the parent plant and grown as an independent individual.
Incorrect Options
Options (A), (B), and (D) are incorrect because both statements provided are factually accurate regarding the propagation methods for sweet orange and jasmine plants, respectively. Therefore, selecting only one statement as correct or neither as correct would be erroneous.
