[#81] In-situ method of grafting in mango is
Correct Answer
(A) Inarching
Explanation
Solution: The in-situ method of grafting in mango is Inarching . Inarching is a technique where a young seedling or rootstock is used as a support for the scion (the part of the plant being grafted). The scion and rootstock are joined together at the base, typically in the nursery or field, and both plants are allowed to grow together until they form a stable union. This method is commonly used for mango grafting, especially when the desired variety of mango is grafted onto a rootstock that is resistant to diseases or pests. Option B: Stone Grafting This option is incorrect . Stone grafting involves the use of the seed or stone from a fruit to grow a new plant, but it is not an in-situ grafting method used in mango. Option C: Epicotyl Grafting This option is incorrect . Epicotyl grafting is a method where the graft is made on the epicotyl (the portion of the stem above the cotyledons), and while it may be used in some plants, it is not typically used in mango. Option D: Soft Wood Grafting This option is incorrect . Softwood grafting involves grafting onto young, flexible shoots, but this is not considered an in-situ method for mango grafting. Therefore, the correct answer is Option A: Inarching , as this is the appropriate in-situ grafting method for mango cultivation.
