Question

Grafting in monocots is rarely successful because

• A. they do not have cambium.
• B. they have open vascular bundles.
• C. they have very thick woody stems.
• D. they undergo secondary growth.

Answer 1

The correct option is A they do not have cambium.

Monocot plants lack cambium tissue, thus their vascular bundles are said to be of ‘closed’ type. The absence of cambium makes successful grafting nearly impossible in them. Cambium refers to the meristematic tissue that helps in secondary growth in the case of dicot plants. Cambium actively produces a lot of undifferentiated cells that can help the two stems to join together thereby leading to a successful grafting procedure. Most monocots are non-woody and have soft herbaceous stems.
