Question

Mango and guava are propagated through
(a) Tissue culture
(b) Grafting
(c) Stem cutting
(d) Layering

Answer 1

Hint: It is a rapid vegetative propagation technique to multiply plants identical to the desired parent tree. The grafting of trees done on dewars rootstock is less vigorous so more trees are often accommodated per unit of land. The scion ought to be taken from an effective tree that produces standard quality leafy foods.

Complete answer
Mango and guava are propagated through grafting. It is a cultivation method where the living withdrawal of a bit of the plant is utilized to recover the development. One plant is chosen for its roots and this is often called the stock or rootstock. The other plant is chosen for its stems, leaves, flowers, or fruits and is named the scion. The joining of scion and stalk is understood as inosculation. The techniques are mostly utilized in the asexual mode of reproduction.

Additional information
Plants grafting principles:
• Involves joining or uniting two separate woody parts of living plant parts from different trees or plants to make one plant.
• Parts utilized in grafting: Scion; refers to the bud or piece of stem that's to be attached to the rootstock. Rootstock alludes to the seedling or tree whereupon a scion is to be connected. Materials selected as scions should be taken from terminal buds (end of a branch) of a tree or plant, at the ‘tight bud stage’ or before a replacement flush with buds which are swollen but haven't opened.

So the correct answer is ‘Grafting’.

Note: The grafting of mango trees, or other trees, is the practice of transferring a bit of mature, bearing tree, or scion to a separate seedling called the rootstock. The scion becomes the cover of the tree and therefore the rootstock the lower trunk and rootage. Mango tree uniting is the most dependable and practical strategy for mango engendering.
