Chapter 23, Problem 42A

Summary Introduction

To describe:

The reason why the grafted day neutral plant flowered before a non-grafted day neutral plant.

Introduction:

Angiosperm is a type of plant that flower at least once in their lifetime. Flower in the pants I induced by a complex combination of different hormones. Florigen is the main flowering hormone that induces the apical meristem to form flowers.

Explanation of Solution

The activation of apical meristem to make the flower is governed by the meristem sensitivity and the production of florigen. The meristem of the day neutral plant is highly sensitive to light and when in favorable condition (in a good amount of light for a particular duration), the meristem is activated soon and this is the result why the grafted plant flowers before the non grafted one.
