REPRODUCTION IN FOREST TREESAnand Charvin.G

INTRODUCTION

Reproduction is the process by

which plants and animals give rise

to offspring and which

fundamentally consists of the

segregation of a portion of the

parental body by a sexual or an

asexual process and its subsequent

growth and differentiation into a

new individual.

TYPES OF REPRODUCTION There are two types of reproduction in plants:

Sexual & Asexual reproduction.

Sexual reproduction occurs in plants though reproductive

parts of the plant.

While asexual reproduction is through vegetative

propagation.

POLLINATION

Pollination is a process by

which pollen is transferred

from the anther to the stigmaof the plant, thereby enabling

fertilization and reproduction.

TYPES OF POLLINATION

SELF POLLINATION

Self-pollination is when pollen from the same plant arrives at the stigma of a flower or at the

ovule.

There are two types of self-pollination: In autogamy, pollen

is transferred to the stigma of the same flower. In

geitonogamy, pollen is transferred from the anther of

one flower to the stigma of another flower on the same

flowering plant.

CROSS POLLINATION

The transfer of pollen from

an anther of a flower of

one plant to a stigma of a flower of another plant of

the same species. Also

called allogamy,

xenogamy.

ASEXUAL REPRODUCTION

Asexual reproduction refers to the process of reproduction in plants

without the involvement of reproductive parts, rather the vegetative

parts of the plant such as stem, leaves and roots, in general

produce young plants.
