Seed Germination and Development

These are important part of seed except

• Embryo

• Ovul

• Spores

• Testa

Seed germination is a process of

• Transformation of embryo to seeds

• Transformation of embryo to seedlings

• Transformation of the physiology of seed

• Transformation of seed to flower

Which of the following describes the seed components

• Starch, protein, carbohydrates, mineral

• Starch, protein, fat, mineral

• Starch, protein, lipid, nutrient

• Starch, protein, fat, macro nutrient

Imbibition of water increases imbibant volume, which results in imbibitional pressure (IP)

• False

• True

ABA is an enzyme that support the growth and development of plant

• True

• False

Cytokinin involves primarily in cell growth and differentiation, and also affect apical dominance, axillary bud growth, and leaf senescence.

• False

• True

Below are sentence describing lag period in oxygen consumption except:

• Triggering agent stimulus activation & synthesis of germinating agent.

• Action of terminating agents on the genetic materials - new RNA & enzymes

• Triggering in activating the enzymes particularly ABA in developing seeds

• Embryo exhausts the available respiratory products & await more hexose from hydrolysis.

When seed moisture content (m.c) is low, usually <50% seed is still considered in developmental mode.

• True

• False

Developing embryo is surrounded with

negative osmotic potential environment, thus prevent embryo from germinating.

• True

• False

Below are the mechanisms of GA in controlling germination EXCEPT:

• The induction of the expression of hydrolyzing enzymes of endosperm tissues.

• Regulate production of mRNA during late embryogenesis to produce a particular set of proteins called `Late Embryogenesis Abundant' or LEA. Important in seed to withstand desiccation.

• Direct simulating effect on the growth potential of the embryo which this growth potential is restricted by ABA
