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
