Q

Effects of Pruning:

A

a. reduces stored carbohydrates and leaf area available
for carbohydrate production
b. temporarily arrest apical dominance
c. excessive top pruning stimulates vegetative growth and
suppresses flowering but root pruning increases
flowering

23
Q

Advantages of Pruning:

A

a. a way of rejuvenating old trees
b. minimizing the bad effects of overcrowding, thus
reducing competition for light
c. a means of discarding unproductive plant parts

24
Q

A type of pruning Cuts where it is done by removing the terminal
portion of the shoot but retaining the
basal portion.

A

Heading back

25
Q

Increase branching in
flowering and foliage plants.

A

Pinching

26
Q

-done by removing the entire
shoots
- an extension of heading back.

A

Thinning out

27
Q

Types of chemicals for pruning

A

Cycocel
• Daminozide
• NAA

28
Q

t h e p h y s i o l o g i c a l r e a c t i o n o f
organisms to the length of night or a
dark period

A

PHOTOPERIODISM

29
Q

the developmental responses of
plants to the relative lengths of light
and dark periods

A

PHOTOPERIODISM

30
Q

The daylength which separates the inductive from the
non-inductive ranges of photoperiod.

A

Critical Daylength (CDL)

31
Q

In Critical Daylength (CDL) They are classified under three groups according to the
photoperiods:

A
  1. Long day plants
    2.Short day plants
  2. Day Neutral plants
32
Q

plants require a relatively short
day light period (usually 8-10
hours) and a continuous dark
period of about 14-16 hours for
subsequent flowering

A

Short Day Plant

33
Q

also known as long-night plants

A

Short Day Plant

34
Q

Examples of short day plants.

A

c h r y s a n t h e m u m ,
poinsettias, coffee, soybean,
tobacco
