there are two types of this embryo leaf, the _______ & _____

Study These Flashcards
A

cotyledons

22
Q

Give the 3 functions of a seed coat

Study These Flashcards
A
  1. Protects the seed from mechanical or physical damage
  2. Prevents the seed to germinate even in favorable conditions
  3. Prevents excessive water-loss from the seeds
23
Q

Give the 2 functions of the seed endosperm

Study These Flashcards
A
  1. Stores reserve food that provide nourishment to the developing plant
  2. Protects the embryo, by acting as a mechanical barrier
24
Q

Give the 2 functions of the seed embryo

Study These Flashcards
A
  1. Gives rise to a complete new plant
  2. Stores food and provide nourishment to the new plant
25
It is the art of placing seeds in the soil to have good germination in the field.
Sowing
26
What are the 7 methods of sowing seeds?
1. Broadcasting 2. Dibbling 3. Seed Dropping Behind the Plow 4. Drilling 5. Transplanting 6. Hill Dropping 7. Check Row Planting
27
the method of random scattering of seeds on the surface of seedbed. It can be done manually or mechanically.
Broadcasting
28
the process of placing seeds in holes made in the seedbed and closing the seed with soil. In this method, seeds are placed in holes made at definite depth at fixed spacing.
Dibbling
29
Most vegetables are sown in this method.
Dibbling
30
consists of dropping the seeds in furrow lines in a continuous stream and covering them with soil.
Drilling
31
consists of rising the seedlings in a nursery bed and then planting the seedlings in another field (main field). It is commonly done for paddy, vegetable and flowers.
Transplanting
32
In this method, few seeds are dropped as a hill at a fixed place and not in a continuous stream.
Hill Dropping
33
It is a method of planting, in which row-to-row and plant-to-plant distance is uniform. In this method, seeds are planted precisely along straight parallel furrows.
Check Row Planting
34
What type of film/mulch is used during rainy season?
Perforated Film
35
What type of film/mulch is used in Orchards and Plantations?
Thicker Mulch
36
What type of film/mulch is used when implementing soil solarization?
Transparent Film
37
What type of film/mulch is used when controlling weeds through solarization?
Thin Transparent Film
38
What type of film/mulch is used when implementing weed control in cropped land?
Black Film
39
What type of film/mulch is used in sandy soil?
Black Film
40
What type of film/mulch is used during saline water use?
Black Film
41
What type of film/mulch is used in summer cropped land?
White Film
42
What type of film/mulch is used as insect repellant?
Silver-colored Film
43
What type of film/mulch is used during early germination?
Thinner film
44
What are the important parameters to consider when choosing plastic film?
1. Thickness 2. Width 3. Perforations 4. Mulch Color
45
Normally the _________ of the film does not affect the mulching effect except when it is used for colorization. But some of the recent references do indicate its impact on crop yield.
Thickness
46
What is the normal width of the film that can adapt to different conditions?
One and a half meters.
47
The ____________ of a film mulch may be advantageous under some situations and disadvantageous for some other situation.
Perforations
48
The capillary movement of water and fertilizer distribution will be better and more uniform under ___________ condition.
Imperforated Film
49
Prevention of water stagnation around the plants, is better. But it has got the disadvantages of encouraging weed growth.
Perforated Film
50
What factors does the color of the mulch affect?
1. Soil temperature 2. Air temperature around plants 3. soil salinity
51
Which color type of film deposits more salt on soil surface?
Transparent
52
This color type of film restricts water movement and upward movement of salt is reduced.
Black Film
