Lecture 4: SELECTION AND PREPARATION OF PLANTING MATERIALS Flashcards
for successful farming, use varieties recommended or approved by the ____________________________ (NSIC), an agency under the Department of Agriculture
National Seed Industry Council
such varieties after having been bred and undergone rigid testing and evaluation were
o proven to have good yield
o desirable quality
o resistance to pest and diseases, and
o other desirable traits
KINDS OF PLANTING MATERIALS
a. use of seeds (sexual propagation)
b. use of vegetative parts (asexual propagation)
KINDS OF PLANTING MATERIALS
applicable to most annual crops (agronomic,
vegetables, plantation crops)
seeds (sexual propagation)
KINDS OF PLANTING MATERIALS
used as rootstocks for grafting and budding of tree crops
seeds (sexual propagation)
KINDS OF PLANTING MATERIALS
applicable to most fruits and ornamental crops, some agronomic crops, some plantation crops and few vegetables
vegetative parts (asexual propagation)
KINDS OF PLANTING MATERIALS
examples of vegetative parts
roots, leaves, stems
ADVANTAGES OF ASEXUAL OVER SEXUAL
METHODS
true-to-type plants
-with same traits
-smaller trees
-starts bearing fruits early
-only option for seedlees varieties
SEEDS FOR PLANTING MUST BE:
-physiologically mature
-should be viable
PRE-GERMINATION TREATMENT OF SEEDS
- scarification
- removing basal portion of the husk (coconuts)
- removing mucilage from seeds
- vernalization
- stratification
PRE-GERMINATION TREATMENT OF SEEDS
treatment that improves the permeability of the seedcoat to water and hasten seed germination
scarification
PRE-GERMINATION TREATMENT OF SEEDS
soaking seeds in water overnight
an example of?
scarification
PRE-GERMINATION TREATMENT OF SEEDS
soaking seeds in acid
an example of?
scarification
PRE-GERMINATION TREATMENT OF SEEDS
remove endocarp
an example of?
scarification
PRE-GERMINATION TREATMENT OF SEEDS
rubbing seeds with hand and sand removes what?
mucilage
