Lecture 4 Flashcards
Selection and Preparation of Planting Materials (16 cards)
For successful farming, use varieties recommended or approved by the ___________.
National Seed Industry Council (NSIC)
What are two kinds of planting materials?
use of seeds and vegetative parts
What are advantages of asexual over sexual methods? (TSES)
True-to-type
Smaller trees
Early fruit bearing
Seedless variety only option
SEEDS FOR PLANTING MUST BE: (PVD)
Physiologically mature, viable, and dormant
What pre-germination treatment technique soak seeds in water overnight?
Scarification
What pre-germination treatment technique is used to achieve flowering?
Vernalization
What other parts are removed for pre-germination treatment of seeds?
basal portion of the husk and mucilage from seeds
What technique/treatment is subjecting the seeds to cold treatments in order to break dormancy?
Stratification
What are the two methods of raising of vegetable seedlings?
Seedbed and seedbox method
State which seeds are prevented from germinating despite under favorable conditions.
Seed dormancy
What field planting method consists of fine sand or its mixture (50:50) with garden soil and seeds are sown closely within rows of appropriate distance?
Germination bed or seedbed
It is the practice of transplanting seedlings to individual bag or container to allow further growth of seedlings before field planting or grafting
Bagging or potting
It consists of either pure loamy garden soil (with high OM) or mixture (1:1:1) of garden soil, fine sand and compost
Potting media
It is the practice of transferring the seedling from one bag to another in order to provide greater rooting space
Rebagging
It is the practice of digging the seedlings (from the nursery bed) with a ball of soil still intact with the roots.
Balling
What are the four considerations for grafting? (YFES)
Yield, fruit quality improvement, environmental stress tolerance, soil-borne disease resistance
