	_____________ is a common propagation method for agronomic, forestry, vegetable crops and woody plants for liner production.   Direct seeding Field seeding Stratification Pretreating seeds

	_________________ describes a check in plant growth that is observed following transplanting compared to direct-seeded crops. It is more severe if the transplants are too large and have confined root systems in the plug tray, or if the weather is unfavorable in the field.   Secondary dormancy Post-emergence Transplant shock Moist-chilling

	___________ describes the area where seeds will be planted and seedlings will emerge. It may be an entire field for field-seeded crops or a smaller area for future transplants.   Seed bed Field seeding Warm stratification seed planting

	______________ have altered shape that makes them easier to sow with precision seeding machines. The coating may also improve flowability, which is the ability for seeds to flow out of the seeder.   Synthetic seeds Certified seeds Treated seeds Coated seeds

	______________ use gravity and tractor speed to place seeds in the ground, while ____________ use belts, plates or vacuum to place single seeds at a selected seed spacing   Precision seeders, wheel seeders Gel seeders, precision seeders Vacuum seeders, random seeders Random seeders, precision seeders

	________________ contain seeds sown at high density in the field for future transplanting to a wider spacing.   Seed hoppers Field nurseries Seed coating Nursery row production

	The _____________ seeds are sown in the field depends on the required temperature for germination, need for satisfying dormancy conditions, or the time the seed crop matures for recalcitrant seeds.   spacing of time of day number of time of year

	___________ is a treatment that allows water to penetrate seeds with a hard seed coat. This may be physical, chemical (acid) or involve high temperature.   Scarification Stratification Priming "Chilling"

	______________ is a period of moist warm or chilling conditions that satisfies dormancy in seeds with endogenous, physiological dormancy.   Hot water treatment Scarification Stratification Priming

	One way to produce liners of budding ornamental or fruit trees is to __________ them in field rows.   precision seed random seed hand sow direct seed

	A ____________ uses passive solar heating to protect transplants. They are often used as a transition environment for transplants between greenhouse and field conditions that are used to "harden" transplants and reduce transplant shock   cold frame greenhouse hotbed growth room

	________ are small-celled transplant flats used to produce many seedlings in a small greenhouse area.   Liners Bedding plants Suckers Plugs

	Large bedding plant producers use _____________ to control germination conditions to optimize seedling emergence in plug flats.   Hotbeds Greenhouses Growth rooms Cold frames

	_______________ is required for large-scale production of vegetable and flower seeds for greenhouse production. This is because seed size is small and large quantities of seeds must be precisely sown in each small plug in the flat.   Mechanical sowing Direct seeding Precision seeding Random seeding

	__________________ reduce labor costs and can provide more even moisture to plug trays.   Greenhouses Hoses Automated watering systems Bottom heat

	Temperature control for bedding plant seed germination can be critical to seedling emergence. ____________ provided by recirculating hot water systems are common for spring seeded crops.   Bottom heat Moist-chilling Warm stratification Hot water scarification

	_______________ during transplant production can be provided by treating seedlings with chemicals or controlling the environment. This may be simply done by manipulating temperature and water.   Damping-off "Stretching" Hardening-off Height control
