End of Question 1


Question 2
2
Open Hint for Question 2 in a new window		 ___________________are any environmental factors (relative humidity, temperature, light, and gases, etc.) in the immediate vicinity of the propagule during propagation.
 
End of Question 2


Question 3
3
Open Hint for Question 3 in a new window		 A___________ is used for regenerating plants and can include cuttings, seeds, grafts, layers, tissue culture explants and single cells.
 
End of Question 3


Question 4
4
Open Hint for Question 4 in a new window		 ______________ are small seedling plants.
 
End of Question 4


Question 5
5
Open Hint for Question 5 in a new window		 ________________ are plants produced asexually from layering such as air layering or stooling.
 
End of Question 5


Question 6
6
Open Hint for Question 6 in a new window		 The ______________ is the zone of soil immediately adjacent to plant roots in which the kinds, numbers, or activities of microorganisms differ from that of the bulk soil.
 
End of Question 6


Question 7
7
Open Hint for Question 7 in a new window		 __________________ is partial reduction of light to 100% light exclusion that can occur during stock plant manipulation and/or propagation.
 
End of Question 7


Question 8
8
Open Hint for Question 8 in a new window		 ___________________ is a form of layering in which the shoots are cut back to the ground, covered with soil, and adventitious roots are initiated on shoots while still attached to the plant. The rooted stem (layer) is than detached and becomes a separate plant on its own roots.
 
End of Question 8


Question 9
9
Open Hint for Question 9 in a new window		 ________________ is the stress adaptation process or acclimation that occurs as a propagule, such as a cutting, is gradually weaned from a high to a low relative humidity environment during rooting. In micropropagation (tissue culture) acclimation is referred to as acclimatization.
 
End of Question 9

End of Question 12


Question 13
13
Open Hint for Question 13 in a new window		 ___________________ are vacuum-operated radiant heaters installed in the ridges of greenhouses with the concept of heating the plants but not the air mass.
 
End of Question 13

14
Open Hint for Question 14 in a new window		 _______________ are used to reduce heat loss at night by creating a barrier between the crop and greenhouse roof and walls.
