Layering differs from cuttings in that…
Initial rooting takes place while attached to parent plant

Teosinte Glume Architecture 1(TGA1)
-Function; Mutation Caused kernels to be naked.-Benefit to man; Easy to prepare and eat.-Disadvantage to plants: Seeds destroyed in the gust of wild animals.
Teosinte Branched 1(TB1)
-Function:Reduced tillering and branching of stalk.-Benefit to man: Small number of large ears.-Disadvantage to plants: Fertilization less efficient.
Days To Harvest
-Many-Function: Uniform time of flowering.-Benefit to man: Single harvest.-Disadvantage to plants: Subject to droughts, natural disasters.
Loss of Seed Dormancy
-Many-Function: Seeds germinate upon planting-Benefit to man: full stands of uniform grain.-Disadvantage to plants: Fall germination and death of seedlings.
PAR
-Photosynthetically Active Radiation
PPF
-Photosynthetic Photon flux-Amount of PAR Photons striking a unit area per unit of time.-Measured in micromols per meter squared per second.-Measures PAR between (400 to 700 nm)
PPF at noon on a summer day
200 umols m2- sec1-
PPF range for Photosynthetic compensation Point
-Varies from Species to species-generally between 30 and 120 umols m2- sec1-
Photosynthesis
6CO2+6H20–sunlight–>C6H1206+6O2
What is produced by light reactions?
-ATP-NADPH-These are used to fuel Calvin Cycle
What is produced by Dark reactions?
-Uses ATP and NADPH to produce sugar.
Respiration
C6H1206+6O2—->6CO2+6H2O+36ATP
