| Question | Answer |
|---|---|
| What type of emergence does corn, wheat, and field pea have? Epigeal or Hypogeal? | Hypogeal |
| All the seeds have been coated. What is the purpose of addins the coat? | Adds weight and makes planting more uniform |
| Which crop has a growing point above ground after emergence is complete? Corn or soybeans? | Soybeans |
| This wheat variety has a seed size of 14,000 seed/lb. How many pounds per acre are needed to get 1 million seeds/acre? | 71 lbs |
| What is the name of the 2 structures of canola? Because they are above ground are they epigeal or hypogal? | Cotyledons; Epigeal |
| What is the first root that develops after seed germination is complete? | Radicle |
| What is the structure that emerges from the soil for corn and wheat? | Coleoptile |
| Determining graph moisture is criticle for determining when the graph is ready for harvest. What is the standard moisture for corn? For soybeans? | Corn: 15.5% Soybeans: 13% |
| Why do seed companies put color dyes on seeds that farmers buy? | To indicate the seeds are treated with pesticides |
| What structure is attached to oat and barley seeds, but reattaches from wheat during harvest? | Hull (lemma, palea) |
| What seed part is used to make soybean and canola oil? | Embryo (Cotyledons) |
| This sample is the animal feed called distillers grain, which is a by-product of corn for ethanol. Which compound is more concentrated in distillers compared to the whole corn kernel? | Proteins |
| What seed part is used to make all-purpose flour? | Endosperm |
| What seed part is present in brown rice but is missing in white rice? | Seed Coat |
| What is the name of the part between the seed and the crown roots on corn? | Mesocotyl |
| What is the name of the tissue that actively grows for soybeans to emerge? | Hypocotyl |
| If I were to plant this soybean seed, what seed quality problems exist? | Cracking and Other Seeds Present |
| This animal feed is a by-product of converting sugar beet roots to sugar, what is it called? | Sugarbeet Pulp |
| What does "MF" and "MR" tell me about these two corn hybrids? | Medium Flat and Medium Round |
| If environmental conditions are average, how many days from emergence will it take for this corn hybrid to reach black layer? | 111 Days |
| This corn hybrid has two varieties at 94% of one and 5% of the other. Why are there two varieties? | Refuge Corn Seed |
| Why can corn sucessfully emerge from deeper seeding depths than wheat? | Corn has two emerging parts and Wheat only has one |
| What is the percent germination of this corn seed? Based on germination, how many seeds/acre are needed to activate 40,000 plants/acre? | 95%;42,105? |
