The bonds between amino acids in polypeptides (proteins).
Term
Photoperiod sensitivity
Definition
Found in soybeans. Soybeans are short-day plants: they will not flower unless there is appropriate night length (as days draw in). Only northern varieties and early-maturing soybeans lack photoperiod sensitivity. This discovery in 1920 contributed to the popularity of soybeans; it was fundamental in creating commercial cultivars adapted to different latitudes.
Term
Phospholipids
Definition
A major component of all cell membranes. Has 2 long fatty acid chains ("tails") joined by a glycerol molecule to a phosphate group (the "head"). The head is hydrophilic and the tails are hydrophobic, causing phospholipids to form bilayers.

Term
Planting date
Definition
A factor in soybean management. Early planting gives yield response in most years, but increases risk of frost damage. Rule of thumb: when a grower is done planting corn, continue with soybeans. The optimum date will be earlier the further south you are. Cruiser Maxx can offer some protection of yield when planting early.
Term
Planting depth
Definition
A factor in soybean managment. Standard is 1.5" deep, shallower if there is risk of crusting. It is more likely to plant to shallow than too deep. Try to plant into moisture, but if there is a choice between planting in dry soil or waiting for rain, plant in dry soil. There has to be good seed to soil contact for soybeans to take up water: 18 hours after germination plants must have water. Varieties vary in their ability to come up from depths.
Term
Pod abortion

Term
Pre-inoculant
Definition
A type of inoculant for soybeans. Applied to the seed weeks before planting by the seed company. Polymers protect the inoculant, and fungicide and insecticides are added. Makes it easier for a grower to decide on whether to use inoculants: removes the "hassle factor". Dyed a bright colour so that it is easy to distinguish from uninoculated seed.

Rate of dry weight accumulation is near zero. The plant stops growing, but matter may still be transferred to seeds from other parts of the plant.

Term
R8
Definition

Full maturity

The eighth reproductive stage in soybeans. 95% of pods have reached maturity. Most leaves have dropped from the plant. Another 7 - 10 days of suitable weather is required after R8, to allow beans to dry and reach ideal moisture content for harvest and storage (14% moisture).

Term
Seeding rate
Definition
A factor in soybean management. Usually aimed at 175,00 plants/ac. Later planting produces higher rates, up to 200,000 plants/ac. You want enough plants to fill the canopy as soon as possible. Seeding rate should be measured by the number of seeds/ac, not by weight; size of seed is taken into account. Only 75% of seeds planted will make it to maturity; a safety factor must be included to the number of seeds planted.

Term
Soybean
Definition

Glycine max

In the Leguminoseae family. A leguminous oilseed. Not considered a pulse, although they are equally important as a protein source in livestock rations and the human diet as they are as an oil source. Tetraploid, n = 10. Domesticated in China in the Shang Dynasty (3000 years ago), but were used for food long before domestication. Evolved to grow on the bungs of rice paddies. Very good nitrogen fixers; take more nitrogen from the soil than corn. Can tolerate "wet feet" very well. There were attempts to grow it in Europe in the 1700s but it was unsuccessful. In the 1800s soybeans were produced in small amounts in the US for soy sauce and as a forage crop. Samuel Bowen brought the first seeds to North America, and Henry Younge first grew them in 1766. The first soybeans in Ontario were grown on Pelee Island, and near Wallaceburg; early production was limited to Kent and Essex counties. Production in Ontario boomed 1980 - 2000. There are determinate, indeterminate, and semi-determinate soybeans. There are vegetative and reproductive growth stages. Soybeans are either crushing grade or food grade. Sources of information on varieites: Ontario soybean variety trials, company trials, farmer field trials, and on-farm experience.

Term
Soybean rhizobia
Definition
Soybean roots are infected with B. japonicum, and a nodule forms around it. The rhizobium bacteria live in the nodule, fixing N2 into N-containing compounds usable by the plant. In return, the plant provides the bacteria with sugars. Reduces the need for nitrogen fertilizers. Inoculants can be used to introduce rhizobium bacteria into the soil. To test if a soil has soybean rhizobia, grow two soybeans indoors so that one is inoculated. If the uninoculated plant is yellow and nitrogen-starved, there is no rhizobia in the soil.

A type of inoculant for soybeans. 30.4% yield increase. Made by first irradiating peat, then flooding it with rhizobium.
Term
Sulfur
Definition
Can come from acid rain, which is a product of pollution from steel plants, such as in Pittsburgh. Since environmental clean-ups at steel plants, there have been more sulfur shortages due to less acid rain.
Term
Sulfur deficiency
Definition
The plant tries to create polypeptides, but when it comes up on a cysteine or methionine (contain sulfur) in the sequence, it won't be able to add the amino acid, so it dismantles the whole polypeptide and starts over. This wastes a lot of energy. Looks a lot like a nitrogen deficiency, but adding nitrogen makes it worse because then the plant attempts to make proteins even faster, wasting even more energy.
Term

Term
Trypsin inhibitor
