PLNT 1213 Lecture Notes - Lecture 12: Broadcast Spreader, Intraspecific Competition, Soil
Document Summary
A grower must choose seed that is: an appropriate species, an appropriate variety, of high quality. What is marketable: commodity vs. niche market, infrastructure, demand. What is adapted: light, temperature, water requirements. Other desirable traits (blue corn, for example) An indicator of the ability of a seed to develop into a productive plant. The ability of a seed to germinate under favorable conditions. One way to quantify viable seeds is to calculate the percent germination. Germination: the process of resuming growth in a seed. Count the number of seeds that germinate normally. Example: a seed analyst is conducting germination tests on a sample of peanut seeds. After 3 days, she notes that 47 out of 50 seeds have developed normal seedlings: what is the percent germination, 47/50*100 = 94, purity. Measures the percentage by weight of the desired seed in the sample. You are a seed analyst for pioneer hi-bred seeds at their seed corn production facility in cherokee, ia.
