1. A change in the chemistry of a gene that is perpetuated in subsequent divisions of the cell in which it occurs; a change in the sequence of base pairs in the chromosomal molecule. 2. De Vries, term for the sudden production of a species, as distinguished from variation. [L. muto, pp.
Sugar or snow peas are grown for their flat, green pods. Peas are a cool-season crop that must mature before the weather gets warm. The ideal growing temperature for peas is 55Â°F to 70Â°F. Sow peas in the garden 6 weeks before the average last frost date in spring or as soon as the soil can be worked.How to plant and spacing.lanting time.

The non-germinating peas produced rates close to zero for both photosynthesis and respiration (means were -0.331 ppm/min/g and 0.021 ppm/min/g, respectively).However, rates of photosynthesis and respiration varied for the germinating peas (means were 1.793 ppm/min/g and 18.191 ppm/min/g respectively).Nevertheless, more experimental trials under the same conditions would be necessary to derive more accurate rates of photosynthesis and respiration.owever, rates of photosynthesis and respiration varied for the germinating peas (means were 1.793 ppm/min/g and 18.191 ppm/min/g respectively).
