Developing of pea

Quantitation. Combined GC-SICM has been used mainly for quantitation. For a particular GA the absolute intensity of a characteristic ion in its mass spectrum is related to the amount of GA present, using standards to calibrate the instrument. Frydman et al. (35) used this "external standard method" to measure the levels of a number of GAs throughout the development of pea seeds. An alternative and preferable approach employs...

(B) Changes in fresh weight ( ) and protein content (a) during development of pea cotyledons. Vertical arrows indicate the stages of development at which the storage proteins vicilin and legumin can first be detected.

APES are biodegradable but often lack good mechanical and physical properties, whereas aliphatic polyamides have good mechanical properties but are not biodegradable. Achieving a successful combination of both favorable properties has been the reason for the development of PEAs [119].
