Because of its great influence on the taste and storage of instant noodle,and here, how to control the quality of the friture were mentioned, based on the analysis of the factors causing othe deterioration of the fri - ture.

For the moisture at 20～26%,however,the drying tehnique for moisture reduction should be applied to maitain safe storage, which was the only effective measure to protect the corn from deterioration.

The relationship between seed deterioration in 4 Brassica vegetativespecies and their fluorescent leachates was compared.

A mathematical model on procedure of some physiology and biochemical during aging of Chinese Fir seed;

The quality of seeds conditions the capacity of agricultural production,while seeds often undergo an irreversible declining of quality——deterioration or aging after reaching physiological maturity,which will result in a huge economic loss to the crop production.

The deterioration of cane quality showed differences in different sugarcane varieties.

Application and prospect of artificial mutation technology in medicinal plant breeding;

It elaborates that artificial mutation connected with crossbreeding,gene transfer and in vitro selection could raise the breeding efficiency and enlarge the field of breeding for disease resistant.
