was lower than that on the primary rachis branch. On the other
hand, the rate of milk white grains and white belly grains
in higher position was lower than that of those in a lower
position. Moreover, the rate of milk white grains and white
belly grains on the primary rachis branch was lower than that
on the secondary rachis branches. The rate of milk white grains
and white belly grains was negatively correlated with amylose
content. It is concluded that reducing the number of grains on
the secondary rachis branches is important to improve quality
(Igarashi 2008).
Most amino acids including 4-amino butyrate (GABA) a
tripeptide, glutathione in both oxidised and reduced forms,
and amines such as putrescine increased in response to low
temperature, including proline, etc.
