D+ 15 and D+ 40 are situated well on the normal curve, but also the point corresponding to the epicenter at D+ 40 clearly fits the same curve. The correlation being y = -2.11x + 11.56, for x = 1.9, the theoretical value for y (amino acids) is 7.55, whereas the observed value is 6.91 (i.e., a 8.5% deviation). This point is however situated at the extreme part (i.e., the lower chlorophyll concentrations and the higher amino acids ones).

 

A Particular Relation Between Leucine or Isoleucine and ß Carotene Was Also Found in Barley Leaves (Bounias, 1975). The same type of relation was found by plotting all the samples that could be considered as controls (Figures 5A and B). Taking into account the hyperbolic shape of the curves in natural units, plotting isoleucine or leucine versus the reciprocal of ß carotene concentrations (Figs. 5C and 5D) led to positive correlations of higher significance (Table 12).
