On the Effects of PABA on Germination - Progress in Organic and Physical Chemistry: Structures and Mechanisms - page 259

The dynamics of activating of phenotype under act of PABA is evidently shown
on a histogram (Figure 1), reÀ ecting the middle indexes of levels of increases energy
of germination and winter hardness. The tendency of growth of middle indexes is
evidently.
FIGURE 1 Comparison of averages (totally on all cultures, %) of germinated capacity, energies
of germination of seed, and winter hardness of plants at the different methods of treatment of
ears of winter crops and panicles of kinds millet by PABA in the variants of experiments from 1
to 5 (see Tables 1-3) by comparison to control of I (without treatment, in tables - a zero variant).

20.5 CONCLUSION
(1) The method of acceleration of plant breeding process offers at sprouting of
mature seed in inflorescences of cereal cultures, ears of grain growing, and
panicles of millet. A method plugs the soakage of inflorescences in PABA
(concentrations of 0.1% and 0.2%) dissolved in an acetic acid.
(2) Dissolution of PABA in an acetic acid is more effective, than dissolution in hot
water (control II). Activating of phenotype at soakage in PABA, dissolved in
an acetic acid, in variants (3-5) was higher than in control II - at soakage in
PABA dissolved in hot water.
(3) Soakage of inflorescences during 3-4 hr in PABA a dissolved in an acetic acid,
gives the best result. More protracted soakage - 5-6 hr some reduces by all
variants.
(4) Concentrations of PABA applied to the treating of inflorescences were higher
than in the cited works in which treated trashed seeds.
