210  Germination  of  Belladonna  Seed.    { Am'M°ayr' f9h:a7rm' 
fully  matured  berries  and  those  only  partially  matured,  since  all  of 
them  are  dried  and  shrivelled.  Consequently  a  slight  percentage  of 
immature  and  light  seed  is  likely  to  be  mixed  with  the  good  seed  and 
this  would  naturally  reduce  the  weight  on  the  average. 
Color  of  the  Seed. 
The  different  treatment  of  the  seed  has  a  distinct  effect  on  the 
color.  Lot  A  had  by  far  the  best  appearance,  the  seed  being  of  a 
uniform  silver  gray  color  with  a  fine  luster.  The  treatment  used 
with  Lot  B  resulted  in  a  nut-brown  color  with  no  luster  whatever. 
This  seed  had  a  very  poor  appearance.  Seed  from  Lot  C  had  the 
appearance  of  the  usual  commercial  seed,  and  consisted  of  both 
brown  and  gray  seed  having  only  little  luster. 
Germination  Tests. 
To  test  the  germination  of  seed  a  total  of  1,200  from  each  lot, 
i.  e.}  300  from  each  of  the  four  individual  plants,  were  planted  in 
flats  on  December  8,  19 16.  The  first  germination  was  noted  on  Jan- 
uary 3,  191 7,  and  on  January  9  the  first  count  was  made.  There- 
after the  seedlings  were  counted  at  convenient  intervals  and  after 
each  count  removed  from  the  flat.  In  Table  II  are  given  the  number 
of  germinated  seed  at  each  period.
