I n t e r a c t i o n of coumarln and l i g h t on the
germination of the seeds of Cajanus cajan.
Proc. Indian S c i . Cong. 62(3):92-93
(Abstract). 1166
Coumarln (1.0 x 10 2 m) i n h i b i t e d germination
of Cajanus oajan seeds and l i g h t had no
reverse action on the i n h i b i t o r y effects of
coumarln. Amino acids increased in the
axis of the control up to 72 and in the
cotyledons up to 48 hours a f t e r soaking,
whereas in the cou-treated, s l i g h t increase
was found a f t e r 24 hours, followed by
decrease. Sugars increased in the axis
a f t e r 48 hours in the control and decreased
gradually in the treated. The r e s p i r a t i o n
rate was greatly enhanced a f t e r 48 hours
in the control a x i s , whereas in the coutreated
ones the rate was s l i g h t l y enhanced
up to 24 hours followed by a decline.
Coumarln showed similar i n h i b i t i n g effects
both in l i g h t and dark.

The responses of the r a d i c l e , the plumule,
and the cotyledonary node are not i d e n t i ­
c a l . The phenomenon of apical dominance
prevails even in the embryonal stages. The
d i f f e r e n t i a t i o n of primary xylem takes
place independently in the plumule
(endarch), the cotyledonary node ( t r a n s i ­
t i o n ) , and the r a d i c l e (exarch). The
destiny of the organs has already been
determined.

The autonomous cytoplasmic inclusions,
namely lysosymes and mitochondria, which
were supposed to be the only centers of
the enzyme a c t i v i t y did not indicate any
a c t i v i t y . The reports about the d i s t r i b u ­
t i o n in nucleus and n u c l e o l i appear to be
more convincing f o r the c e l l s of the
r a d i c l e of the seedlings of Cajanus
indicus.

Maleic hydrazide, FW-450, and coumarln,
each applied as f o l i a r sprays of 0.55%, 1%,
and 1.5% concentrations, induce male s t e r i ­

of FW-450 applied before f l o r a l - b u d i n i t i a ­

The temperature in the germinating chambers
was alternated 8 hours 20°C and 16 hours
30°C. Dehradun paper and r o l l paper towel
gave equal r e s u l t s , s l i g h t l y higher than in
sand. Seeds were counted a f t e r 6 days and
f i n a l count was a f t e r 13 days. The germination
was constant at 25°C and 30°C. 35°C
temperature gave s l i g h t l y higher germinat
i o n .

The developing and germinating seeds of
C. indioue (Cajanus cajan) contained one
neutral and one acidic f r a c t i o n of gibberel
l i n - l i k e substances. The low a c t i v i t y of
these substances in developing seeds at
10 days a f t e r anthesis increased up to 30
days a f t e r anthesis and decreased therea
f t e r except for the neutral e t h y l acetate
f r a c t i o n (NEAF). Their high a c t i v i t y at
the 4th day of germination decreased up to
the 10th day a f t e r germination and increased
in roots and seedlings with age; the
acidic ethyl acetate and acidic chloroform
fractions showed a higher g i b b e r e l l i n - l i k e
a c t i v i t y than NEAF and acid butanol
fractions at a l l stages of germination.
