ABSTRACT

The effect of weed extracts of Ageratum conyzoides L., Chenopodium album L,
Cynodon dactylon (L.) Pers., and Parthenium hysterophorus L. were examined on the
seed germination, seedling growth, chlorophyll, proline and total protein content in
wheat (Triticum aestivum L.) varieties (PBW-154, PBW-343, PBW-373, PBW-443, PBW502,
RR-21, UP-262, UP-ll09, UP-2382 and UP-2425). Weed extracts decreased
germination (%) at the end of experiment (after 8 days) in all wheat varieties except
in PBW-502, RR-21, UP-262, UP-ll09 and UP-2382. The seedling growth (both length
and dry weight) was reduced, along with chl-a and chl-b content, and proline (a
stress amino acid ) content increased in all the varieties compared to control. Among
the four weed extracts, the inhibitory effect on different varieties of wheat on these
parameters followed the order: P. hysterophorus > A. conyzoides > C. album and >
C. dactylon. However, the total protein content was either increased or decreased in
all the varieties compared to control. Among the varieties, RR-21, UP-2382 and UP2425
were resistant; PBW-343, PBW-373, PBW-502 and UP-ll09 were susceptible
with different weed extracts.
