Abstract: Forty species
related to 21 families were identified as the weeds of wheat from
village Lahor, District Swabi during April 2005. Poaceae (7 spp),
followed by Brassicaceae (5 spp), Caryophyllaceae, Asteraceae and
Fabaceae (each with 4 spp) were the important families. The remaining
families had single species. The most frequent species with more than
45% average frequency were Anagallis arvensis L., Arenaria
serphyllifolia L., Chenpodium album L., Fumaria indica
(Hausskn) H. N. Pugsley., Melilotus indica (L.) All., Rumex
dentatus (Meissn) Rich., and Veronica biloba Linn. Based on
importance value four communities viz., Arenaria
-Anagallis-Chenopodium, Fumaria-Rumex-Chenopodium,
Fumaria-Chenopodium-Anagallis, Arenaria-Fumaria-Chenopodium
were deciphered. Caryophyllaceae, Fumariaceae, Chenopodiaceae, Fabaceae,
Poaceae and Primulaceae were the dominant families on the basis of
family importance values. The biological spectrum showed that there were
82.5% therophytes and 12.5% hemicryptophytes. Geophytes and chamaephytes
were represented by one species each. Leaf spectra consisted of 42.5%
microphylls, 35% nanophylls and 22.5% leptophylls. Biomass of the forbs
was higher than the grasses. Species diversity was higher in Koz Mulk
and Pani owing to crop rotation.
