Abstract:
A pot experiment was
conducted in the Old Botanical Garden,
University of Agriculture Faisalabad, to
assess the effect of zinc uptake on
morphological, physiological and yield
attributes of wheat (Triticum aestivum L.).
Two varieties of wheat, i.e. W-141 and
W-142, procured from Ayub Agricultural
Research Institute (AARI), Faisalabad,
Pakistan, were used during this study. The
soil used during experiment was field soil
from university fields having sandy loam
texture. The experiment was laid out in a
completely randomized design (CRD) with
five treatments and four replicates. Different
treatments of zinc were applied on different
intervals. After 25 and 35 days of
germination, the plants were subjected to
three levels of ZnSO4 (0, 400 mgL-1, 600
mgL-1). During the experiment, the harvests
were taken after 10 days of intervals for
morphological and physiological analysis.
After the maturity of plants, final harvest
was taken and yield attributes were
recorded. Data of various morphological,
physiological and yield attributes were
statistically analyzed. The results showed
that zinc toxicity had adverse effects on the
wheat varieties. The variety W-141 was a
little bit tolerant to zinc toxicity, as per
shown by the results, as compared to
W-142, which suffered by the toxicity of
zinc. It was also revealed by the results that
zinc affects the morphological,
physiological and yield attributes of wheat
when applied in toxic concentration.
