Using silver (either as nano silver or silver nitrate) had a
significant effect on silver concentration in the plant
shoot, number of leaves, height of the plant, plant dry
weight, inflorescence dry weight, seed yield, weight of
100 seeds, and polyphenol and tannin content in shoot
(Table 1). In contrast, the length, width, and greenness of
leaves have not affected by silver treatment (Table 1). Silver
concentration in shoot was increased by all treatments
(either nano silver or silver nitrate) However, the higher
concentration of silver in the shoot was obtained by silver
nitrate treatment in comparison to others (Figure 1).
There was no significant difference between 100 ppm of
silver nitrate and 60 ppm concentration of nano silver on
the shoot silver concentration (Figure 1).
The highest number of leaves was obtained by spraying
100 ppm of silver nitrate, while the lowest was seen in
control plants (Table 2). The number of leaves and plant
height was improved by increasing the concentration of
nano silver while they were reduced by rising in silver
nitrate concentration. The longest height of the plant was
obtained with the treatment of nano silver 60 ppm, while
the lowest amount of this feature was seen with control
(Table 2). However, by going up, the concentration of
silver nitrate from 100 to 300 ppm caused a decrease in
the dry weight of plant and dry weight of inflorescence. In
contrast, a raise in the concentration of nano silver from
20 to 60 ppm has led to an improvement in those parameters
(Table 2). Raising the concentration of silver nitrate
from 100 to 300 ppm caused a decline in the seed yield,
but an increase in concentration of nano silver from 20 to
60 ppm leads to arise in the seed yield. The lowest amount
of seed yield was found with control samples, and the
highest was obtained by silver nitrate 100 ppm treatment.
However, seed yield was found to be more than the
control sample with different concentrations of nano silver
and silver nitrate (Table 2). The highest weight of 100
seeds was observed in the control sample, while this
weight was decreased when either nano silver or silver
nitrate was applied (Table 2).
The highest content of polyphenol and tannin was observed
in control, and the lowest content was observed
with silver nitrate 100 ppm (Table 2). The polyphenol
and tannin content was raised with the increasing level
of silver nitrate but was decreased with the increase in
nano silver. The greenness, length, and width of the
leaves were not affected by nano silver and silver nitrate
treatments (Table 1).
