Abstract:

Fenugreek (Trigonella Foenum Graceum)
is one of the medicinal plants that have been used as a folk
medicine in Iran and many countries. In this study, effects
of macronutrient element shortage (Nitrogen, Phosphorous,
Potassium, Magnesium and Calcium) on dry and fresh weight,
root and shoot length, Leaf Relative Water and chlorophyll
content in Fenugreek plant was investigated. In relation to
Magnesium shortage which caused, increase of root and shoot
dry weight, root and shoot fresh weight, root and shoot
length and leaf relative water content, it was observed that
this increment was meaningful in 0/05 of statistical level.
In Calcium shortage, root and shoot length, root and shoot
dry weight and shoot fresh weight decreased, which in
statistical level 0/05 showed meaningful difference than
blank level, while in relation to leaf relative water
content, there was no meaningful difference to the control
level. In Potassium shortage, shoot length, root and shoot
fresh weight and leaf relative water content meaningful
increased, while root and shoot dry weight, observed
decrement in statistical level of 0/05 which was meaningful
than blank level. Investigating the effect of Phosphorous
shortage, shoot length meaningfully increased than in blank
level, while in root dry weight, shoot fresh weight and leaf
relative water content, meaningful decrement was observed
than in the blank level (P<0.05). In Nitrogen shortage, root
length and fresh weight and leaf relative water content
meaningfully increased than blank, while shoot fresh weight,
root and shoot dry weight were meaningfully decreased in
statistical levels of 0/05 than blank. Macronutrient
elements shortage caused decrement of chlorophyll in
Fenugreek leaves with Nitrogen, Potassium and Phosphorous
recording shortage than the blank level. In plants with
Calcium and magnesium shortage, increase of chlorophyll was
observed. Macronutrient elements shortage caused meaningful
decrease in chlorophyll b and total chlorophyll
concentration in Fenugreek leaves (P<0.05). Also,
macronutrient elements shortage caused decrease in
Malondialdehyde activity in root and shoot of Fenugreek
plant.
