Changes in Mineral Profile and Morphological Traits of Pea (Pisum sativum L.) as Influenced by Fusarium oxysporum F. Sp. Pisi under Natural Conditions

Rana Muhammad Sabir Tariq, Shahbaz Talib Sahi, Tanveer Ahmad and Abdul Hannan

Eight pea varieties including three commercial and five advance lines were cultivated under natural conditions for the infection of Pea wilt disease. Only four varieties were found susceptible to Fusarium wilt. Infected and healthy samples were collected from each variety. After pathogenecity of Fusarium oxysporum F. sp. pisi, the mineral and growth parameters from each sample were recorded. The parameters of healthy and infected samples were compared within each variety. Nitrogen was slightly increased (21.09%) after the onset of infection. While infected samples showed a decline in Phosphorus (44.38%), Potassium (53.64%), Calcium (23.60%), Magnesium (57.24%), and Zinc (32.22%). Growth parameters were also influenced negatively after the infection. They included fresh plant weight (68.79%), dry plant weight (57.29%), shoot length (50.43%) and No. of pods/plant (100%) while root length remained un-affected as compared to non-infected plants. These studies explained the role of vascular infection on the physiology and morphology of Pea.
