VARIANCE OF THE MINERAL CONTENT FROM DIFFERENT ORGANS OF TWO PISUM SATIVUM CULTIVARS

The paper presents the content in mineral elements from the organs of two Pisum sativum cultivars namely: Gerola and Oregon Sugar Pod. The Oregon Sugar Pod is a west European cultivar little known in Romania characterized by a large vigor it can reach 150 cm height and by the fact that the edible organs are represented by pods. Determinations were made during flowery time, the analysed organs being the root, the stem, leaves from the superior half of the plant, basal leaves, flowers and edible organs. The content of mineral elements was determined in a larger amount in the Gerola cultivar. Analysis of mineral substances from the plant organs marked out a larger content in the roots (22,57% ), and the minimal quantity was found in the edible organs (7,89%). Analysis of mineral elements was made with an inductively coupled plasma spectrometer. Among the mineral elements, there has been determined the potassium percentage, which content varied between 632,95 mg./100g of dry substance in the seeds and 76,07 mg. /100g in the roots, calcium percentage that varied between 584,96 mg/100g in the basal leaves and 65,85 mg./100g in the pods, and magnesium percentage that varied between 374,52 mg. in the seeds and 26,16 mg. in the stem.
