INFLUENCES OF THE SOIL PHYSICO-CHEMICAL CHARACTERISTICS ON THE MINERAL COMPOSITION OF THE MOROCCAN STRAWBERRY TREE (Arbutus unedo L)

Abstract

Leaf mineral composition reflects the complex interaction between soil, climate, and plant genetic and epigenetic background in terms of organic and inorganic composition. The present study aimed to evaluate the effect of seven soil compositions on the mineral contents of Strawberry leaves (Arbutus unedo) under Moroccan conditions. The obtained results demonstrated a significant positive correlation between the soil nitrogen, phosphorus, and potassium levels and their levels in the Strawberry plant leaves. Also, a positive relation was reported between the soil organic matter and the level of manganese and phosphorus in leaves. Moreover, a significant negative correlation was demonstrated between the soil organic matter and the plant pH level. These correlations were confirmed by the principal component analysis (PCA) which demonstrated the presence of three principal components accounting for 54.42% of the total variations, reflecting the important proportions of the various patterns of mineral and organic traits among accessions. In PCA, the most discriminative traits were clustered in PC1 and PC2. These findings may highlight the specific mineral needs for the A. unedo plant for its optimal cultivation and subsequent domestication in Morocco.

“…Briefly, 100 g of the lyophilized powder is homogenized with 1,000 ml of distilled water under magnetic stirring at room temperature for 24 h. The extract was filtered through a Whatman No. 4 filter paper, lyophilized, and then stored in the dark at −20°C until use (Ait Lhaj et al, 2021b ).…”
