Abiotske bolesti jagode

Jagoda kao kultivirana vrsta pokazuje izuzetnu osjetljivost na razne abiotske čimbenike u uzgoju, posebno na nedostatak biogenih elemenata, odnosno hranjiva (mikro i makroelementi), kao što su dušik, kalij, fosfor, bor, kalcij i dr. Stoga je u uzgoju jagode od velike važnosti pratiti stanje hranjivih elemenata u tlu i reagirati čim se primijete simptomi nedostataka ili viška istih. Najčešći simptomi nedostataka ovih hraniva na svim biljkama, pa tako i jagodama, su promjene boje lišća (žućenja ili kloroze, crvenilo, tamnjenje i dr.), kržljavost i deformacije biljaka te malformacije plodova. Navedeni simptomi često se mogu preklapati između pojedinih hranjivih elemenata, ali i sa simptomima parazitskih ili infektivnih bolesti, kao što su viroze i fitoplazmoze. Kloroze se kao simptom najčešće javljaju u slučaju nedostatka dušika, željeza, magnezija, mangana, molibdena i cinka, dok se simptomi deformacija javljaju uglavnom u slučaju nedostatka bora (na plodovima) i kalcija (na listovima).
Strawberry as a cultivated plant species shows exceptional sensitivity to various abiotic factors in cultivation, especially the deficiency of nutrient elements (micro and macroelements), such as nitrogen, potassium, phosphorus, boron, calcium, etc. Therefore, in the cultivation of strawberries is very important monitoring of nutrients in the soil and reacting as soon as symptoms of deficiency are noticed. The most common symptoms of deficiency of these nutrients in plants, including strawberries, are changes in color of leafs (yellowing or chlorosis, redness, darkening, etc.), deformation of plants and fruit malformations. Chlorosis as a symptom most often occurs in the case of deficiency of nitrogen, iron, magnesium, manganese, molybdenum and zinc, while the symptoms of deformationsoccur mainly in the case of deficiency of boron (on fruits) and deficiency of calcium (on leaves).
