Celem pracy było porównanie reakcji 3 gatunków roślin na różne stężenia cynku. W kulturach wodnych testowano siewki grochu zwyczajnego (Pisum sativum L.) odm. Iłówiecki, gorczycy białej (Sinapis alba L.) odm. Borowska i słonecznika zwyczajnego (Helianthus annuus L.). Cynk wprowadzano w postaci ZnS04 x 7H20 w stężeniach: 0, 10, 40 mg x dm-3. Określano tempo wzrostu systemu korzeniowego w kilku terminach...
Shoots of pea cv. ‘Cukrowy Iłówiecki’ were studied after 3-weeks hydroponieal culturing. There were applied four aluminium levels: 0, 3, 6, 27 mg Al/dm³ of medium Shoot height, stem diameter, leaf surface area and their tissues were compared. The light as well as scanning electron microscopies were applied. The aluminium stress (27 mg Al/dm³) caused the significant decrease of stem height and diameter...
Roots of pea cv. “Cukrowy Iłówiecki” were studied in water cultures using AlCl₃ in following doses: 0, 3, 6, 27 mg Al/dm³ medium (3-weeks course) as well as 0, 6, 27 g Al/dm³ medium (1-week course). Root length measurements were carried out in several terms. There were compared the anatomical structures of top and proximal root zones in a light microscope. The surface of a cap and epidermis were investigated...
