Abstract
U radu su istraživane promjene morfo-anatomskih obilježja male vodene leće (Lemna minor L.) izložene natrijevom kloridu (50, 100 i 150 mM NaCl) i sintetskom citokininu 6-benzilaminopurinu (1x10-3 mM 6-BAP), pojedinačno i u kombinaciji. Povišeni salinitet uzrokovao je smanjenje opsega i površine fronda, stipe-a i korijena te progresivno nakupljanja škrobnih zrnaca u mezofilu (100 i 150 mM) i korijenu (150 mM). 6- benzilaminopurin stimulativno je djelovao na rast fronda i duljinu stipe-a, ali nisu utvrđene promjene u anatomskoj građi. Kombinacija solnih tretmana i citokinina utjecala je na povećanje opsega i površine stipeova i korijenja, u odnosu na solne tretmane. Škrobna zrnca detektirana su u korijenu pri najnižoj koncentraciji soli. U frondu i stipe-u utvrđeno je progresivno nakupljanje škrobnih zrnaca pri višim koncentracijama soli (100 i 150 mM NaCl + 6-BAP). Rezultati istraživanja pružili su detaljan uvid u morfo-anatomsku građu male vodene leće i promjene uzrokovane djelovanjem kombinacije citokininskog fitohormona i povišenog saliniteta, čime značajno doprinose fundamentalnoj znanosti.
Abstract (english)
The paper investigates changes in morpho-anatomical characteristics of common duckweed (Lemna minor L.) exposed to sodium chloride (50, 100, and 150 mM) and synthetic cytokine 6-benzylaminopurine (1x10-3 mM), individually and in combination. Increased salinity caused a decrease in the perimeter and surface area of the frond, stipe, and root and a progressive accumulation of starch grains in the mesophile layer (at 100 and 150 mM) and roots (at 150 mM). 6-benzylaminopurine stimulated the increase in frond and stipe size and length without visible changes in anatomical structure. The combination of all salt treatments with phytohormone increased both stipe and root's perimeter and surface area. At the same time, starch granules were detected in roots only in the lowest salt treatment (50 mM NaCl + 6-BAP). Progressive accumulation of starch grains at higher salt concentrations (100 and 150 mM NaCl + 6-BAP) was found in fronds and stipe. The research results provided a detailed insight into the morpho-anatomical structure of the common duckweed and changes caused by a combination of cytokinin phytohormone and increased salinity, thus significantly contributing to fundamental science
