Potamogeton nodosus tubers produce floating-type instead of submersed-type leaves when exposed to 10(-5) molar synthetic abscisic acid. Abscisic acid-induced leaves have stomata on upper leaf surfaces and higher width/length ratios than controls. These effects are wholly or partially overcome by simultaneous exposure to abscisic acid combined with gibberellic acid, kinetin, or benzyladenine.

Two SOD-mimic active dimeric Cu(II) chlorido complexes of the compositions [Cu(2)(μ-HL(1))(4)Cl(2)]Cl(2) (1) and [Cu(2)(μ-HL(2))(2)(μ-Cl)(2)(HL(2))(2)Cl(2)] · 4H(2)O (2) involving the cosmetologically relevant cytokinin kinetin (N6-furfuryladenine, HL(1)) and its derivative N6-(5-methylfurfuryl)adenine (HL(2)) have been synthesized and characterized by elemental analysis, infrared, and electron...

Continuous production of healthy plantlets of Sapindus trifoliatus L. was achieved via somatic embryos from long term cultures of an embryogenic mass (EM). A highly embryogenic culture of S. trifoliatus L. was obtained by recurrent embryogenesis from somatic embryos cultured on Murashige and Skoog's (MS) medium supplemented with kinetin (2.3 microM) and benzyladenine (8.8 microM). The cultures ...

The effects of phytohormone Kinetin on cell density, photosynthetic pigments, antioxidant enzymes, and fatty acids composition the microalgae Tetraselmis suecica were investigated. T. was treated with different concentrations (0, 5, 10, 15, 20, 25 mg/L) at optimal growth conditions (salinity 28 g/L, temperature 25°C, 24 hr photoperiod). Results indicated an increase in density all treatments co...

A short treatment o f excised buckwheat cotyledons with a solution o f kinetin lead to an up to 9-fold stimulation o f anthocyanin biosynthesis, to an about 50 percent increase in the accum ula­ tion o f rutin, and to an about 30 percent increase, on the average, in the accumulation o f C-glycosylflavones in the treated material during its posttreatment incubation in the dark. When the treated ...

In this study, studies were conducted to optimize callus and suspension culture methods for in vitro mutation breeding purple orange carrots. Following this, the developed mutant lines subjected salt stress selection. The study determined optimal agar dose. first germination, 50% root-cotyledon formation genuine leaf carrot seedlings analyzed daily which was continued with 7g/L cotyledon hypoco...
