“…These findings are in accordance with the earlier reports. Kopcewicz (1969Kopcewicz ( , 1970 and Kopcewicz and Rogozinska (1972) reported that estrone, estradiol and estriol stimulated elongation and sugar content by 30% in pea and pine seedlings. Dogra and Kaur (1994) reported that protein content was increased by estrone, testosterone and 17a-hydroxy progesterone in germinating wheat seeds as compared to control.…”

“…Meristem activity in the roots of Melandrium dioecium, Rumex acetosa and Anthoxanthum aristatum was accelerated by estrone and testosterone (Helmkamp and Bonner 1952). Similarly, MSH increased growth and sugar content in pea and pine seedlings (Kopcewicz 1969(Kopcewicz , 1970Kopcewicz and Rogozinska 1972), and the growth of winter wheat seedlings (Janeczko 2000). On the other hand, the studies describing the effects of these hormones on plant antioxidant system are limited number in literature according to our knowledge.…”

In the present study, it was aimed to investigate the influence of exogenous mammalian sex hormones (MSH) (progesterone, b-estradiol and androsterone) on the morphological (root and shoot growth) and biochemical parameters (protein and sugar content, antioxidant enzyme activities, and lipid peroxidation and H 2 O 2 levels) of chickpea (Cicer arietinum L.) plants growing under control conditions. The solutions of hormones prepared at different concentrations (10 -4 , 10 -6 , 10 -9 , 10 -12 and 10 -15 M) were sprayed once on the leaves of 7-day plants. The plants were harvested on 18 days after the hormone treatment. Although all of the hormones at the tested concentrations significantly increased plant growth, soluble protein and sugar contents, and antioxidant enzyme activities [superoxide dismutase (SOD), peroxidase (POX) and catalase (CAT)], they decreased H 2 O 2 content and lipid peroxidation level when compared with control plants. The activities of SOD, POX and CAT reached to the highest levels at 10 -6 M for progesterone, and 10 -9 M for b-estradiol and androsterone, which maximum growth, protein and sugar contents were determined. The same concentrations also resulted in the lowest levels for H 2 O 2 content and lipid peroxidation. It can be interpreted that the MSH improve plant growth and development by affecting some biochemical parameters including antioxidative system.

“…Cytokinin activity in bean was increased by E^ and Eg, but ABA activity was unaffected (Kopcewicz, 1972d). In the reverse experiments, kinetin increased and ABA decreased the oestrogen fraction from bean (Kopcewicz, 1972a) but IAA (Kopcewicz, 1972a) and GA (Kopcewicz, 1971a) had no effects.…”

“…В многочисленных биотестах растения подвергали обработке стероидными гормонами жи-вотных, которые оказывали физиологическое действие (Love, Love, 1945). Например, эстрогены вызывали деление клеток в зародышах гороха (Kopcewicz, Rogozinska, 1972;Jones, Roddick, 1977), а с помощью тестостерона удалось изменить пол у растений бешеного огурца (Ecballium elaterium L.) (Kopcewicz, 1971) и сосны обыкновенной (Pinus silvestris L.) (Kopcewicz et al, 1977). Однако животные гормоны приходилось использовать в слишком высоких концентрациях (порядка 0,1 %), и вряд ли можно было говорить о специфичности полученных результатов.…”

Protective Effect of Preparations Containing Brassinosteroids on Plants Exposed to Environmental Lead Contamination / a Review

The review article addresses the potential use of brassinosteroids and synthetic brassinosteroid-based preparations to protect plants exposed to environmental lead contamination. Under climate change and anthropogenic chemical pollution of the biosphere, this stressor is one of the most important agents that reduce the yield and quality of crops, and, therefore, it deserves close attention. Brassinosteroids and brassinosteroid-based preparations are regarded as universal plant growth stimulants and adaptogens. To support this assertion, it is important to study behavior of brassinosteroids under environmental lead contamination and discuss arguments in favor of their preferential use. The article provides information about the history of discovery and study of brassinosteroids, reports data on their chemical nature, biosynthesis, metabolism, and mechanisms of action on the plant cell, and describes interactions of brassinosteroids with other substances that stimulate plant growth and development. The article discusses phytotoxicity of lead and its influence on the growth, development, productivity, and resistance of plants. Literature data and results obtained by the authors provide evidence of the protective effect of brassinosteroids and brassinosteroid-based preparations on plants exposed to lead contamination and suggest reasons for their preferential use in the context of chemical pollution. Arguments are offered in favor of further research of these biostimulants in order to specify their use depending on the characteristics of the stress factor and biological properties of the plant
