Standard Composition

The Wrocław version of hydroponic culture was applied. The content of particular microelements (Cu, B, Mn, Mo, Zn) or several of them jointly was increased ten times (to 6 mg/l) as compared to the standard composition of the nutrient solution. It was found that the yield of fruits and of capsaicin per plant was significantly higher with 10 times increased content of Cu and B or Cu+B+Mo or Cu+Mn+Mo or B+Mn+Mo. Moreover, Cu and Mn applied alone or in combinations with other microelements in 10-fold increased proportion caused a marked increase of capsaicin content in the dry matter of the fruit. It is suggested that the proportions of microelements should be chosen individually for each plant species and for each type of agroclimatic conditions

Capsicum annuum L. belongs to the Solanaceae family and is a species of huge economic importance and high nutritional value. A study conducted in the years 2014–2015 at the Department of Horticulture, West Pomeranian University of Technology in Szczecin, assessed the content of macro- and micronutrients in the fruit of selected Polish and Bulgarian cultivars of pepper collected at different stages of coloration development. The investigation included five Polish cultivars: Roberta, Marta Polka, Etiuda, Trapez and Cyklon and five Bulgarian cultivars: Bulgarski Ratung, Sivriya, Kurtovska Kapiya, Delikates and Dzuliunska Shipka. The study demonstrated a significant effect of cultivar and a degree of fruit coloration on the content of dry matter and macro- and micronutrients. The coloured fruits featured higher content of dry matter than the green ones and cv. Etiuda had the greatest dry matter. Green fruits contained more Mg, Mn and Zn, while the coloured ones more Ca and Fe. Cvs. Delikates and Dzuliunska Shipka were particularly rich in Mg and K, cv. Sivriya in Ca and cv. Etiuda in P, Cu, Zn and Mn were the most abundant in cv. Delikates, Fe in cv. Trapez, and Na in cv. Cyklon.

Growth Regulator Treatment

The Wrocław version of hydroponic culture was applied. Under optimal conditions of root fertilization the plants were sprayed with growth regulators sueh as gibberellins, auxins and kinetins, and .their mixtures. Each growth regulator treatment was applied with or without NPK added. The influence of these treatments on the fresh and dry weight of the fruit, percentage of ripe fruits and content and yield of capsaicin was studied. The highest yield of fruits and capsaicin. was obtained from plants sprayed with gibberellic acid and kinetin (in concentrations of 10 and 5 mg/l, respectively) together with NPK foliar application. No influence of ,growth regulators and foliar-applied NPK was noted on capsaicin content and dry weight of fruits.
