Triticum aestivum L

Some Features of Implementation of Source-Sink Relations in Violation of the Integrity of the Root System of Seedlings of Triticum aestivum L.

Authors: Shevlyagina О. F., Korobko V. V.

The object of the study was sprouts of spring soft wheat Triticum aestivum L. Cultivation was carried out in a climatic chamber at a temperature of 18 ± 1°C under the conditions of a sixteen-hour photoperiod and complete etiolation. The experiment was carried out in the following options: removed the main germinal root; decapitation; removed the lower tier of germinal roots. Removing part of the root system of plants cultivated under a sixteen-hour photoperiod increases the root index and reduces the total length of the root system.

The Phytotesting of (thio)semicarbazones 2,4-diarylbicyclo[3.3.1]non-2-en-9-ones

Biological testing of (thio) semicarbazones 2,4-diarylbicyclo [3.3.1] non2-en-9-ones, differing in the nature of aryl substituents and nucleophile, was carried out.The object of the study was seedlings of spring soft wheat Triticum aestivum L. of the Saratovskaya 36 variety. To assess the physiological activity of the tested compounds, we used a valuable analysis of the morphometric parameters of growth of the root system and shoots of the test and control plants and the quantitative content of chlorophyll a, chlorophyll b, and carotenoids in the first leaf.
