Selection of highly decorative plants of the Belarus native flora resistant to chloride salinization for use in landscaping of the urban environment

[Open Access] [ru] Laboratory diagnostics of high-decorative native species of Belarus flora for resistance to chloride salinization was carried out. Nine taxa were selected as subjects of study based on ecological and botanical analysis of roadside vegetation areas with different salinization levels. In the course of research, the effect of sodium chloride various concentrations on the germination and morphogenesis of the study objects during germination on Petri dishes and on the nutrient medium under in vitro conditions was studied. The percentage of germinated seeds and growth rates were analyzed on day 4, 8, 14 after soaking the seeds in sodium chloride solutions of concentrations 5, 10, 20, 50 g/l. It was established that the most resistant to salinization were the Achillea millefolium, Centaurea jacea and Verbascum nigrum. For these taxa, the decrease in germination was not more than 15 % at the 14th day of experiment. The Betonica officinalis, Knautia arvensis and the Galium verum were the most sensitive to chloride salinization. Viscaria vulgaris, Anthemis tinctoria and Anthemis arvensis were medium resistant to salinization under experimental conditions. In most cases, the presence of sodium chloride at a concentration of 5 g/l reduced the average root length by 50—60 %. For the Viscaria vulgaris, this reduction did not exceed 30 %. No reliable differences were found in the shoot average length at salinization of 5 g/l in comparison with the control. In vitro culture can be a convenient tool for laboratory diagnostics of plant salinization resistance during germination.

5 au 11 juillet 2021

Monday was a big watering day. I removed several Lomelosia that had died and continued weeding the prairie and thinning out this plant, that I am still trying to identify...

Tuesday I removed Tulipa bulbs from a sand area and prepared it for my Mediterranean plants. Adam (aka Christian) doesn’t want the sand in one bed in the glasshouse so I’ll use it to extend my planting area - a win-win because I also have a place to put the soil I don’t want that is currently in the bed.

Wednesday Mme. worked with me to plant some seeds that Alejandro left with me. I hope they don’t fry. I’ll have to keep them at my house.

Mira and Martin arrived Monday. He brought me some seeds and a few Pelargonium cuttings from Amsterdam. They are in the utility room where it is bright and warm, to encourage them to root quickly. We celebrated Martin’s birthday Tuesday evening in Biot. Wednesday night we headed to Juan le Pins for dinner at a Thai restaurant which was delicious. They headed back to The Netherlands Thursday morning.

I had my second Phizer jab Wednesday afternoon and this time no soreness in the arm, just a big headache all day Thursday that was barely kept in check by paracetamol.

Friday Alejandro came by and we had a very good meeting with Mme and her son. We checked out the new prairie and tried to identify all the flowering plants. I’m going to continue to thin out the Reseda lutea which is too dense and I really don’t want it going to seed for next year. We planted the first few plants in the new sand bed by the serre.

James dropped off Charlotte, a student working with him, to work here for a bit and to do some drawings of the planting plan and density. After we did some work in the garden and Alejandro had a good chat with Adam, the three of us headed to a delicious sushi meal. My first sushi since leaving London. I’m so happy to have found a nice place for sushi, and not too far, just at baie des anges.

Saturday I chopped back the wisteria and did some work in the garden for a few hours. I’m now watering all the citrus and fig trees for around an hour each every weekend. Later that evening Lucien arrived from Paris and we ate a restaurant with a view of Port Valbonne.

Sunday was a lazy day. Lucien made a delicious lunch of fish with onions. At the end of the day we went up to the atilier to check on some plants and to show Lucien the amazing views from up there. We enjoyed apero in the garden then we had a light dinner of leftovers.
