Abstract:
The aim of the experiment was to evaluate the use of effective micro-organisms (EM) as promoters of root development and germination of K. daigremontiana plants. The 3 experimental groups in cultivation were: 1) group without micro-organisms (CTRL), irrigated with water and previously fertilised substrate; 2) group with sugar cane molasses (ML) and fertilised substrate; 3) group with effective micro-organisms (EM) and fertilised substrate. The test showed a significant increase in the agronomic parameters analysed in plants treated with effective micro-organisms. In fact, all plants treated with (EM) showed a significant increase in plant height, number of leaves, vegetative and radical weight, number and weight of new shoots, leaf area. Also regarding the physiological analysis of plants there is a significant increase in the parameters analyzed in the thesis with effective micro-organisms. In particular, there was a significant increase in the chlorophyll content, in leaf net photosynthesis rate (Pn) and water use efficiency (WUE) and an equally significant reduction in transpiration (TR) and stomatological conductance (Gs). In the thesis treated with EM, the experiment also showed an increase in the percentage of seed germination and a significant reduction in the average germination time. Effective micro-organisms can be a valuable tool for grafting before planting new plants, for spraying and irrigation of crops, for reducing or eliminating completely the use of plant protection products against pathogens and diseases, during the storage of plant raw materials and to increase the biological activity of the soil.
