| dc.description.abstract | The effect of different green shade net houses on the growth and biochemical constituents were recorded during the present investigation on four different Ocimum spp. (O. tenuiflorum, O. sanctum, O. basilicum and O. gratissimum). The plants were grown under five different shading intensities viz- 35%, 50%, 75%, 90% and open (no net condition) as control. Growth parameters like number of branches, number of leaves, total fresh weight, total dry weight, leaf dry weight, shoot dry weight were recorded to be higher in 35% shading intensity than control and other shading intensities whereas stem diameter and root length were higher in control in comparison to other shading intensities. However, parameters like plant height, internodal length and leaf area were recorded higher in 90% shading intensity than in control. All growth parameters except plant height, internodal length and leaf area were found to be suppressed as the shading intensity was increased beyond 50%. The requirement of moderate light intensity for better growth and development has been reflected in maximum growth parameters. Variable response was observed for biochemical parameters in different shading intensities. However, the trend was same for all species. Biochemical parameters like total carotenoid content, total sugars, reducing and soluble protein were recorded maximum in control i.e. under full sunlight followed closely by 35% shading intensity while 90% shading intensity recorded highest chlorophyll a, chlorophyll b and total chlorophyll content. Total phenols and flavonoids were recorded to be highest in control (no net conditions) followed closely by 35% shading intensity while alkaloids and terpenoids were recorded to be highest in 35% shading intensity followed closely by control. However, biochemical parameters were influenced but phytochemical compounds like alkaloids and terpenoids recorded increase under 35% shading intensity which contribute to its medicinal properties. Therefore, in present investigation, Ocimum spp. performs better in 35% shading intensity than other shading intensities and control. | en_US |
