Abstract
The present study entitled “Studies on propagation and evaluation of Murraya koenigii (L.) Spreng from Himachal Pradesh” was carried out during 2021-2023 in the experimental farm and laboratory of Department of Forest Products, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (Himachal Pradesh). “Morphological studies of Murraya koenigii L. Spreng” revealed that the plant was found to be a shrub, the stem was found to be erect, with numerous dots scattered around it. Leaves were found to be exstipulate, bipinnately compound, thin, ovate, serrate and shiny. Inflorescence was terminal cyme carries 50-80 flowers, flower was pale yellow green, petals were liner-oblong and dotted, 10 stamens were present in which filament was dilated at the base and ovary was 2-celled with single ovule. Effect of different pre-treatments on seed germination and growth parameters of Murraya koenigii (L.) Spreng exhibited significant effect and treatment T5 (GA3 800ppm) excelled in all germination and growth parameters viz., germination percentage (90.00%), early initiation of germination (9.33 days), completion the germination (19.00 days), maximum peak value (5.66), maximum mean daily germination (4.74 %), maximum germination value (26.84), maximum seedling shoot length (18.23 cm) and maximum root length (19.13 cm). With respect to the effect of different growing media on seed germination and growth parameters of Murraya koenigii (L.) Spreng growing media of soil + sand + vermicompost (1:1:1) resulted in the maximum germination percentage (86.66 %), early initiation of germination (10.00 day), early completion of germination (20.33 days), maximum peak value (6.35), maximum mean daily germination (4.26 %), maximum germination value (27.15), maximum seedling shoot length (17.60 cm) and maximum root length (18.90 cm). With regard to phytochemical analysis of Murraya koenigii L. Spreng leaves collected from different sites of Himachal Pradesh. The maximum total chlorophyll content (1.44 mg/g), maximum phenolic content (417.07± 0.92 GAE/g of crude extract) and maximum flavonoid content (324. 38 ± 1.39 RE/g of crude extract) was found in samples collected from Jhaniari (Hamirpur). The analysis also showed presence of alkaloids and absence of saponins among all the sites.
