dc.description.abstractABSTRACT The present investigations entitled “Studies on propagation and production potential of Malaxis acuminata D Don.” were carried out in the experimental field of the Department of Forest Products, College of Forestry, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2018 & 2019. In propagation studies, the sprouting percentage was very high (>93%) in all type of propagules used i.e basal, middle and top part of rhizomes, whole rhizome and whole pseudobulbs. However, the plants produced from basal part of rhizome as well as whole rhizomes recorded maximum value for most of growth and yield parameters. In the experiment on impact of size of propagule on growth and yield parameters, significant variation was observed in growth and yield parameters. The size of propagule greatly influenced the growth and yield parameters and maximum value for almost all the parameters was obtained in both large size rhizomes and large size pseudobulbs. In experiment studies on impact of crop geometry on growth and yield, the results revealed that spacing of both type of propagules (rhizome and pseudobulbs) at different spacings affected plant growth and yield attributes. In rhizomes with the increase in growing space from 25 cm2 /plant to 100 cm2,, the value of all the growth & yield parameters increased (except sprouting percentage and number of leaves/plant) where as in pseudobulbs with the increase in growing space from 12.5 cm2/plant to 50 cm2 /plant the value for almost all the growth and yield parameter increased (except number of leaves/ plant). The growing space of 50 cm2 /plant (for pseudobulbs)and 100 cm2 /plant (for rhizomes) in both propagules was required for acquiring optimum yield. Four germplasms MA/SS (INGR-18043), MA/SH, MA/CH and MA/KW were evaluated under the present study for growth and yield parameters. The MA/SS SS (INGR-18043) germplasm performed much better in terms of most of growth and yield parameters in comparison to all other germplasms. The plants of MA/SS(INGR-18043) germplasms can be easily identified on the basis of colour of newly sprouted growth, floral bud, flowers and rhizomes.en_US
