Abstract
ABSTRACT The present investigation entitled: “Studies on reproductive biology and yield assessment of Echinacea purpurea (L.) Moench under midhill conditions” was carried out at the experimental farm of Department of Forest Products, Dr Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh, during the years 2015 and 2016. In the first experiment “Morphological studies” revealed the plants to perennial herb producing ovate to ovate lanceolate leaves and flowering shoots bearing capitula. Capitula were with neutral rays and bisexual disc florets. Roots were fibrous and mostly rhizomatous. In the second experiment “Phenological studies” revealed flowering duration during March to September with peak in June-July. After final seed setting, the plants undergo senescence becoming underground throughout the winter season. In the third experiment “Pollination studies” revealed the species to be allogamous with complete failure of autogamy. In the fourth experiment “Meiotic studies” revealed the species to be depend with 2n=22 chromosome with normal meiosis. In the fifth experiment “Effect of plant density and fertilizer doses on growth and yield” revealed maximum plant height, aerial biomass, number of floral heads and root biomass in twelve months after transplantation and best combination S3F1 with 15.00 g of dry root yield per plant.
