Effects of biochar on pepperoncini (Capsicum annuum L cv. Stavros) germination and seedling growth in two soil types

摘要

In the present study a total of one hundred thirty two accession of indigenous vegetable (Atriplex hortensis L.) collected from fifteen different Trans-Himalayan geographical regions of Jammu and Kashmir, India, were morphologically characterized for 6 qualitative and 15 quantitative traits following descriptors developed by the National Bureau of Plant Genetic Resource (NBPGR), New Delhi, India, during the year 2014 - 2015. Multivariate analysis, principal component analysis (PCA), multidimensional scaling (MDS) and cluster analysis were performed using morphological traits to determine whether these populations are reliably similar or diverse. The first two principal components encompass more than 60% variation among population. The results of PCA and MDS analysis were comparable to the cluster analysis, which shows considerable phenotypic variation. Study of morphological characteristics of the accessions showed considerable variations which signify rich diversity within populations from different regions of cold desert.
