Abstract:
... Seventeen tea accessions belonging to Chinese (Camellia sinensis), Assamic (C. sinensis var. assamica), and Shan tea (C. sinensis var. pubilimba) groups, which are either commercially planted or new promising tea germplasm, were morphologically described at Phu Tho province (Viet Nam) and assessed for their diversity. Fourteen phyllometric parameters were qualitatively and quantitatively investiga ...

germplasm; terminology; landraces; farmers; agronomic traits; plant genetic resources; germplasm conservation; artificial selection; crops
Abstract:
... Farmers' seeds are most often lumped together in one broad category called 'landraces'. But such a category covers variety types that reflect different levels of farmer involvement. Those differences matters when we discuss such issues as genetic erosion, on-farm conservation and seed related policies. The term landrace can be traced to the time when 'modern' varieties of cereals were introduced t ...

Abstract:
... The Passiflora L. (Passifloraceae) genus consists of about 500 species widely distributed throughout tropical and subtropical regions, commonly known as the passion flower. The passion flowers are considered ornamental plants because of the exotic beauty of their flowers and variant foliage. Since their introduction to the Old World, around 1625, seventeenth century, they have been used to decorat ...
