in order to provide the data needed for the design of saffron processing equipment, physical properties of its flower were investigated. these properties included dimensions, mass, true and bulk densities, porosity, static and dynamic coefficients of friction, and terminal velocity as a function of moisture content. the average range of these properties for the three different parts of saff...

Objective: Chamomile is one of the commercial medicinal plants produced in Ethiopia. Besides, it is priority crop in national aromatic and medicinal plants research project in the country. As chamomile production affected by production techniques this activity was conducted to identify the effect of seed storage duration and seedling raising methods on its seedling establishmen...

Camellia japonica L. is an evergreen shrub whose cultivars are of great ornamental value. In autumn, after flower bud differentiation, dormancy is initiated. As in many other spring flowering woody ornamentals, winter low temperatures promote dormancy release of both flower and vegetative buds. However, warm spells during late autumn and winter can lead to unfulfilled chilling requirements lead...

Gamma-linoleic acid in the seed oil of evening primrose makes it nutritionally and pharmaceutically valuable. If evening primrose wants to be cultivated as an annual plant, sowing time is important. By the late sowing and depends to time most plants do not produce flower stem and stay in rosette stage until next spring. To solve this problem, the present study was performed. Seedling were trans...

The capacity to form flower buds in thin-layer explants was studied in flowering plants of several species, cultivars, and lines of Nicotiana differing in their response to photoperiod. This capacity was found in all biotypes examined and could extend into sepals and corolla. It varied greatly, depending on genotype, source tissue and its developmental stage, and composition of the culture medi...

Monogenic inheritance and linkage among four morphological traits of lentil were established on the basis of F1 observations and analysis of 204 F2 plants in a cross for development of pubescence on peduncle, 228 F2 plants in a cross for tendril formation, 574 F2 plants in 5 crosses for flower numbers per peduncle and 464 F2 plants in 4 crosses for flower color under field conditions. Developme...

salvia genus belongs to lamiaceae family that was used in ancient and its application in culinary, flavor cosmetics, food and drinking industries is important. in the present study to assess compatibility of salvia sclarea to field condition and determine its potential for medicinal and ornamental applications, wild seed were cultured in pots. after initial growth, seedlings at 6-8 leaf stage t...
