Taro (ColocasiaesculentaL. Schott) is a perennial root crop that belongs to Araceace family. It is widely cultivated as a staple food in Africa, Asia and pacific Islands. Despite its importance, there is limited information on many aspects of the crop. In order to obtain data that can support improved and sustainable taro production, a field trial was conducted to study the effects of ...

The aim of investigation was to determine the effects of aspect (north and south) on some morphological [plant height (cm), number of stems per plant, main stem diameter (mm), number of leaves per main stem, petiole length (cm), leaflet length (cm), leaflet width (cm), leaf: stem ratio] and chemical [crude protein (%), crude cellulose (%), calcium (%), phosphorus (%), potassium (%) and magnesiu...

to select an appropriate medium for the growth of plant is one of the problems of most greenhouse owners in production of pot ornamentals. so, current research was conducted to evaluate effect of some available media in mixtured by perlite on the growth of pothos. study was based on a completely randomized design with 5 treatments, 8 measuring times and 6 replications in a fiberglass greenhouse...

• Five viticultural parameters have been proposed in the literature as particularly important for defining a balanced vine able to produce high quality grapes: 1) total leaf area/yield, 2) yield/pruning weight, 3) pruning weight/linear meter of canopy length, 4) total leaf area/linear meter of canopy length, and 5) leaf density (leaf layer number). For very high-quality production, 2 more varia...

BACKGROUND AND AIMS Despite long-held interest, knowledge on why leaf size varies widely among species is still incomplete. This study was conducted to assess whether abiotic factors, phylogenetic histories and multi-trait interactions act together to shape leaf size. METHODS Fifty-seven pairs of altitudinal vicariant species were selected in northern Spain, and leaf area and a number of func...
