In an earlier s tudy 1, 2 of leucine metabolism in crude heart extracts, da ta were obtained indicating that fl-methylcrotonyl CoA is acted upon by enoyl hydrase (crotonase) and tha t the resulting fl-hydroxyisovaleryl CoA is carboxylated enzymically in the presence of ATP to yield fl-hydroxy-fl-methylglutaryl CoA. This product is known 8 to be a t tacked by a specific cleavage enzyme to finnis...

Wheat growth in response to soil water deficit play an important role in yield stability. A field experiment was conducted for winter wheat (Triticum aestivum L.) during the period of 2002–2005 to evaluate the effects of limited irrigation on winter wheat growth. 80%, 70%, 60%, 50% and 40% of field capacity was applied at different stages of crop growth. Photosynthetic characteristics of winter...

soil compaction reduces growth of secondary roots, soil aeration and water and mineral uptake by plant, and decreases chlorophyll content as well as root yield and sugar content. hence, the effect of soil compaction on sugar beet yield and sugar content farms determined by penetrometer using 40 plots of 100 m2 in 40 sugar beet field of hamedan, asadabad, malayer and bahar at the depth of 0-80 c...

effects of plant density and harvest time on various two ecotype and one variety of chicory was examined at qazvin sugar factory research station in 2012. three genotype of chicory (two ecotypes of zanjan and kashan and one denveloped variety named orchis) with three plant densities (6, 12, and 18 plants/m2) and three harvest dates (31 august and 20 september and 11 october) were considered usi...

In a 3-year experiment (2002-2004), five N rates (0, 60, 120, 180, 240 kg N ha-1) were applied to sugar beets arranged in a Randomized Complete Block design with six replications. Experimentation took place under the semi-arid, irrigated conditions of central Greece. The aim of this work was to study the late season response of sugar beet crop to N fertilization as assessed by non-destructive m...

One method of effecting economies in product ion testing of da i ry cattle involves increasing the in terval between tests. Several studies have been published concerning the amount and importance of the accuracy lost when this in terval is lengthened. A t least seven investigators have repor ted the accuracy of lactat ion records computed f rom monthly bu t t e r fa t tests and milk weights as...

Chicory (Cichoriumintybus L.) is an important industrial crop which is used for inulin production. Inulin is widely applied as food ingredient due to its health promoting properties. For the first time, attempts were made to investigate thirteen endemic chicory genotypes including three pumilum populations, along with five root chicory cultivars, four witloof chicory varieties and a crispum end...

water and soil salinity in some regions of isfahan, east azerbaijan, and west azerbaijan provinces and also other parts of the iran are the main hindrance for crop planting. seeds of the tolerant crops to salinity such as cotton and sugar beet may have optimal germination and give acceptable performance if they become far from salt accumulation areas. to evaluate the effects of different planti...
