١ Physiology of carrot growth and development Introduction • Carrot (Daucus carota L. ssp. Sativus (Hoffm.) Schübl. & G. Martens) originates from the wild forms growing in Europe and southwestern Asia (Banga 1984). • The western type of cultivated carrot is thought to derive from the anthocyanin-containing forms found in Afghanistan. • The first cultivated carrot types were purple or violet; ye...

Range forage of Vicia variabilis, Astragalus spp., Medicago sativa, Prangos uloptera and Sanguisorba minor was sampled during three phenological stages from the controlled rangeland stations in Chaharmahal and Bakhtiari province, Iran. Samples were analyzed for the determination of Crude Protein (CP%), Ether Extract (EE), Crude Fiber (CF), total Ash, Neutral Detergent Fiber (NDF), Acid Detergen...

Polysomes were isolated from an enterotoxigenic strain of Clostridium perfringens during vegetative growth and at 1-h intervals after transfer into Duncan-Strong sporulation medium. During vegetative growth, about 67% of the ribosomes were in polysomal complexes. This proportion decreased to about 20% during the first 2 h in sporulation medium and then gradually increased to a maximum of 45% at...

Jagua (Genipa americana L.) is widely distributed throughout the Americas. It has been used since ancient times due to pigments extracted from its fruit. This study aimed evaluate vegetative growth of five accessions by adjusting non-linear models dasometric variables. The (Porce, Chigorodó, San Carlos, Luis, and Vigía del Fuerte in Antioquia) were collected central-western region Colombia. gro...

One of the main constraints in Aloe vera production is poor information about optimum nutrients that are helpful for growth and production. The objective of this study was to optimize nutrient solution for Aloe vera cultivation in soilless culture. Therefore, to determine the best nutrients the experiment was conducted in a greenhouse during 2011 in the Agricultural Faculty, University of Guila...
