It is a challenge to track vegetative growth over time and to re-identify a moving vegetation object between collection intervals. In this paper we propose a set of methods to re-identify a patch, a procedure which will provide insight into the growth patterns of the vegetation. After describing our model, we propose two methods for re-identification, a centroid approach based on distance, and ...

Vegetative propagule pressure may affect the establishment and structure of aquatic plant communities that are commonly dominated by plants capable of clonal growth. We experimentally constructed aquatic communities consisting of four submerged macrophytes (Hydrilla verticillata, Ceratophyllum demersum, Elodea nuttallii and Myriophyllum spicatum) with three levels of vegetative propagule pressu...

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...

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...
