quality are influenced by many factors, including climatic conditions and production practices. In subtropical climates, the temperature usually falls below 70°F for several months during winter. This period of cool temperatures causes growth to cease and citrus trees to become dormant for about three months. The cool temperatures during this dormant period promote floral induction. When warm s...

The colonial growth of Bacillus subtilis vegetative and spore cells was evaluated by determining the time course of the growth heat changes (growth thermogram) with a microbial calorimeter. The actual heat evolution curve (f (t) curve) obtained from the thermogram was in good agreement with the viable cell number changes. From the logarithmic f (t) curve, the exponential growth phase was estima...

Females of woody dioecious species usually devote more resources to reproduction than males. This may lead to a decrease in female survival and growth. The costs of reproduction, however, can be lightened through a number of mechanisms, as for example avoiding the temporal coincidence of reproduction and vegetative growth. The aim of this study was to evaluate whether males and females of P. le...

The relationshipbetween secondary metabolites content and antioxidant activity was studied in aerial parts of Nasturtium officinale R. Br., at various altitudes and periods of growth in north of Iran. Total phenolics (TP), and total flavonoids (TF) contentsin aerial parts of the plantwere investigated spectrophotometrically and their antioxidant activitieswere obtained byTotal Antioxidant Capac...

Streptomyces coelicolor produces spore-forming aerial hyphae after a period of vegetative growth. These aerial structures are decorated with a hydrophobic coating of rodlets consisting of chaplins and rodlins. Here, we show that rodlins and the surface-active peptide SapB are essential for development during growth in a medium with high osmolarity. To this end, both vegetative and aerial hyphae...

Induction of milk\disease in 50% of Japanese beetle (Popillia ;apmlica) !aIT,\(' 1)\· feeding requires about IQ1l spores of Bacilllls popilliae per gram of soil. The infectious process occurs in four phases: (1) An initial incubation phase of about :2 da~'s during which there is no evidence of infection in the hemoh-mph. (2) ,-\ \'egetative phase of poJiferation in the hemolymph which lasts unt...

Twenty five Sri Lankan modern rice cultivars were screened for submergence tolerance at seedling and vegetative stages. An experiment was carried out at the Faculty of Agriculture, University of Ruhuna, Mapalana, Kamburupitiya, Sri Lanka during May to September, 2011 according to the randomized complete block design (RCBD) with 4 replicates and each replicate contained 20 plants to evaluate sub...
