to study the effect of urea application in safflower (carthamus tinctorius) and determination of effective traits on its yield, a factorial experiment based on randomized complete block design in three replications was conducted in tabriz, iran, during 2012. studied factors were urea rate levels as 100, 150 and 200 kg/ha and urea application times 100% in sowing time, 50% sowing time + 50% stem...

in order to study the effect of density and time of urea foliar application on oil yield and essences percentage of black cumin (nigella sativa l.) a field experiment was conducted at research station of faculty of agriculture, azad university of birjand in 1387 growing season. three urea foliar application times [1-control 2-at 8-10 leaves stage 3-at 10% flowering 4-100% flowering ] and three ...

Forty five years after its publication, Ernest Gutmann’s book, “The Denervated Muscle,” still stands as a landmark publication. It summarized the state of knowledge of the time and introduced much new research that was ongoing at the Institute of Physiology in Prague. At the time, the response of a muscle to denervation was viewed primarily through the lens of the neurotrophic theory. Advances ...

Responses by flowering plants to climate change are complex and only beginning to be understood. Through analyses of 10,295 herbarium specimens of Himalayan Rhododendron collected by plant hunters and botanists since 1884, we were able to separate these responses into significant components. We found a lack of directional change in mean flowering time over the past 45 y of rapid warming. Howeve...

Three cases of cutaneous leishmaniasis were treated orally with a mefloquine dose of 4.2 mg/kg/day for six days in the Teaching Hospital of the Faculdade de Medicina do Triângulo Mineiro, Uberaba, MG, Brazil. Three weeks later a new series was repeated. No patient was cured.

This study conducted in Kerala, evaluated the role of conservation tillage (zero (ZT), minimum (MT), and conventional (CT)) with five treatment combination potassium (12 kg/ha, 20 40 kg/ha) magnesium sulphate (60 kg/ha 80 on total DMP, physiology grain yield test variety Anaswara (cowpea). In pot culture study, application K: MgSO4, 10:80 resulted highest chlorophyll content. While higher a con...

†Background and Aims Ageing effects may be due to dysfunction leading to decreasing reproduction and survival with age. In plants, however, other (physiological) causes, associated with size for example, may also play a role. Iteroparous plants with genetically variable life spans can be helpful in unravelling these two aspects of changes associated with growing older. †Methods In a long-term e...

During the initial vegetative phase, the Arabidopsis shoot meristem produces leaves with associated lateral shoots at its flanks, while the later reproductive phase is characterized by the formation of flowers. The LEAFY gene is an important element of the transition from the vegetative to the reproductive phase, as LEAFY is both necessary and sufficient for the initiation of individual flowers...
