Differentiated leaf cells of gramineous plants, among them the cereals with their immense importance for human nutrition, are considered extremely recalcitrant to, if not incapable of, reentering the cell cycle. This recalcitrance is related to the poor wound response of the monocots-in contrast to most dicots-and the difficulties encountered in monocot tissue culture. We report here the highly...

Background Under field conditions, the development of crops depends on capacity of the canopy to intercept incident radiation and convert it into new biomass (Gifford et al. 1984). The amount of incident radiation intercepted depends on the leaf area index (LAI) and canopy orientation in space. The fraction of the incident photosynthetically active radiation (IPAR) that is absorbed by a canopy ...

The sandculture experiment with chloride as a variable has provided an excellent opportunity for detailed examination of the effects of excessive chloride on bearing avocado trees. Hass avocado trees have been under chloride treatment for the past four years. A summary of the more practical considerations of investigation such as leaf symptoms, mineral nutrition, growth and fruit characteristic...

The application of nutrient solutions to the foliage plants is an alternative means fertilise crops. Foliar fertilisation used overcome disadvantages soil applications. Variable plant responses these foliar spray have often been described in literature. However, knowledge about penetration mechanisms, role a leaf-applied inorganic or organic solution, and results obtained by its still limited. ...

A field experiment was conducted during growing seasons of 2014–15 and 2015–16 at College Agriculture Farm, University Agricultural Sciences, Raichur, Karnataka, to study the effect nutrient management on cotton (Gossypium Hirsutum L.) productivity leaf reddening for targeted yield medium deep black soil under irrigation. Three targets (3, 4 5 t kapas yield/ha)-based site-specific (SSNM) along ...

The rapid, accurate measurement of area in biological materials of varying colors, textures, and shapes is of special concern to the plant scientist. The need for the measurement of leaf area, in particular, has prompted the search for newer and faster methods in recent years. In general, leaf area is an excellent indicator of the photosynthetic capacity of a plant and the measurement of such a...

A field experiment was conducted to study the effects of N fertilization on uptake,accumulation/remobilization, use efficiency and yield of sunflower grown in alluvial plains ofnorthwestern India comprising four hybrids (PSH 996, PAC 3789, PSH 569 and SH 3322)and five N levels (Control, 40, 80, 100 and 120 kg N ha-1) in split-plot design with threereplications. Increased N fertilizer rates sign...

A declining Picea abies (L.) Karst. stand produced as much foliage and branches as a healthy stand but less stemwood at a similar leaf area index and climate. Nutrient analyses revealed that most biomass components at the declining site had lower concentrations of calcium and magnesium, but similar nitrogen and potassium (except for lower potassium in younger needles) and higher phosphorus , ma...
