rosa hybrida l. is an important commercial cut flower. salicylic acid (sa) and calcium chloride (cacl2) act as endogenous signal molecules responsible for growth parameters in plants. the aim of this study was to evaluate the effects of preharvest sa and cacl2 treatments in extending the vase life of cut rose flowers. therefore, a factorial experiment based on completely randomized design with ...

LSD1 was defined as a negative regulator of plant cell death and basal disease resistance based on its null mutant phenotypes. We addressed the relationship between lsd1-mediated runaway cell death and signaling components required for systemic acquired resistance (SAR), namely salicylic acid (SA) accumulation and NIM1/NPR1. We present two important findings. First, SA accumulation and NIM1/NPR...

Salicylic acid (SA) is an endogenous plant growth regulator of phenolic nature that plays a key role in the regulation of plant growth, development, interaction with other organisms and in the responses to environmental stresses such as drought. An experiment was therefore, conducted to evaluation the influence of exogenous SA application on some traits of common bean under water stress conditi...

In the present study, effects of edible coatings using sodium alginate (SA) and sodium alginate in combination with ascorbic acid (AA) on the shelf-life extension of strawberries at 4±1°C was studied. A factorial experiment was performed based on a randomized complete block design with four replications. The treatments included control (distilled water), SA (1%, 2%, 3% w/v), SA in combination w...

We isolated a dominant gain-of-function Arabidopsis mutant, accelerated cell death 6 (acd6), with elevated defenses, patches of dead and enlarged cells, reduced stature, and increased resistance to Pseudomonas syringae. The acd6-conferred phenotypes are suppressed by removing a key signaling molecule, salicylic acid (SA), by using the nahG transgene, which encodes SA hydroxylase. This suppressi...

BACKGROUND Cationic polymers have been accepted as effective nonviral vectors for gene delivery with low immunogenicity unlike viral vectors. However, the lack of organ or cell specificity sometimes hampers their application and the modification of polymeric vectors has also shown successful improvements in achieving cell-specific targeting delivery and in promoting intracellular gene transfer ...

Despite general effect of salicylic-acid (SA) in improving plant growth andproductivity in saline conditions, there have not been unanimity about the bestconcentration. In this 2-yr field study the effect of different SA concentrations(0, 0.5, 1.0, 1.5 and 2.0 mM) was examined on growth, grain yield and yieldcomponents of barley under two non-saline (2 dS m-1) and saline (12 dS m-1)conditions. ...

Firstly, this paper researches on the scheme of amplitude weighting(AW) for smart antenna(SA) beamforming in linear array. With the proposed mathematical model in this paper, QPSK base-band AW is an effective method for linear SA to realize multi-user and multi-direction transmission, by which the perfect directional beam-forming can be realized with low complexity and low cost. Secondly, this ...

salicylic acid (sa) is part of a signaling pathway that is induced by a number of biotic and abiotic stresses. it has been recognized as an endogenous regulatory signal in plants. in order to study the effect of different concentrations of sa on germination, growth and some physiological parameters in chickpea (cicer arietinum l.) two genotypes (mcc414, mcc361) under drought stress conditions, ...
