matricaria chamomilla is a medicinal plant that is widely cultivated in salt affected soils. this investigation was undertaken to study the effect of nacl concentration on germination, and the physiological, biochemical and growth characteristics of chamomile. seed germination and growth were studied at five nacl concentration levels (0, 40, 80, 120 and 190 mm nacl concentration). increasing th...

Adaptive mutation is a process by which an organism under nonlethal selective pressure produces mutations that relieve the selective pressure (see reference 5 for a review). It is illustrated particularly well by Escherichia coli strain FC40, a strain bearing an F episome carrying a lac allele with a frameshift mutation that makes it phenotypically Lac . When FC40 is plated on lactose-minimal m...

Almtrae t -Numencal calculaUons are presented in which homogeneous nucleation and growth of M g O particles in a thermal plasma reactor is simulated. The physical environment revolves cont inuous cooling from very high temperatures The numerical model involves a solution of the aerosol general dynamic equation coupled to a gas phase chemical kinetics calculation for generauon of M g O monomers ...

Background: Light-emitting diodes (LEDs) are a promising technology that has enormous potential to improve irradiance efficiency and replace traditionally used horticultural lighting. Compared with traditional light sources (e.g., high-pressure sodium lamps metal halide lamps) in crop production, LEDs tends have long life, generate less heat waste providing the perfect spectrum for plant growth...

The main objective of this study was to develop a nondestructive method for monitoring cotton growth and N status using a digital camera. Digital images were taken of the cotton canopies between emergence and full bloom. The green and red values were extracted from the digital images and then used to calculate canopy cover. The values of canopy cover were closely correlated with the normalized ...

Abstract Okra ( Abelmoschus esculentus ) is the most commonly and popular vegetables. The application of inorganic fertilizer very important to increase productivity crop, but overuse can lead soil acidification that affect plant growth. purpose these study determine effectiveness combination rate organic toward okra growth yield performance. This was conducted in a greenhouse by using Randomiz...

This research was conducted to study of the essential oil content, some morphological parameters, crop evapotranspiration (ETc) and crop coefficient (Kc) of Summer Savory (Satureja hortensis L.) in the west of Iran (Khorramabad region) in 2017. Weighing Lysimeters (25 cm diameter and 30 cm height) were used to measure important morphological parameters, t...

the effects of plant growth promoting rhizobacteria (pgpr) on growth and physiological characteristics of seedlings corylus avellana were determined in a forest nursery. for this purpose, in a completely randomized design (crd) and four replicates, three putative bacteria, including pseudomonas putida, bacillus subtilis and enterobacter cloacae, as alone and mixed, were examined. the greatest h...

Growth performance, food efficiency and body composition of pikeperch (Sander lucioperca) were investigated with 1 or 2 g/kg L-carnitine added to the diet. Control diet did not contain L-carnitine. Two hundred pikeperch fingerlings (1.63 g, mean weight) were stocked in each 1 m3 concrete tank and fed equally 6 meals per day for 6 weeks. Higher increment in body weight (5.92 ± 0.37 g), the ...
