Foliar analysis by direct‐reading vacuum emission spectrometry

Journal of the Science of Food and Agriculture, 1975
AbstractA method is described for the determination of calcium, magnesium, phosphorus, sodium, inorganic sulphur, boron, manganese and zinc in leaves by direct‐reading vacuum‐emission spectrometry. The ashed samples are diluted with graphite and cellulose.

Foliar microstructure and histochemical analysis of the lavender tree (Heteropyxis natalensis Harv.)

Micron, 2022
Heteropyxis natalensis Harv. is a native South African tree used in traditional medicine among Venda and Zulu communities. In this study, micromorphological investigations using light and scanning electron microscopy identified long, tapered non-glandular trichomes on the abaxial and adaxial surfaces of the leaves.

Genetic stability analysis using DNA barcoding and molecular markers and foliar micro-morphological analysis of in vitro regenerated and in vivo grown plants of Artemisia vulgaris L.

, 2020
The current study provides an enhanced and reproducible micropropagation system in Artemisia vulgaris L. using nodal explants of mature plants. The explants were cultured on basal Murashige and Skoog’s (MS) medium augmented with 6-benzylaminopurine (BAP)

Risk assessment and biophysiochemical responses of spinach to foliar application of lead oxide nanoparticles: A multivariate analysis.

Chemosphere, 2019
Despite extensive research progress in the recent past, the data regarding foliar uptake of heavy metals, associated biophysiochemical changes inside plants and possible health hazards are limited.

Using Foliar Analysis to Classify Nitrogen‐Deficient Sites

Soil Science Society of America Journal, 1984
Abstract Discriminant analysis was used to evaluate the efficacy of using foliage N concentration (FN), an adjustment of the foliage N concentration based on stand age (FA), and a nitrogen/phosphorus ratio (N/P) to classify N‐deficient sites. N/P was the superior index of N deficiency.

Foliar Analysis of Tea

Experimental Agriculture, 1970
SUMMARYThe literature for the past seventy years describes a variety of methods of sampling tea leaves, in some of which analytical data from samples have been suggested as capable of widespread use as a measure of the nutritional status of tea plantations.

Foliar Analysis as a Diagnostic Technique in Tropical Horticulture

1984
A brief history of the development of foliar analysis as a diagnostic technique for horticultural crops is reviewed and discussed. Terminology, together with a basic discussion of the components necessary to operate a successful foliar analysis program for growers, is presented.

Foliar analysis using near infrared reflectance spectroscopy

Canadian Journal of Forest Research, 1988
Near infrared reflectance spectroscopy was evaluated as a method for measuring nitrogen and lignin content in foliage of native forest and prairie species. Near infrared reflectance spectra (1590 to 2357 nm) were obtained for 163 samples of dried green leaves and leaf litter from 18 deciduous and 2 coniferous tree species.

Nutrient-limited conditions determine the responses of foliar nitrogen and phosphorus stoichiometry to nitrogen addition: A global meta-analysis.

Environmental Pollution, 2018
To test the hypothesis that nutrient-limited conditions can determine the responses of nitrogen (N) and phosphorus (P) stoichiometry to N addition, a meta-analysis was conducted to identify the different responses of foliar N and P concentrations and N ...
