Journal ArticleDOI
Identification of nutrient deficiency in maize and tomato plants by in vivo chlorophyll a fluorescence measurements.
Hazem M. Kalaji,Abdallah Oukarroum,Vladimir Alexandrov,Margarita Kouzmanova,Marian Brestic,Marek Zivcak,Izabela A. Samborska,Magdalena D. Cetner,Suleyman I. Allakhverdiev,Vasilij Goltsev +9 more
TL;DR: Results indicate that some of presented fluorescence parameters could be used as fluorescence phenotype markers in order to identify/predict the nutrient deficiency using the fast chlorophyll fluorescence records.
Journal ArticleDOI
Drought-induced modifications of photosynthetic electron transport in intact leaves: Analysis and use of neural networks as a tool for a rapid non-invasive estimation
Vasilij Goltsev,Ivelina Zaharieva,Petko Chernev,Margarita Kouzmanova,Hazem M. Kalaji,I. Yordanov,Vassilena Krasteva,Vladimir Alexandrov,Detelin Stefanov,Suleyman I. Allakhverdiev,Reto J. Strasser +10 more
TL;DR: This work uses simultaneously recorded signals of photoinduced prompt fluorescence and delayed fluorescence as well as modulated reflection of light at 820nm for analysis of the changes in the photosynthetic activity in detached bean leaves during drying to demonstrate that this is a reliable method for determination of RWC in detached leaves.
Artificial neural networks and their application in biological and agricultural research
TL;DR: It is shown that data analysis using artificial neural networks (ANNs) has been increasingly applied worldwide in a range of scientific fields, including biological and agricultural research, and has become an attractive alternative to accepted statistical methods.
Journal ArticleDOI
Optimal Nitrogen Supply Ameliorates the Performance of Wheat Seedlings under Osmotic Stress in Genotype-Specific Manner.
T. Kartseva,Anelia G. Dobrikova,Konstantina Kocheva,Vladimir Alexandrov,Georgi Nikolov Georgiev,Marian Brestic,Svetlana Misheva +6 more
TL;DR: In this paper, the authors evaluated the performance of two contrasting wheat genotypes (old Slomer and modern semi-dwarf Enola) at the seedling stage to assess how N supply affected osmotic stress tolerance and capacity of plants to survive drought periods.
Journal ArticleDOI
Do Protected Areas influence populations of the threatened red alga Phyllophora crispa along the southwestern coast of Crimea (the Black Sea)?
TL;DR: In this paper , the authors compared the status of P. crispa populations in the southwestern coast of Crimea at present and before the MPA establishment, and assessed their current state in the marine protected and unprotected areas.
