Automatic Accessment of Phenotypes in lettuce plants by using Chlorophyl Fluorescence Kinetics and Machine Learning
Agriculture aims at increasing production and provision of high quality products to the market. Most of the times, quality is strongly correlated the variety or the hybrid. Specifically, lettuce qualitative characteristics and nutrients appear to vary strongly in different varieties and hybrids. In the current research, lettuce plants were harvested at baby, immature and mature stage in 46, 60 ...
متن کاملCationic chlorophyl derivatives with SOD mimicking activity suppress the proliferation of human ovarian cancer cells.
Derivatives of chlorophyl, e.g. Fe-chlorin e6-Na, alpha, beta, gamma, delta-Tetraphenylporphine-tetrasulfonic acid disulfonic acid salt tetrahydrate (Fe-TPPTS) and alpha, beta, gamma, delta-Tetrakis (4-N-trimethylaminophenyl) porphine, tetra (p-toluensulfonate (Fe-TTMAPP), express SOD mimicking activity. Examination was made of suppressive effects of human cancer cell lines by derivatives of ch...
متن کاملSignals regarding the Isolation of Chlorophyl-free Algae in the Milk of Some Healthy Cows and Some with Mamittis
In the microbiological investigation, made on samples of normal; (n=412) and mastitic (n=482) milk, proceeded from eight dairy cows farm, in Transilvania, it was signal the presence of the algae without chlorophyl belonging to Prototheca, forming together with bacteria and fungi the micro flora of the mammary gland. The alga content of normal milk was signaled only in two farms (2.27%, respecti...
متن کاملEffect of Phosphorus Fertilizer Rate on Seedcotton Yield and Petiole Phosphorus Concentrations
monly used instruments is a Minolta SPAD (soil plant analysis development) meter. The SPAD meter measures the difference in light absorption at 430 and 750 nm (Wood et al., 1992). The former is the transmittance peak for chlorophyl ‘a’ and ‘b’, and the latter is in the near-infrared region. The instrument converts the difference in light absorption at these two wavelengths into a numerical SPAD...
