Science of The Total Environment, 1991 Abstract The effect of 64 priority pollutants on the growth of Lactuca sativa in nutrient solution was determined, and quantitative structure-activity relationships (QSARs) were established relating EC 50 values with octanol/water partition coefficients (log K ow ) of the test chemicals.

Phytotoxicity of ionic liquids
Chemosphere, 2019Ionic liquids (ILs) have been one of the most interesting chemical entities over the last two decades and have been investigated by numerous scientists all over the world. However, during IL research, it has been shown that these compounds present toxicity to both terrestrial and aquatic plants, among others.

A study on phytotoxicity of alantolactone
Chemico-Biological Interactions, 1971Abstract The phytotoxic action of alantolactone was evident by its inhibitory effects on seed germination, seedling growth, rate of respiration, and degradation of starch and proteins in mung beans (Phaseolus mungo L.). Some amino acids, bases of nucleic acids, and gibberellic acid partially alleviated the alantolactone-induced inhibition of the seed

Phytotoxic activity of kiwifruit leaves and isolation of a phytotoxic substance
Scientia Horticulturae, 2019Abstract When aged kiwifruit (Actinidia deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson) plants are replaced with young ones, the growth and productivity of the young plants were occasionally lower than expected. This symptom is typical of the replant problems reported in several fruit trees. Phytotoxic substances released from the plant are assumed

Preliminary field experiments with 3,4-dichloropropionanilide (propanil) indicated that methods of application had little effect on the activity of this herbicide. Growth of tomato (Lycopersicum esculentum Mill.) plants was reduced for about 7 days. Susceptible plants were killed in 3 to 7 days.

We studied zinc phytotoxicity with lettuce seedlings in solution culture. Zinc absorption in lettuce (Lactuca sativa L. cv. Climax) consisted of two distinct uptake phases; a slow uptake phase below 5 μM and a rapid uptake phase above 5 μM of solution Zn.

Phytotoxic lignans ofLeucophyllum frutescens
Natural Toxins, 1999Bioassay-guided fractionation of the hexane:ethyl acetate (1:1) extract of the leaves of Leucophyllum frutescens (Berl.) I.M.Johnst (Scrophulariaceae) led to the isolation of its phytotoxic constituents diayangambin (1), epiyangambin (2), diasesartemin (3) and epiashantin (4). Phytotoxicity was demonstrated as inhibition of seed germination of Agrostis
