This paper evaluated the frequency, magnitude and dose/concentration range of hormesis in four species: The aquatic plant Lemna minor, the micro-alga Pseudokirchneriella subcapitata and the two terrestrial plants Tripleurospermum inodorum and Stellaria media exposed to nine herbicides and one fungicide and binary mixtures thereof. In total 687 dose-response curves were included in the database....

Aim: Stellaria media Linn. (Caryophyllaceae) has been traditionally used for a variety of ailments such as inflammation, asthma, blood diseases and in the treatment of mental tension. In the present investigation, various pharmacognostic standards of the plant have been generated so that authentic S. media could be explored for its traditional claims. Materials and Methods: Various parameters l...

The tribe Alsineae is a large monophyletic group in the family Caryophyllaceae especially found across Eurasia and Americas, but with center of diversity Mediterranean region. Several previous molecular phylogenetic studies have focused on delimitation genera tribes Caryophyllaceae, subfamily Alsinoideae or broader sense than now recognized.

A 50-yr study at Fairbanks, AK, was started in 1984 to determine soil seed longevity of 17 weed species. Seeds were buried in mesh bags 2and 15-cm deep and were recovered 0.7, 1.7, 2.7, 3.7, 4.7, 6.7, 9.7, 19.7, and 24.7 yr later. Viability was determined using germination and tetrazolium tests. By 24.7 yr after burial (YAB), no viable seeds were found for common hempnettle, flixweed, foxtail b...
