An instrument designed to indicate, record, and integrate radiant energy sensed by an Eppley thermopile is described. The output of the thermopile is amplified by a d-c. operational amplifier. The amplified output is connected to a meter or a recorder and totalized by an integrator. The output is calibrated in Ly min−1 and the sensitivity in the three recording modes is better than 0.02 Ly min−1.

General Appearance

The geology, physiography, general appearance, climate and weather, and history of exploration of Somerset I. are discussed briefly. The principal habitats and the areas visited are described. Data are presented on prevailing winter wind directions on Somerset I. and Boothia Pen., drawn from observations on residual snowbanks and plant growth. A few phenological data are presented, which supply further evidence that spring development at low arctic sites lags behind that at both subarctic and high arctic sites. Annotated lists are given of the fungi (28 species) and vascular plants (90 species) collected. Among the fungi Puccinia helicalis sp. nov. on Pedicularis capitata, and Doassansia nearctica sp. nov. on Ranunculus hyperboreus are described; and Exobasidium warmingii, intermediate between Exobasidium and Kordyana, is made the type of Arcticomyces gen. nov. Thirty-two species of vascular plants are added to the recorded flora of the island.

History Of

Benlate 50 DF has been implicated in causing long term damage to leatherleaf ferns. Damage to leatherleaf fern including frond distortion, discoloration and growth suppression continues to occur even after two or more years following last Benlate application. Electron micrographs of affected plants roots indicate a loss of root hairs and a proliferation of associated soil bacteria on the root surface compared to healthy plants. Plants with history of continued Benlate application have extensive bacterial colonies embedded on the root surface, but these colonies were not parasitic. Lcatherleaf fern plants which only had their rhizomes dipped in Benlate at planting lacked the embedded colonies, but were extensively covered with bacteria. Bioassays of bacteria taken from the rhizoplane and rhizosphere of the these leatherleaf ferns showed that these bacteria have the ability to produce growth regulators and/or toxins which may be detrimental to plant growth when absorbed through the root. Consequently, Benlate may be influencing fern growth indirectly by modifying bacteria composition of the growing media to favor proliferation of deleterious, non-parasitic bacteria.

Cotton Cultivar

The reniform nematode, Rotylenchulus reniformis (Linford and Oliveira), remains a common, widespread nematode pest of cotton across the southern United States. Trials were conducted during 2017 at three non-irrigated locations: one location in Hamilton, MS, and two locations in Tchula, MS, in field settings with a history of cotton production and documented economically-damaging reniform nematode populations. Trials were designed to evaluate the response of two cotton cultivars to in-furrow nematicides consisting of aldicarb, 1,3-dichloropropene, and a non-treated control applied for nematode suppression. No significant interactions between cotton cultivar and nematicide were observed. However, treatment with 1,3-dichloropropene produced greater plant biomass, and plant height compared to aldicarb-treated cotton and the nontreated. Nematode densities were suppressed with the use of 1,3-dichloropropene compared to aldicarb and the non-treated control. The use of 1,3-dichloropropene resulted in positive early-season plant growth responses; however, these responses did not translate into greater yield.

Plant Growth Stimulants

The review article addresses the potential use of brassinosteroids and synthetic brassinosteroid-based preparations to protect plants exposed to environmental lead contamination. Under climate change and anthropogenic chemical pollution of the biosphere, this stressor is one of the most important agents that reduce the yield and quality of crops, and, therefore, it deserves close attention. Brassinosteroids and brassinosteroid-based preparations are regarded as universal plant growth stimulants and adaptogens. To support this assertion, it is important to study behavior of brassinosteroids under environmental lead contamination and discuss arguments in favor of their preferential use. The article provides information about the history of discovery and study of brassinosteroids, reports data on their chemical nature, biosynthesis, metabolism, and mechanisms of action on the plant cell, and describes interactions of brassinosteroids with other substances that stimulate plant growth and development. The article discusses phytotoxicity of lead and its influence on the growth, development, productivity, and resistance of plants. Literature data and results obtained by the authors provide evidence of the protective effect of brassinosteroids and brassinosteroid-based preparations on plants exposed to lead contamination and suggest reasons for their preferential use in the context of chemical pollution. Arguments are offered in favor of further research of these biostimulants in order to specify their use depending on the characteristics of the stress factor and biological properties of the plant
