A Treatise on the Improved Culture of the Strawberry, Raspberry, Gooseberry, and Currant : In Which are Pointed Out the Best Methods of Obtaining Ample Crops of These Fruits, to Which are Prefixed Descriptions of the Most Esteemed Varieties
Full text linkPREFACEThe following instructions for an improved method of cultivating the STRAWBERRY, RASPBERRY, GOOSEBERRY, and CURRANT, are respectfully submitted to those who desire to obtain these fruits of a large size and of an excellent flavour ; and in full confidence that, where a due regard is paid to the directions laid down, the reward will be ample crops of superior fruit. The STRAWBERRY is a native if woods and shady situations, and consequently ought not to be planted indiscriminately in any place. The object in these pages has been to point out and recommend a method by which its culture may produce, with the utmost certainty, large crops of superlatively fine fruit in the driest seasons. The RASPBERRY is (although it is not generally known) a bog soil plant, or naturally a plant of shade ; the original red sort growing wild in woods, where the soil is cool and soft, as ·in the north of England: it also succeeds beyond conception on fenny and boggy soils, even contiguous to very large bodies of standing water. In suck situations, both wood and fruit will generally prove doubly large and prolific in the extreme; whereas, when it is planted on hot and dry soils it produces inferior and small sized fruit. By the. cultivation here laid down for the GOOSEBERRY, the fruit of several varieties may be obtained, in far greater perfection, beyond in size and flavour, than by any preceding practice ; and an easy and certain method of preserving this fruit in full perfection, beyond the common season of maturity, is also pointed out. A novel system, of propagating; the several sorts, by planting cuttings take in from bearing trees when their fruit is full ripe, is also here described, by which much time will be saved, and the particular variety will certainty be obtained. It is now well known that the very same sort of Gooseberry, by being planted in different soils and by different management, has produced very different sized fruit the annual exhibitions of this fruit by our Horticulturists constantly exemplify this. Of the CURRANT it is not necessary to say more, than that the best methods of obtaining the finest fruit are here described. It is scarcely necessary to make any observations on the Plates which accompany the work; they are correct transcripts of nature, and, as such, contribute of course to the value and importance of this compendium.https://openprairie.sdstate.edu/archives_rare-books/1014/thumbnail.jp
Biology and Ecology of Sickleweed (Falcaria vulgaris) in the Fort Pierre National Grassland of South Dakota
No full textIn the last two decades the exotic plant sickleweed (Falcaria vulgaris Bemh., Apiaceae) has invaded, and come to dominate, large areas of the Fort Pierre National Grassland (FPNG) in central South Dakota, USA. Currently sickleweed is estimated to infest over 3200 ha of FPNG. The purpose of this study was to examine several of the biological and ecological traits that may contribute to the invasiveness of sickleweed in FPNG. Specifically, I researched germination characteristics of sickleweed seed collected from FPNG, the effect of sickleweed on other grassland vegetation in FPNG, and vegetative reproduction and regeneration of sickleweed from roots. Germination trials conducted at the SDSU Seed Testing Laboratory found that sickleweed seed had a high degree of germination (70-90%) in all tested conditions. Germination response was higher at cooler temperatures with no effect of light conditions or storage temperature (at P,:S0.05 level). Germination was significantly lower (at P,:S0.05 level) after 18 months of storage. In simulated field conditions with soil collected from FPNG, sickleweed had higher germination in bare soil taken from a patch of sickleweed than in vegetated, unclipped western wheatgrass soil (at P,:S0.05 level). Plot biomass data revealed that in dense sickleweed stands (\u3e40 stems/m2), sickleweed (unclipped plots) reduced the biomass of all vegetation when compared to control (no sickleweed) plots (at P_::s0.05 level). Total biomass harvested from plots with sickleweed clipped at soil surface for one year was not significantly different (at P_::s0.05 level) than total biomass harvested from unclipped and control plots. Native grass biomass was significantly reduced (at P_::s0.05 level) by the presence of sickleweed in both treatment plots when compared to control plots. Biomass of introduced grasses and forbs was not significantly affected by treatments. To determine sickleweed root generative capacity, root segments, 4 cm in length, were cut from the proximal, middle, and distal portions of green house grown sickleweed taproots and buried under 5 cm of FPNG soil in a SDSU greenhouse. After 2 months shoot generation was high (68-82%) in all regions with no significant difference in response by portion of root (P=0.383), which suggests that sickleweed is capable of surviving taproot excision and generating new shoots from small portions of taproot. During the course of this experiment new shoot production from lateral roots was observed in greenhouse grown plants, a phenomenon not previously detected in the field. Lateral spread via rootstocks in a field setting was confirmed when sickleweed shoots began emerging in the second growing season up to 1 m away from potted sickleweed plants transplanted from FPNG into a local garden. The results of this study indicate that sickleweed at FPNG is a perennial plant with high germination capabilities, reproducing and spreading by sprouting from rootstocks, and negatively impacts the production of other vegetation, especially native grasses
Investigation of the Photochemistry and Photophysics of Para-substituted Tertiary Thiocinnamamides
No full textWe report the synthesis and photochemical investigation of a new series of compounds, the tertiary, p-substituted thiocinnamamides. The synthesis centers on a one-pot conversion of the corresponding cinnamamide to the thiocinnamamide via Lawesson’s reagent. Results of semi-empirical calculations predict a frontier orbital structure for the thiocinnamamides that is similar to the analogous cinnamamides. One important difference is the inclusion of the sulfur non-bonding orbital as the highest occupied orbital of the thiocinnamamides. The oxygen non-bonded orbital of the cinnamamides is considerably lower in energy, and does not contribute significantly to the frontier orbital structure. The absorption and emission spectra were measured and are described. The quantum yields for E-Z photoisomerization at various wavelengths were measured and the quantum yields were not found to vary with wavelength. The photostationary states were measured and found to depend on the absorbance of the E and Z isomers at the irradiation wavelength as was expected. Analysis of photoproducts and triplet quenching studies suggest the importance of a triplet state in the photoreactivity of the tertiary thiocinnamamides
