Abstract:
... Two pot experiments have been conducted to study separately the influence of two factors on applied P utilization by four crops: flax (Linum usitatissimitm, L., cv. ‘Redwood’), wheat (Triticum vulgare L., cv. ‘Manitou’), rape (Brassica napus L., cv. ‘Tanka’), and buckwheat (Fagopyrum esculentum Moench). These crops vary greatly in their ability to utilize P from band or pelletlike phosphate applic ...

Abstract:
... Remote sensing techniques supply useful crop information in large area crop survey programs. In such programs, however, the spectral and spatial resolution, measurement geometry, and environmental correction cap abilities have been limited by the fixed and truly remote nature of the sensor platform. To extend the applications of existing systems, or to use new systems, some workers have started sm ...

Abstract:
... Recessive genetic male-sterility has been widely used to facilitate crossing in recurrent selection programs in autogamous crop species. Dominant genetic male-sterility, on the other hand, has not been widely used. Mass and half-sib family selection schemes have been described for the dominant male-sterile program. Our objective was to describe S₁ family recurrent selection schemes and expected se ...

LEA mRNAs and proteins can be induced to appear at other stages in the plant's life by desiccation stress and/or treatment with the plant hormone abscisic acid (ABA). A role it, protecting plant structures during water loss is likely for these proteins, with ABA func ...

Abstract:
... Several investigators have questioned the use of the ¹⁵N natural-abundance method of estimating N₂ fixation because of variability in soil δ¹⁵N and small differences between the δ¹⁵N of soil N and atmospheric N. Investigations were conducted to compare the ¹⁵N natural-abundance and ¹⁵N-isotope-dilution methods for estimating N₂ fixation of field-grown pea (Pisum sativum L.) and lentil (Lens culina ...

Abstract:
... The importance of the two chiral centers at C-3 and C-7 in the molecular structure of jasmonic acid in plant responses was investigated. We separated methyl jasmonate (MeJA) into (3R)- and (3S)-isomers with a fixed stereochemistry at C-3, but epimerization at C-7 is possible. The four isomers of the nonepimerizable analog 7-methyl MeJA were synthesized. These six esters and their corresponding aci ...

Abstract:
... Enhanced corn (Zea mays L.) yield responses to rotation in notill systems may be due to the types and amounts of surface-placed plant residue. Research in 1989, 1990, and 1995 evaluated no-till corn yield response to various preceding crops and examined whether inrow residue removal affected no-till corn response to rotation crops. The soil was an imperfectly drained loam (medium, mixed, weakly to ...

Abstract:
... Many plants increase in freezing tolerance in response to low, nonfreezing temperatures, a phenomenon known as cold acclimation. Cold acclimation in Arabidopsis involves rapid cold-induced expression of the C-repeat/dehydration-responsive element binding factor (CBF) transcriptional activators followed by expression of CBF-targeted genes that increase freezing tolerance. Here, we present evidence ...

Abstract:
... The critical period of weed control is the portion of the life cycle of a crop during which it must be kept weed-free to prevent yield loss due to weed interference. The advent of herbicide-resistant canola (Brassica napus L.) varieties in western Canada has meant that there are now more options for postemergence weed control in canola, and this has prompted increased interest in identifying the o ...
