Simultaneous Inhibition

BASF 13-338, a derivative of pyridazinone, inhibits photosynthesis without affecting. respiration in winter wheat (Triticum aestivum L.) at low temperature. This inhibition could account for the previously reported inhibition of frost hardening. Therefore, simultaneous inhibition of linolenic acid accumulation and of frost hardening are probably not causally related.

The correlation between accumulation of linolenic acid in the crowns and roots of winter wheat and its frost hardening at low temperature is indirect. It results from their common requirement for light and low temperature. Light mainly produces energy and carbon reserves. The partial hardening obtained in darkness could be eliminated by preetiolation. The high levels of linolenic acid and frost resistance reached after hardening were maintained for a long time in darkness. The levels of linolenic acid and frost hardiness decreased faster at low temperature in hardened plants after treatment with BASF 13-338, a substituted pyridazinone, than in plants deprived of light. The mode of action of BASF 13-338 is apparently not limited to the inhibition of photosynthesis.

AbstractWe conducted a field study at the Rodale Institute Experimental Farm, Kutztown, Pennsylvania, in a high-P soil to examine the interaction of farming system and tillage on the potential functioning of arbuscular mycorrhizal (AM) fungi. Plots under conventional and low-input systems were either chisel-disked or no-tilled. Winter wheat was planted following the harvest of soybean, and shoots and roots were collected at tillering, jointing, heading, and ripening. Spores of AM fungi were isolated from soil collected at the beginning and end of the growing season. Spore populations and colonization of winter wheat roots by AM fungi were higher under low-input than conventional agriculture. Mycorrhizal fungus colonization occurred at low levels in the tillering stage and increased with plant development. Colonization during the jointing stage was higher in the low-input, no-tilled than in low-input, chisel-disked plots. Spore populations of theGlomus occultum-type group were more numerous in no-tilled than in tilled soil. The nutrient-use efficiency (g of plant biomass per g of plant N or P) of winter wheat depended on plant developmental stage, with a tendency for higher efficiency of the low-input plants at early growth stages, and of conventionally managed plants at more mature stages. Overall, plants grown in chisel-disked plots had higher N and P utilization efficiencies than plants grown in no-tilled plots. Final yield of grain was significantly greater in conventional than low-input plots, especially for no-till, despite the larger population of AM fungi.
