The field sites were selected to cover a wide range of climatic conditions in Norway. Five weekly yield samplings during the regrowth periods were fitted to an expolinear growth equation to determine initial maximum relative regrowth rates (R m) and maximum regrowth rates (C m). The step from actual to potential rates was accomplished by weighting the obtained rates with a weather index. For both species R m was highest after an initial cut at the early vegetative stage. It was reduced by 50% at jointing, after which there was no change with later cuts. For both species the C m declined sharply with cutting time through the early stages of phenological development, whereas from early heading to anthesis there was no significant change. Compared with timothy, the C m va...","PeriodicalId":40817,"journal":{"name":"Acta Agriculturae Scandinavica Section B-Soil and Plant Science","volume":"20 1","pages":"209-215"},"PeriodicalIF":1.6,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72970942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considerable variation in the effect of collection time was obtained between years. The highest rooting percentage (90%), including all environments determined after 30 days, occurred in 1993 on plant material collected early in the season. In 1994 material collected later rooted better. Overall rooting percentage was higher in the outdoor plastic tunnels than in the greenhouse. In tunnels, rooting was improved by bottom heat, which accelerated the rooting process. Softwood cuttings required more time to form roots than did hardwood cuttings.","PeriodicalId":40817,"journal":{"name":"Acta Agriculturae Scandinavica Section B-Soil and Plant Science","volume":"15 1","pages":"242-247"},"PeriodicalIF":1.6,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86416443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Only a few conidia were trapped outside the plot. At one of the locations, no conidia were observed. The highest conidial record, 47 conida per m3 air, was observed inside the carrot plot, during 1 h in September 1985 at one location. Only one or two conida were trapped on most of the other days.

Densities ranged from 20 to 130 plants m−2. Three response variables, number of pods per plant, seed weight per plant and dry matter per plant, were studied using different regression models to examine their relationship with density. Transformations were used to improve the fit of the models. Pods per plant, seed weight and dry matter per plant decreased as plant density increased. Seed weight and dry matter m−2 responded similarly to varying plant density for the two cultivars. For all response variables, the inverse exponential model gave the best fit to the data, indicating the existence of an optimum density, which was about half the official recommended sowing density.","PeriodicalId":40817,"journal":{"name":"Acta Agriculturae Scandinavica Section B-Soil and Plant Science","volume":"35 1","pages":"129-133"},"PeriodicalIF":1.6,"publicationDate":"1999-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73517711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nitrate content in plant stem tissue sap collected at Zadoks growth stages GS 31 and GS 49 of winter wheat in 11 annual field trials in south-east Norway in the years 1993-96 was measured with Merckoquant test strips with a Nitracheck Meter. Relationships between NO3 - concentrations and final yields were good within individual trials, but when the results from all trials were pooled, the NO3 - concentration was a poor predictor of final yields. This study suggests that the critical nitrate values required in plant stem sap for sufficient grain protein content for bread-baking quality are 4000 ppm NO3 - at GS 31 and 2000 ppm at GS 49 in situations with a single N application in the spring.
