“…In species producing two or more seed types, there is a tendency for seed functions to diverge, each type being adapted to an aspect of the environment to which it is predisposed, whilst being buffered by the other seed type (Mandak, 1997). Moreover, it has been proven that seeds which vary in appearance also vary in chemical composition (Aniszewski et al 2001). This suggests that if we are to manipulate the chemical constituents of seeds in general, it is very important to classify seeds according to types and physical properties.…”

Isozyme patterns for aspartate amino transferase, alcohol dehydrogenase and superoxide dismutase were evaluated in 60 accessions of eleven Vicia taxa occurring in Algeria. The three enzymatic systems revealed 25 morphs of different frequency encoded by 7 loci. Similarity between species and accessions was estimated by Euclidean distances based on presence or absence of bands. The UPGMA method was utilized for the groupings and dendrogram construction. The dendrogram presented 2 major groups, each one corresponding to a taxonomic level where accessions of the same species grouped together. Taxa-specific bands were identified. In parallel, 12 physical seed properties namely: length, width, thickness, arithmetic diameter, geometric diameter, sphericity, surface area, volume, square mean diameter, equivalent diameter, seed aspect ratio and 1000 seed weight were calculated. By cluster analyses based upon them, the material has been classified into 2 major groups with no correspondence with the current taxonomy. A Principal Component Analysis was undertaken to distinguish physical properties which contribute the most to accessions distinction. Mantel test was used to assess correlation between the three enzymatic systems studied one side and between enzymes polymorphism and physical seed properties another side.

The aim of this study was to examine the relationship between oil content and seed size in 32 castor accessions. The oil content and fatty acid composition were determined using the Soxhlet extraction method and capillary gas chromatography. The results indicated that the values of seed characteristics were very variable. The crude fat percentage among the accessions ranged from 36.62% to 49.19%. The content of ricinoleic acid was highest in all fatty acid compositions, from 82.3% to 88.6%. The other fatty acids appeared at a low content (less than 1%). Correlation analysis revealed that seed size was significantly positively correlated with 100-seed weight, the crude fat content and the ricinoleic acid content but showed negative correlation with the content of palmitic and arachidic acids. Hierarchical clustering of castor cultivars separated the 32 accessions into four independent clusters. The obtained results provide useful information for further research in breeding and utilization of castor oil.

“…In Finland, Washington lupin (L. polyphyllus Lindl.) is a garden escapee, which flourishes by the roadsides and indicates the general potential of lupins to adapt successfully to northern conditions (Aniszewski et al 2001). Lupins are also likely to benefit from climate induced changes in Finnish conditions and could represent a valuable addition to the group of nitrogen fixing protein crops in the future.…”

Climate change offers new opportunities for Finnish field crop production, which is currently limited by the short growing season. A warmer climate will extend the thermal growing season and the physiologically effective part of it. Winters will also become milder, enabling introduction of winter-sown crops to a greater extent than is possible today. With this study we aim to characterise the likely regional differences in capacity to grow different seed producing crops. Prolongation of the Finnish growing season was estimated using a 0.5º latitude × 0.5º longitude gridded dataset from the Finnish Meteorological Institute. The dataset comprised an average estimate from 19 global climate models of the response of Finnish climate to low (B1) and high (A2) scenarios of greenhouse gas and aerosol emissions for 30-year periods centred on 2025, 2055 and 2085 (Intergovernmental Panel on Climate Change). Growing season temperature sums that suit crop growth and are agronomically feasible in Finland are anticipated to increase by some 140 °Cd by 2025, 300 °Cd by 2055 and 470 °Cd by 2085 in scenario A2, when averaged over regions, and earlier sowing is expected to take place, but not later harvests. Accordingly, the extent of cultivable areas for the commonly grown major and minor crops will increase considerably. Due to the higher base temperature requirement for maize (Zea mays L.) growth than for temperate crops, we estimate that silage maize could become a Finnish field crop for the most favourable growing regions only at the end of this century. Winters are getting milder, but it will take almost the whole century until winters such as those that are typical for southern Sweden and Denmark are experienced on a wide scale in Finland. It is possible that introduction of winter-sown crops (cereals and rapeseed) will represent major risks due to fluctuating winter conditions, and this could delay their adaptation for many decades. Such risks need to be studied in more detail to estimate timing of introduction. Prolonged physiologically effective growing seasons would increase yielding capacities of major field crops. Of the current minor crops, oilseed rape (Brassica napus L.), winter wheat (Triticum aestivum L.), triticale (X Triticosecale Wittmack), pea (Pisum sativum L.) and faba bean (Vicia faba L.) are particularly strong candidates to become major crops. Moreover, they have good potential for industrial processing and are currently being bred. Realisation of increased yield potential requires adaptation to 1) elevated daily mean temperatures that interfere with development rate of seed crops under long days, 2) relative reductions in water availability at critical phases of yield determination, 3) greater pest and disease pressure, 4) other uncertainties caused by weather extremes and 5) generally greater need for inputs such as nitrogen fertilisers for non-nitrogen fixing crops.
