“…However, according to Chemikosova et al, [196] it is possible that a change in the ramifications of this pectin makes changes in the interactions between the microfibrils through the matrix impacting the mechanical properties of the fibres. In another paper, Belyak et al [199] conclude from their tests that drought has consequences for fibre yield while a surplus of water does not compromise fibre performance after harvest, as long as there is no lodging.…”

For the past 15 years, there has been tremendous and ever-increasing industrial and academic interest and technological material development concerning plant fibre reinforced composites.Plant fibres can be sourced from a multitude of natural agro-sources, with the preferred choice as a composite reinforcement material often being driven by abundance, geographical location, and historical use. While from a product designer's or engineer's point of view, all plant cell walls are 'similar', there is indeed substantial diversity in plant fibre cell walls. Indeed, a growing body of research demonstrates how cell wall mechanical behaviour is strongly linked to its *Manuscript structure, biochemical composition and the plant growing conditions. At the same time, significant progress has been realised on the knowledge of plant fibre cell wall reinforcement mechanisms in biocomposites. Here, we provide a holistic overview of the main types of plant cell walls used as reinforcements for polymer composites. By synthesising a large body of bibliographic data, we present and discuss the useful diversity in cell walls, illustrated by original schematics for clear comparison. The link between their structures and main properties, in constant link with potential associated composite, is specifically discussed. Then, the different fibre extraction and cultivation modes are discussed and compared, especially through an environmental assessment. We also show how a scientist's point of view on cell wall structure and associated experimental approach and use of characterisation techniques lead to distinct results; following a critical review, we make recommendations on appropriate characterisation techniques for a specific fibre. A final discussion concludes this work by highlighting the pertinent parameters that accurately define a composite reinforcement cell wall. The review will serve as a useful handbook reference for researchers in the field of bio-based materials, and will provide important insights to designers and engineers for appropriate selection of plant fibre cell walls for specific composite applications.

“…We found that fibre content and available yield were higher for the later seeding dates (Tables 2 and 3) resulting in a 170 kg ha (1 , or 53%, increase in fibre yield. This differs from work in Russia (Belyak et al 2007), and points out the challenges of making broad conclusions due to high variation in weather conditions between years. Total stem number and stem diameter were not significantly affected when seeding was delayed from early to late May.…”

“…In this case, temperature and possibly day length may have played an important role in plant growth and seed yield because water is not the limiting factor (Irvine, unpublished data). The impact of seeding date on fibre content and yield has not been documented in Western Canada, but in Russia there is evidence that early seeding increases seed and fibre yields (Belyak et al 2007).…”

. 2010. Impact of production practices on fiber yield of oilseed flax under Canadian prairie conditions. Can. J. Plant Sci. 90: 61Á70. Flax (Linum usitatissimum L.) cultivars commonly grown in western Canada have been developed primarily for seed production. These cultivars tend to be shorter, have lower fibre content, and have lower above-ground biomass than cultivars developed specifically for fibre production. Linseed production is the dominant flax product in western Canada and fibre is a co-product of oilseed production. The objectives of these studies were to evaluate the effects of northern European fibre flax production practices under western Canadian soil and climatic conditions. A number of cultivars in narrow band and solid-seeded planting geometries to determine if they had similar responses. When flax was planted at recommended seeding rates for linseed production, seed and fibre yields were not affected by planting geometry. Increasing the seeding rate from 40 to 120 kg ha Á1 did not affect seed yield regardless of location or seeding date. Even though fibre content was not affected by seeding rate, higher seeding rates increased stem numbers, decreased stem size, reduced the variability in stem size and increased fibre yield. Delaying planting until the end of May increased fibre yields by an average of 35% with no corresponding decrease in seed yield. Since the relative seed and fibre yield responses of a wide range of cultivars were similar with solid seed and narrow band planting geometries, plant breeders can effectively select for higher fibre producing lines using narrow band seed openers using row spacings up to 30 cm apart.Key words: Linseed, row spacing, seeding rate, cultivar, fibre, fibre Irvine, R.

Incidence des pratiques culturales sur le rendement en fibres du lin dans les Prairies canadiennes. Can. J. Plant Sci. 90: 61Á70. Les varie´te´s du lin (Linum usitatissimum L.) couramment cultive´es dans l'ouest du Canada ont essentiellement e´te´de´veloppe´es pour la production de graines. Ces cultivars sont plus trapus et moins fibreux, et ont une plus faible biomasse ae´rienne que les cultivars cre´e´s pour la production de fibres. Les graines demeurent le principal produit tire´du lin dans l'Ouest canadien, les fibres constituant un sous-produit de l'extraction de l'huile. L'e´tude devait pre´ciser l'incidence des pratiques du nord de l'Europe servant a`produire de la fibre de lin en sol canadien, dans les conditions climatiques propres a`l'Ouest du pays. Plusieurs varie´te´s ont e´te´seme´es en bandes e´troites et en culture dense pour ve´rifier comment elles re´agiraient. Quand on se`me le lin aux densite´s recommande´es pour la production grainie`re, la ge´ome´trie de la plantation n'a aucune incidence sur le rendement en graines ou en fibres. Augmenter la densite´de semis de 40 a`120 kg par hectare ne modifie pas le rendement grainier, peu importe l'emplace...
