“…However, the lowest density was not compensated by these primary branches in terms of total dry matter accumulation. Below a minimum stand density of 400 seeds m –2 , compensation by means of apical and basal branches was considered ineffective to reach the equilibrium level of production (Diepenbrock and Porksen 1993). Leitch and Sahi (1999) found a significant linear relationship between number of shoots produced and available space per plant (y=0.05(±0.012)x+1.01; P<0.05).…”

Field experiments were conducted at the Marfa Mawr field station of the University of Wales, Aberystwyth, over 2 years to study the effects of seeding density and row spacing on dry matter accumulation in linseed (Linum usitatissimum L.). Dry matter accumulation increased progressively in all the densities and row spacings with the age of the plants during both the years. However, during 1993 a reduction in dry matter was observed between 106 days after sowing (DAS) and maturity (138 DAS), but this did not happen during 1994. This reduction was considered to be the effect of lodging of the crop and leaf senescence. The lodging took place due to heavy showers of rain and high winds near maturity, and plants were not able to support the weight of capsules. The greater amount of total dry matter accumulated during 1993 compared to 1994 was related to climatic conditions (moist and relatively cool in 1993) on one hand and the total length of the crop life cycle on the other. A total of 391 mm of rain was received during the crop life cycle during 1993 while 229 mm of rain was recorded during 1994. A difference of 2 °C in mean temperature between 1993 and 1994 was also recorded.

“…Similarly, in northern environment, a lower plant density for Buenos Aires, due to the low cold resistance of this variety, was observed in the 1 st year in comparison with the following season, accompanied by a higher number of capsules per square meter and, consequently, by a higher seed yield, compared to 2013-2014. Previous reports (Diepenbrock and Porksen, 1993) have demonstrated as, below a minimum stand density of 400 seeds m -2 , compensation by means of apical and basal branches was considered ineffective to reach the equilibrium level of production. In addition, our results were in agreement with previous reports (Rashid et al, 1998;Lafond, 2001;Lafond et al, 2008), confirming that the three major yield components in linseed are number of capsule per unit area, number of seeds per capsule and seed weight.…”

Agronomical evaluation and chemical characterization of Linum usitatissimum L. as oilseed crop for bio-based products in two environments of Central and Northern Italy

In the recent years, new perspectives for linseed (Linum usitatissimum L.) are open as renewable raw material for bio-based products (Bb), due to its oil composition, and the interesting amounts of coproducts (lignocellulosic biomass). Therefore, the possibility to introduce linseed crop in two environments of central and northern Italy, traditionally devoted to cereal cultivation, has been evaluated. Twoyears field trials were carried out in the coastal plain of Pisa (Tuscany region) and in the Po valley (Bologna, Emilia Romagna region), comparing two linseed varieties (Sideral and Buenos Aires). Agronomical evaluation (yield and yield components), seed and oil characterization (oil, protein content, and fatty acid composition), together with carbon (C) and nitrogen (N) content of the residual lignocellulosic biomass were investigated. The two varieties, grown as autumn crop, showed a different percentage of plant survival at the end of winter, with Sideral most resistant to cold. The achieved results showed significant influence of cultivar, location and growing season on yield and yield components, as well as on chemical biomass composition. In particular, Sideral appeared to be the most suitable variety for tested environments, since higher seed yield (3.05 t ha -1 as mean value over years and locations) and above-ground biomass (6.98 t ha -1 as mean value over years and locations) were recorded in comparison with those detected for Buenos Aires (1.93 and 4.48 t ha -1 of seed production and lignocellulosic biomass, respectively). Interestingly, in the northern area, during the 1 st year, Buenos Aires was the most productive, despite its low plant survival at the end of winter, which determined a strong reduction in plant density and size. In such conditions, the plants produced a larger number of capsules and, consequently, high seed yield (3.18 t ha -1 ). Relevant differences were also observed between the two years, due to the variability of climatic characteristics (temperature levels, and moisture regimes). All these findings confirmed as, in linseed, yield and yield components are quantitatively inherited and influenced by both genotype and environment (location and climate). Varietal and environmental effects were also recorded for oil content and yield, and, generally, good oil percentages, for both genotypes, were found (ranging from 44 to 49% on dry matter basis). Oil from the two varieties was characterized by a stable proportion of polyunsaturated fatty acids with a high content of alpha-linolenic acid (more than 57%), that makes this oil suitable to be used in paints, resins, varnishes, linoleum, polymers and oleochemicals. Finally, our results pointed out as above-and below-ground biomasses, were different in terms of quantity, and chemical characteristics (N, C and C/N ratio). Interesting amounts of N and C could return into the soil by crop residues (stem portions and roots), thus underling the possibility to maintain and/or increase the soil organic matter pool.

“…On the other hand, since the aim is not seed yield, starting branching from above is a desirable feature in terms of increasing the technical stem length (Yıldırım and Arslan, 2013;Kara, 2014). Studies on oil flax show that the height of the first branch is between 12-45 cm (Gubbels, 1978;Diepenbrock and Iwerson, 1989;Endes, 2010;Kara, 2014;Örs and Öztürk, 2018;Aydın, 2020). Although there was no statistical difference between the varieties, the highest number of branches was obtained in the Newtürk variety with 5.1 while the lowest number of branches was obtained in the Sarı 85 variety with 3.8.…”

This study was carried out to determine the effects of some flax varieties on yield and yield components in Ankara ecological conditions in 2021. The study was established with 10 flax varieties 3 replications according to the Randomized Complete Block Design. In the study, plant height (cm), first branch height (cm), number of branches per plant (pieces), number of seeds in the capsule (seed capsule-1), 1000 seed weight (g), number of encapsulated branches per plant (pieces), oil yield (kg ha-1), protein ratio (kg ha-1) and seed yield (kg ha-1) traits were examined. As a result of the research; There were statistically significant differences at the level of 1% between varieties in terms of yield and yield components. In the study, the highest seed yield, oil yield and protein yield (1806 – 599.7 – 428.5 kg ha-1) were obtained from Clli-1412 variety.
