“…SY increased by 28.4% in N+ compared to N− plots (4.64 ± 0.39 vs. 3.61 ± 0.51 t ha −1 , respectively) and the NConc increased by 4.7% (3.51 ± 0.06 vs. 3.36 ± 0.11 %) ( Figure 4, Table 2). NConc and OilConc were negatively correlated, confirming previous findings [43,44]. The GLS and TSW were essentially cultivar dependent.…”

In-Field Observation of Root Growth and Nitrogen Uptake Efficiency of Winter Oilseed Rape

et al. 2020

Field trials were conducted with two nitrogen applications (0 or 240 kg N ha−1) and three modern cultivars of winter oilseed rape (Brassica napus L.) previously selected from a root morphology screen at a young developmental stage. The purpose is to examine the relationship between root morphology and Nitrogen Uptake Efficiency (NUpE) and to test the predictiveness of some canopy optical indices for seed quality and yield. A tube-rhizotron system was used to incorporate below-ground root growth information. Practically, clear tubes of one meter in length were installed in soil at an angle of 45°. The root development was followed with a camera at key growth stages in autumn (leaf development) and spring (stem elongation and flowering). Autumn was a critical time window to observe the root development, and exploration in deeper horizons (36–48 cm) was faster without any fertilization treatment. Analysis of the rhizotron images was challenging and it was not possible to clearly discriminate between cultivars. Canopy reflectance and leaf optical indices were measured with proximal sensors. The Normalized Difference Vegetation Index (NDVI) was a positive indicator of biomass and seed yield while the Nitrogen Balance Index (NBI) was a positive indicator of above-ground biomass N concentration at flowering and seed N concentration at harvest.

“…In addition, a strong negative correlation between oil and protein accumulation has been observed in protein-storing seeds like soybean (Chung et al, 2003), as well as in oilstoring seeds like rapeseed (Grami et al, 1977;Jolivet et al, 2013), sunflower (Li et al, 2017) or the model plant Arabidopsis thaliana ( Fig. 4), suggesting that seed filling in these species is highly constrained and that manipulating both components independently may be difficult.…”

Western Europe oleoproteaginous species like rapeseed mainly accumulate oil and protein in their seeds. To become competitive with soybean, seed protein quantity and quality should be improved in rapeseed. The negative correlation existing between seed protein and oil content apparently prevents the possibility to increase protein content without affecting oil content. Exploration of natural and induced genetic variability in the model plant Arabidopsis thaliana allows the identification of several genotypes impaired in this negative correlation. Different genetic approaches have been undertaken in order to isolate genetic factors responsible for the tight control of seed oil and protein homeostasis and this negative correlation. Once isolated in this model plant, such genetic determinants will be identified in important crops such as rapeseed or other oilseed crops in order to manipulate both components independently and thus produce on purposed seeds. In the long term, this research will help breed new varieties that could contribute to reduce Europe’s dependence on US soybean import.

“…Reports on isolating oil bodies can be traced back to at least the 1970s. Oil bodies have been isolated from a range of seeds: soybean [15], sunflower seed [16], almond [17,18], walnut [19] Arabidopsis [20], and maize germ [21]. Characterisation of oil bodies extracted from different seed (rapeseed, sesame, cotton, flax, and maize) and nuts (peanut) has shown that the size of these organelles always falls within a narrow range (0.6-2.0 m) with an isoelectric point from 5.7 to 6.6 [22].…”

Influence of Pecan Nut Pretreatment on the Physical Quality of Oil Bodies

A supply of pure, intact oil bodies is essential for carrying out morphological and biochemical studies of these plant organelles and exploring their application. Preparation requires a carefully controlled breakage of plant cells, followed by separation of the oil bodies from cytoplasm and cell debris. This paper focuses on the recovery and characterisation of oil bodies from pecan nuts where no work has been published to date. The results showed that soaking softens the nut tissue and appears to reduce the damage to oil bodies during grinding and centrifugal force must be carefully selected to minimise oil bodies damage on recovery. A 24 h soaking time coupled with a 5500 RCF recovery force allows for the recovery of intact pecan nut oil bodies.
