The shoot and root growth in terms of root length, shoot length, root and shoot weight was significantly inhibited at 100 μm Cr (VI) with respect to control.
Expression of rolD and ORF13 correlated with reduced aerial plant coverage, shoot weight, shoot: root ratio and increased flower density and flower width relative to plant coverage, thus being considered of particular interest in Mecardonia breeding.
Morpho-physiological parameters for shoot length, root length, seedling height, shoot weight, root weight, fresh biomass, dry biomass and root collar diameter were assessed.
In comparison, the pairs of traits quercetin and shoot weight, and root:shoot ratio and shoot weight showed strong negative associations (directional vectors approaching 180°).
We measured shoot weight, average root diameter, as well as root weight, length, volume, and area.
Between the two strain treatments, half of the measured phenotypes had at least one antagonistic QTL (Naut = leaf number, average fruit weight, shoot weight; Sals = number of fruit, shoot weight; Tables 2 and 3).
Accordingly, shoot weight is highly variable (range 0.024 0.834 g dw shoot-1) and differs significantly between regions (Kruskal-Wallis test, P<<0,001, Figure 5(c)).
When the pathogen was allowed to colonise the soil in section B at the time of sowing or 10 d after sowing it failed to cause significant reduction in root and shoot weights compared to uninfested control pots.
Relative to shoot dry weight, taproot depth decreased with increasing water availability.
An was 17% higher in the second year than that in the first year and the conversion rate of photosynthetic production to shoot dry weight for developed saffron increased by about 47% due to leaf area index increase.
