Sowing Dates

In order to elucidate the effect of sowing date on the yield and yield components of oilseed rape (Brassica napus L.), three varieties - Tower, Rafal and Global - were sown from 7 November to 22 December 2000-01 on four dates at an interval of 15 days in the Dezful region of Iran. A split-plot design based on randomized complete blocks with four replications was used in the experiment, where the sowing dates and cultivars formed the main and subplots, respectively. Variables including plant height, axillary branches/plant, pods/plant, seeds/pod, single seed weight, biomass, seed oil content and seed yield were measured. The soil of the experimental site had a loamy clay texture. The site had 250 mm annual precipitation and was located in the semi-arid zone. The results showed that the sowing date had a highly significant effect on morphological characteristics, yield components, oilseed rape yield and seed oil content. A delay in the sowing date caused a reduction in all the yield components especially in pods/plant, and in oilseed yield, which dropped from 285 g m-2 when sown on 7 November to 135 g m-2 when sowing was delayed to 22 December. Variations in sowing dates had different effects on the individual yield components, with pods/plant, seeds/pod and single seed weight decreasing to the greatest extent. The significant effect of variety on all characters with the exception of single seed weight indicated that there were genetic differences between the studied cultivars. Oilseed yield showed significantly positive correlations with pods/plant (r=0.93), single seed weight (r=0.83) and seeds/pod (r=0.66). The results of path analysis showed that pods/plant and seeds/pod had the highest positive and negative effects on oilseed yield, respectively. Finally, considering the susceptibility of pods/plant to variations in sowing date and the importance of this character in the size of the oilseed yield, a delay in the planting date in the Dezful region was found to reduce the oilseed yield through a reduction in pods/plant.

Eryiğit, T., Akiş, R. and Kaya, A. R. 2015. Screening of different nitrogen rates and intra-row spacing effects on yield and yield components of safflower (Carthamus tinctorius L.) under microclimate conditions, Iğdır Plain, Turkey. Can. J. Plant Sci. 95: 141–147. The yield of safflower (Carthamus tinctorius L.) is affected by many factors, among which nitrogen fertilization and plant density are significant. This study was conducted as a split plot in a randomized complete block design arrangement with four replications, during the successive seasons 2011 and 2012, to determine the effects of nitrogen application rate and intra-row spacing on the growth, yield and yield components of safflower under the ecological conditions of the Iğdır Plain, Turkey. The main plots were three intra-row spacing (IRS1, IRS2 and IRS3) and subplots were four nitrogen rates (N1, N2, N3 and N4). Intra-row spacing had significant effects on all parameters except plant height and seed oil content. There were significant effects of fertilizer rate on all parameters except seed oil content. The interaction of nitrogen rate and years had significant effects on seed yield. Correlations showed significant negative results between 1000-seed weight and seed oil content (−0.217). However, there was a high seed yield in 2011 compared with 2012. Among intra-rows, IRS2 and IRS3 gave greater yield compared with IRS1, while N3 gave a higher yield than other N rates (0, 100, 150, 200 kg ha−1) in both years of the study, especially 2011.

Developmental Switches

Transcription factors (TFs) and their complex interplay are essential for directing specific genetic programs, such as responses to environmental stresses, tissue development, or cell differentiation by regulating gene expression. Knowledge regarding TF–TF cooperations could be promising in gaining insight into the developmental switches between the cultivars of Brassica napus L., namely Zhongshuang11 (ZS11), a double-low accession with high-oil- content, and Zhongyou821 (ZY821), a double-high accession with low-oil-content. In this regard, we analysed a time series RNA-seq data set of seed tissue from both of the cultivars by mainly focusing on the monotonically expressed genes (MEGs). The consideration of the MEGs enables the capturing of multi-stage progression processes that are orchestrated by the cooperative TFs and, thus, facilitates the understanding of the molecular mechanisms determining seed oil content. Our findings show that TF families, such as NAC, MYB, DOF, GATA, and HD-ZIP are highly involved in the seed developmental process. Particularly, their preferential partner choices as well as changes in their gene expression profiles seem to be strongly associated with the differentiation of the oil content between the two cultivars. These findings are essential in enhancing our understanding of the genetic programs in both cultivars and developing novel hypotheses for further experimental studies.

Abstract: The objective of this work was to evaluate the oil content and characters related to fiber quality and yield in cotton lines (Gossypium hirsutum), in order to select genotypes with high oil content and acceptable levels of the other characters. Twenty-two F6 lines and three checks were cultivated in three field trials - two in the municipality of Apodi, in the state of Rio Grande do Norte, and one in the municipality of Barbalha, in the state of Ceará, both in Brazil. The genetic parameters and the genetic gain from selecting 20% of the lines were estimated according to their means in each environment and in the group of environments. Regarding oil content, there is genetic variability, and the selection based on the overall mean is indicated, since this character showed high heritability, with 4.58% expected gain. The lines selected with this criterion have oil contents between 23.52 and 24.51%, which are higher than those of the Brazilian cultivar BRS Aroeira with the highest grain oil content (22.04%).
