In this study, novel rod-like and block-like CaO crystals were prepared after calcinating three types of CaCO3 precursors containing dumbbell-like, wheat spike-like and microsphere-like morphologies at 1000 °C for 3 h.

The paper presents data on the evaluation of the effect of ten preparations based on humic substances and silver (FlorhGumat, FloraS, Edagum, Fitop Flora-S, Zerebra agro, BatyrMax, Batyr 40N, Batyr 40N + MAX, Azofoska) on the productivity of spring soft wheat. The productivity of wheat was studied in indicators of: the phase of the plant (according to the scale of Eucarpia) the number of germinal, coleoptile roots, the length of the germinal, coleoptile roots, the number of nodal roots, the length of nodal roots, the summary mass of the roots, the mass of the vegetative part of the plants, the length of the wheat spike, the number of spikelets in the wheat spike, the number of grains in the wheat spike, the mass of the spike, the height of the plants, the area of the flag leaf, the area of the pre-flags leaf, productive tilling capacity, general tilling capacity. Out-root treatment of plants with preparations in appropriate concentrations was carried out in the evening hours during the phases of wheat tillering and the formation of a flags leaf. The greatest influence on the productivity of wheat was provided by the preparation BatyrMax. The preparation Edagum showed maximum effectiveness in the number of reliable positive changes in the productivity of wheat compared to the control (untreated plants) and background (the plants were treated with the preparation Azofoska). Similarities in the action of Edagum, Phytop Flora-S and Zerebra Agro, Batyr 40N + Max on the changes in the most of the wheat productivity indicators were revealed. There was no statistically significant effect on the yield of Flora-S, FlorHumat, Azofoska.

Wheat is the main food crop today world-wide. In order to improve its yields, researchers are committed to understand the relationships between wheat genotypes and phenotypes. Compared to progressive technology of wheat gene section identification, wheat trait measurement is mostly done manually in a destructive, labor-intensive and time-consuming way. Therefore, this study will be greatly accelerated and promoted if we can automatically discover wheat phenotype in a nondestructive and fast manner. In this paper, we propose a novel pipeline based on 3D morphological processing to detect wheat spike grains and stem nodes from 3D X-ray micro computed tomography (CT) images. We also introduce a set of newly defined 3D phenotypes, including grain aspect ratio, porosity, Grain-to-Grain distance, and grain angle, which are very difficult to be manually measured. The analysis of the associations among these traits would be very helpful for wheat breeding. Experimental results show that our method is able to count grains more accurately than normal human performance. By analyzing the relationships between traits and environment conditions, we find that the Grain-to-Grain distance, aspect ratio and porosity are more likely affected by the genome than environment (only tested temperature and water conditions). We also find that close grains will inhibit grain volume growth and that the aspect ratio 3.5 may be the best for higher yield in wheat breeding.

Varieties of common wheat (Triticum aestivum L. em. Thell.) of low wheat–rye crossability showed increased seed set if pollinated with cultivated rye (Secale cereale L.) before the wheat spike attained maximum receptivity to wheat pollen (before the stage of first anthesis). After first anthesis the development of hybrid seed progressively deteriorated with increasing lateness of pollination. Premature or 'bud' pollination may be a useful approach for overcoming intergeneric cross-incompatibility barriers in the Triticineae.

Estimates of the base temperature for grain filling duration of wheat (Triticum aestivum L.) differ between outdoor and indoor studies. This study was set up to determine whether this difference could be attributed to variation in spike-air temperature differentials. Spike and/or spikelet temperatures were determined in wheat grown outdoors as well as indoors. Spike temperature, measured with an infrared thermometer, of wheat grown outdoors with adequate water supply was 1.5 °C greater than air temperature while spikelet temperature measured with a thermocouple closely approximated air temperature. In indoor grown wheat, on the other hand, regardless of the magnitude of air temperature, spikelet temperature was found to be 3–4 °C above that of air when lights were on. Estimating the base temperature for grain filling duration with data from a previous indoor study, with compensation for the 3–4 °C increase in spikelet temperature, resulted in 8.8 °C base temperature for grain filling duration, comparable to that obtained in outdoor studies. Differences between outdoor and indoor studies may thus reflect spike-air temperature differentials. Estimation of the base temperature for grain filling with air temperature appears appropriate for outdoor studies. Key words: Triticum aestivum (L.), base temperature, grain filling duration, wheat
