Evaluation of the effect of pre-sowing electron irradiation of barley seeds on plant development and disease incidence

Abstract The effect of electron irradiation of barley seeds of the Vladimir variety on the development of plants, disease incidence and productivity in controlled greenhouse conditions has been studied. It was found that the effectiveness of the effect of seed treatment with low-energy electronic radiation in the dose range of 30–150 kGy on the morphometric parameters of barley largely depends on the accelerating voltage – 130 kV (mode 1) and 160 kV (mode 2). It was noted that irradiation suppressed the formation of chlorophyll a and b and carotenoids in barley leaves at all doses and irradiation regimes and, at the tendency level, reduced the infestation of Bipolaris sorokiniana plants in the tillering and heading phases. It was shown that irradiation of seeds caused an increase in the total tillering of plants (mode 2), but at the same time reduced the productive tillering. Electron irradiation caused an increase in the mass of 1000 grains and did not affect the yield of grain and straw.

The Stability

AbstractThe stability of the molecular self-assembled monolayers (SAMs) is of vital importance to the performance of the molecular electronics and their integration to the future electronics devices. Here we study the effect of electron irradiation-induced cross-linking on the stability of self-assembled monolayer of aromatic 5,5′-bis(mercaptomethyl)-2,2′-bipyridine [BPD; HS-CH2-(C5H3N)2-CH2-SH] on Au (111) single crystal surface. As a refence, we also study the properties of SAMs of electron saturated 1-dodecanethiol [C12; CH3-(CH2)11-SH] molecules. The stability of the considered SAMs before and after electron-irradiation is studied using low energy Ar+ cluster depth profiling monitored by recording the X-ray photoelectron spectroscopy (XPS) core level spectra and the UV-photoelectron spectroscopy (UPS) in the valance band range. The results indicate a stronger mechanical stability of BPD SAMs than the C12 SAMs. The stability of BPD SAMs enhances further after electron irradiation due to intermolecular cross-linking, whereas the electron irradiation results in deterioration of C12 molecules due to the saturated nature of the molecules. The depth profiling time of the cross-linked BPD SAM is more than 4 and 8 times longer than the profiling time obtained for pristine and BPD and C12 SAMs, respectively. The UPS results are supported by density functional theory calculations, which show qualitative agreement with the experiment and enable us to interpret the features in the XPS spectra during the etching process for structural characterization. The obtained results offer helpful options to estimate the structural stability of SAMs which is a key factor for the fabrication of molecular devices.
