In freezing period, soil temperature gradients of PM and CK were positive, with temperature becoming sent toward top earth layer, additionally the conduction strength in PM therapy ended up being greater than CK. During the melting duration, soil temperature gradient of PM has also been good, with temperature being sent toward upper earth layer, and that of CK was conversed. Soil liquid in PM treatment transported to upper soil level during freezing-thawing period, but it appeared a “down-up-down” action mode under CK in freezing period, “up-down” in thawing duration. There clearly was definitely correlation between temperature and moisture gradient into the freezing period under both PM and CK treatments, with closer correlation in PM than CK. During melting period, earth temperature and dampness gradient had been positively correlated in PM therapy with earth temperature and dampness moved upward synchronously, while that in CK had been adversely correlated with soil heat and moisture simultaneously relocated to the reduced layer earth. Driven by soil temperature and moisture gradient, earth temperature in 0-10 cm, 10-20 cm and 20-30 cm layers increased by 1.13-1.34 ℃, 0.96-1.24 ℃ and 0.89-1.32 ℃, while normal soil water content increased by 3.4%-5.6%, 1.4%-2.2per cent and 6.7%-7.8%, correspondingly in PM therapy before sowing. Our outcomes indicated that PM could supply water as well as heat security for re-greening of cold weather crop and sowing, introduction and seedling of spring-sown plants in semi-arid areas.Effects of five different nitrogen application rates (i.e., N0, 0 g·kg-1; N1, 0.05 g·kg-1; N2, 0.1 g·kg-1; N3, 0.15 g·kg-1; N4, 0.2 g·kg-1) on the growth of seedlings of eight different quinoa cultivars were investigated in a pot experiment. The results indicated that 1) Across various nitrogen application rates, cultivar GB22 and OY had the best biomass, but cultivar B2 had the lowest value. The best flower size proportion, stem mass ratio, root mass proportion, and leaf mass ratio had been found in cultivar B2, GB22, R1, and W23, respectively. 2) The rate of nitrogen application significantly affected seedling growth. Weighed against the control (N0), the most net photosynthetic price and biomass buildup were substantially greater when you look at the reduced nitrogen applications (for example., N1 and N2 remedies), but had been reduced in the larger nitrogen programs (for example., N3 and N4 treatments). The significant interactions between cultivar and nitrogen application rate on plant biomass suggested that different quinoa cultivars responded differently to nitrogen rate. The maximum nitrogen application price (Nopt) needed for cultivar R1, MY11, GB22 and OY ended up being 0.05 g·kg-1; while that of cultivar GB11, DB, and B2 had been 0.1 g·kg-1; but for cultivar W23, Nopt was significantly less than 0.05 g·kg-1. 3) The communications between cultivar and nitrogen application rate significantly affected biomass allocation. Underneath the highest nitrogen price used (in other words., lower than 0.2 g·kg-1), the flower and leaf biomass allocation increased with the increasing nitrogen prices. 4) Across various cultivars and nitrogen application prices, plant biomass had been definitely correlated to the optimum net photosynthetic rate, plant height, surface diameter, and particular leaf location, respectively. These outcomes supplied important information when it comes to nutrition handling of different quinoa cultivars.To explore the consequences of different intercropping types on development, nutrition consumption, and fruit top-notch oriental melon, we examined plant height, stem diameter, root activity, contents of mineral elements (N, P, K, Ca and Mg), and fruit high quality and yield of oriental melon underneath the oriental melon monoculture (MM), intercropping of fennel/oriental melon (FM), tillered-onion/oriental melon (TM), or wormwood/oriental melon (WM). Results revealed that plant height of intercropping treatments was substantially more than that of the monoculture over time. The stem diameter of the FM and TM treatments ended up being dramatically greater than compared to the MM therapy, while there is no significant difference amongst the WM and MM remedies. In the stretch tendril stage, fruit environment stage, and fruit growing phase, root activity of FM treatment ended up being substantially greater than fgfr signals that of MM and TM treatments. The mine-ral elements articles of oriental melon flowers in three intercropping remedies were higher than that in MM treatment in different levels, with the mine-ral elements items of FM therapy becoming greater than that of TM and WM treatments. The solitary good fresh fruit weights of FM and TM remedies would not vary from the MM treatment. The fruit high quality indices of FM therapy were not lower than MM treatment, while some fresh fruit quality indices (such as the contents of sugar, fructose, and sucrose) of WM and TM remedies had been lower than that under MM therapy. In summary, fennel ended up being a suitable types for intercropping with the oriental melon.To investigate the effects of H2S on mitochondrial functions under low temperature stress, we analyzed the results of 0.05 mmol·L-1 NaHS and 15 μmmol·L-1 HT (hypotaurine and H2S scavenger) on mitochondria anti-oxidant enzyme activities and mitochondrial permeability transition pore, mitochondrial membrane layer fluidity, mitochondrial membrane layer potential, Cyt c/a proportion and H+-ATPase task in sweet cherry stigma and ovary with sweet cherry variety Zaodaguo under -2 ℃ low temperature tension. The outcomes indicated that low-temperature tension enhanced the concentrations of mitochondrial H2O2 and MDA, improved the mitochondrial membrane layer permeability, but decreased the mitochondrial membrane layer fluidity, membrane potential, Cyt c/a and H+-ATPase acti-vity. Application of NaHS at 0.05 mmol·L-1 could effectively lessen the levels of H2O2 and MDA, and hold higher activities of SOD, POD and CAT of mitochondrial for extended time. Moreover, application of 0.05 mmol·L-1 NaHS could reduce mitochondrial membrane permeability while enhance mitochondrial membrane fluidity, membrane potential, Cyt c/a and H+-ATPase activity in stigma and ovary under low-temperature anxiety. The consequences of NaHS were completely offset by HT addition. The outcome proposed that exogenous H2S could alleviate the oxidative damage on stigma and ovary anxiety through decreasing H2O2 accumulation, managing mitochondria antioxidant system, increasing H+-ATPase task, and mitigating mitochondria function under low temperature.
