Abstract The passive accumulation of silicon (Si) generally depends on the regulation plant transpiration rates. It is challenging to comprehend how plants use Si adapt shaded habitats where they have low Therefore, we hypothesized that partly due physiological demand rather than being entirely dependent regulation. To test this hypothesis, concentrations and total minerals at various positions foliage branches within crowns Juniperus chinensis L. trees were examined determine whether branch had a allocation resist shade. in consistently higher areas sunny same crown, regardless position crown or foliar age. However, displayed more available light, which linked orientation. Additionally, weak dependence light. These results suggested Si, an energy-saving element supplements cell walls, could also supplement carbon-based components photosynthetic organs balance energy limitations habitats. Thus, high foliage, not branches, was explained by make up for decreased supply caused

Growing crops on marginal lands is a promising solution to alleviate the increasing pressure agricultural land in Europe. Such will however be at same time exposed increased drought and pathogen prevalence, already challenging soil conditions. Some sustainable practices, such as Silicon (Si) foliar fertilization, have been proposed these two stress factors, but not tested under controlled, future climate We hypothesized that Si fertilization would beneficial for climate, cascading effects ecosystem processes, many of them are directly dependent plant health. this hypothesis by exposing spring barley growing macrocosms (three with, three without treatment) 2070 projections an ecotron facility. Using high-capacity monitoring ecotron, we estimated C, water, N budgets every macrocosm. Additionally, measured crop yield, biomass each organ, characterized bacterial communities using metabarcoding. Despite being water conditions, plants did produce more with whatever organ considered. Evapotranspiration (ET) was unaffected, well quality communities. However, 10-day period following applications, significant increase C sequestration, when conditions where significantly drier, while ET remained same. interpreted results less effect treatment than expected compared literature, which could explained high CO

ROOT SYSTEM ARCHITECTURE AND STEM TRAITS OF BREAD WHEAT SEEDLINGS UNDER CONTRASTING WATER REGIMES

The Journal of Animal and Plant Sciences, Journal Year: 2023, Volume and Issue: 34(2), P. 454 - 464

Published: March 24, 2023

Differential response of bread wheat seedlings to contrasting water regimes can be used determine traits related drought tolerance. The F1 offspring from eight crosses and 11 selected parental genotypes were simultaneously grown in hydroponic cultivation-polyethylene glycol (PEG) induced stress vs. control conditions. Criteria for selection maternal paternal desirable terms increased tolerance drought: longer stem length, primary root, large number seminal roots, root dry mass mass, beginning branching at the greatest possible distance angle roots. measured on 14 day old seedlings: length (PRL), first branch (DFBR), roots (NSR), total (TSRL), (ASR), (SL), (RDM), (SDM), ratio (RDM/SDM). Drought led a decrease mean values all by 11% average, except RDM/SDM which was increased. most sensitive trait DFBR (25% reduction), causing systems shallower depth. In conditions stress, strongest statistically significant correlation found among RDM (r = 0.794), SL ASR 0.708), TSRL 0.673). index had positive with SDM, PRL, TSRL, SL, susceptibility NSR. highest heterosis value observed PRL (24.6%) (15.6%) under stress. different directions average DFBR, RDM, indicating differential account when planning breeding Selected as criteria favorable combinations incorporated into pre-breeding schemes, directly or indirectly, aiming achieve Keywords: wheat; stress; heterosis; hydroponics; system architecture.
