In Situ Rainwater Harvesting System Slows Forest Decline through Increasing Soil Water Content, Fine-Root Traits, and Plant Hydraulic Conductivity

Forests, Год журнала: 2024, Номер 15(3), С. 571 - 571

Опубликована: Март 21, 2024

Large-scale vegetation restoration campaigns have been implemented on the Chinese Loess Plateau, which resulted in higher soil moisture deficits this region. This, turn, has hampered healthy growth of planted trees, leading to a decline and, severe cases, mortality trees. Therefore, rational regulation and utilization rainwater, primary water source region, may alleviate drought stress, ensuring sustainability ecosystem. In study, we investigated impact situ rainwater collection infiltration systems (IRCISs) water, fine-root distribution, xylem vascular, hydraulic conductivity characteristics declining Robinia pseudoacacia forests. The results demonstrated that application an IRCIS can effectively increase plant available content (0–5.0 m) particular, treatment significantly increased conduit diameter while substantially reducing percentage loss both roots branches. Furthermore, reduced root biomass distribution depth during wet dry years. This implies IRCISs are beneficial for survival. findings study significant devising strategic methodologies planning management resources.

Increasing soil and water salinity threatens global agriculture, particularly affecting rice. This study investigated the residual effects of microbial biochar nitrogen fertilizer in mitigating salt stress paddy regulating biochemical characteristics rice plants. Two varieties, Shuang Liang You 138 (SLY138), a salt-tolerant, Jing 534 (JLY534), salt-sensitive, were grown under 0.4 ds/m EC (S0) 6.84 (S1) glass house controlled conditions. Three types biochar-rice straw (BC), fungal (BF), bacterial (BB)-were applied alongside two (N) rates (60 kg ha

RNA-seq reveals the gene expression in patterns in Populus × euramericana 'Neva' plantation forests under different precision water and fertilizer-intensive management

Research Square (Research Square), Год журнала: 2024, Номер unknown

Background: Populus spp. is a crucial fast-growing and productive tree species extensively cultivated in the mid-latitude plains of world. However, impact intensive cultivation management on gene expression plantation forestry remains largely unexplored. Results: Precision water fertilizer-intensive substantially increased key enzyme activities nitrogen transport, assimilation, photosynthesis (1.12–2.63 times than CK) Populus × euramericana 'Neva' plantation. Meanwhile, this approach had significant regulatory effect poplar plantations. 1554 differential genes (DEGs)were identified drip irrigation (ND) compared with conventional irrigation. Relative to ND, 2761–4116 DEGs, predominantly up-regulated, were under three fertilization combinations, among which 202 DEGs mainly regulated by fertilization. Moreover, reduced cell wall synthesis-related reduce unnecessary transport. fertilizer promotes synergistic regulation carbon metabolism up-regulates major transport assimilation processes (5 DEGs), (15 plant hormone signal transduction (11 DEGs).

Sex-Related Differences of Ginkgo biloba in Growth Traits and Wood Properties

Forests, Год журнала: 2023, Номер 14(9), С. 1809 - 1809

Опубликована: Сен. 5, 2023

Ginkgo biloba is one of the most widely cultivated dioecious timber trees in China. Understanding sex-related differences and how they affect growth traits wood properties crucial for informed management optimal utilization ginkgoes. In present study, we collected 42 ginkgo samples conducted DNA molecular identification to determine their sex. The result was a 1:1 ratio male female specimens. addition, measured 16 growth-trait wood-property indices these using advanced equipment, such as X-ray diffraction (XRD) Hitman ST300 standing tree tool. For traits, significant were observed between ginkgoes terms diameter at breast height (DBH), clear bole (CBH), height, volume. Significant identified degree cellulose crystallinity (DCC), cell length, wall thickness, wall-to-lumen ratio. Tracheids from found be wider, with thicker walls, than those trees. Principal component analysis (PCA) showed that there slight separation sexes all whereas no properties. membership function value (MFV) also exhibited more robust phenotype ginkgo. selection breeding offers distinct advantages practical production.

A água é um dos principais fatores para o crescimento e desenvolvimento de plantas, sendo os vasos do xilema dutos responsáveis pelo seu transporte das raízes até a parte aérea plantas. característica porta-enxerto pode influenciar formação condutores cultivares copa, bem como condutividade hidráulica da planta suprir eficiência no água. O objetivo desse estudo foi caracterizar ramos quatro genótipos Prunus ssp., utilizados porta-enxertos. Foi determinada perda percentual hidráulica, quantificando número, diâmetro frequência distribuição em cinco classes diâmetros (< 15; 15 – 30; 30 45; > 45 µm), estimando-se condutância teórica. Dentre analisados, verificou-se significativa diferença número xilema, características que determinaram uma maior teórica (Kh) ‘Montclar’, se mostrou mais suscetível efeitos embolia. ‘Capdeboscq’ apresentou média com inferior μm junto ‘Okinawa’ apresentaram as menores médias Kh PLC nos ramos. Ambos entre um, mitigando relacionados As porta-enxertos podem ter impacto significativo na capacidade importante considerar essas variáveis selecionar utilizar cultivos ssp.
