Streszczenie:

Autonomous analysis of plants, such as for phenotyping and health monitoring etc., often requires the reliable identification and localization of single leaves, a task complicated by their complex and variable shape. Robotic sensor platforms commonly use depth sensors that rely on either infrared light or ultrasound, in addition to imaging. However, infrared methods have the disadvantage of being affected by the presence of ambient light, and ultrasound methods generally have too wide a field of view, making them ineffective for measuring complex and intricate structures. Alternatives may incl

Streszczenie:

The determination of plant nitrogen (N) content (%) in wheat via destructive lab analysis is expensive and inadequate for precision farming applications. Vegetation indices (VI) based on spectral reflectance can be used to predict plant N content indirectly. For these VI, reflectance from space-borne, airborne, or ground-borne sensors is captured. Measurements are often taken at the canopy level for practical reasons. Hence, translocation processes of nutrients that take place within the plant might be ignored or measurements might be less accurate if nutrient deficiency symptoms occur on the

The regeneration of roots and shoots through leaf cuttings is a feasible technique for plant clonal propagation, using a quite available organ, which can be collected without great damage to the plant. A protocol of propagation through leaf cuttings was defined to Piper carniconnectivum, a plant whose compounds have great potential use in medicine and agriculture. Leaves were cut in halves (apical and petiolar) by transverse cutting in the middle of the leaf blade. The petiolar parts were immersed into a solution of indole 3-butyric acid (IBA) at 1000 ppm for 30 seconds, or not submitted to th

The effects of plant age, leaf age, and leaf position on race-nonspecific resistance against Phytophthora infestans were investigated in a series of field and controlled environment experiments with five different potato (Solanum tuberosum) cultivars. Leaf position proved to be the most significant factor; apical leaves were far more resistant to late blight than basal leaves. Plant age and leaf age had only minor effects; therefore, the resistance of a specific leaf remained about the same during its entire lifetime.

Abstract In 1999, Daniel Simberloff and Betsy Von Holle introduced the term 'invasional meltdown'. The term and the concept have been embraced and critiqued but have taken a firm hold within the invasion biology canon. The original formulation of the concept argued two key points: first, biologists rarely study how non-natives interact with one another. Second, nearly all the conceptual models about the success and impact of invasive species are predicated on the importance of competitive interactions and an implicit assumption that non-natives should interfere with establishment, spread and i

The Providence Water Supply Board (PWSB) serves more than 600,000 people and maintains a pH of 10 through the treatment plant and water distribution system. Maintaining a pH of 10 results in a calcium carbonate precipitation potential (CCPP) of 5 to 12 mg/l expressed as calcium carbonate. Theo

A typical helicopter drive system consists of a multi-stage gearbox with highly loaded dynamic components such as gears, shafts, and bearings, crucial for safe flight and landing. Planetary reduction stages are commonly used in the final reduction stage of rotorcraft main gearboxes due to their ability to handle high torques at high gear ratios within a compact envelope. The planet gear, a critical component in this arrangement, is subjected to significant loads on both flanks of its teeth and must meet stringent weight and assembly requirements, leading to a thin rim design with integrated be

Abstract The performance of Hura crepitans mediated Ag (silver) nanoparticle material on the inhibition of microbes (including six bacteria and a fungus strain) inducing microbiologically-influenced-corrosion (MIC) of metals was investigated in this paper. Leaf-extract was obtained from the Hura crepitans for use as a precursor for the Ag-nanoparticle synthesis, which was then characterised by the instrumentation of scanning electron microscopy and energy dispersive spectroscopy (SEM+EDS). The natural plant-mediated Ag-nanoparticle material was then utilised for sensitivity and/or resistance e

Hemileia vastatrix, causal agent of coffee leaf rust (CLR), is an aggressive, economically devastating pathogen of coffee plants worldwide. Coffee leaf rust was discovered in Hawai‘i in 2020 and quickly spread throughout the state. Hawai‘i’s coffee industry, produced commercially on six islands by over 1,470 growers on more than 10,000 acres, is conservatively valued at $100M per year. Conventional fungicides have played a major role in the suppression of CLR, but due to a recent shift toward eco-friendly farming practices, additional novel, effective, and sustainable strategies for CLR contro

Abstract In this paper, the bubble migration characteristics of LFR after SGTR accidents are investigated based on the DPM. Firstly, the geometric and mesh models of the primary coolant system of the LFR are established, and the drag coefficient model of bubbles in the DPM is validated based on the bubble terminal velocities. Secondly, steady-state simulation of the primary coolant system of the LFR are performed to determine the temperature and velocity fields. Thirdly, the migration characteristics of the single bubble released from different positions of the SG are investigated, and the res

Background Transplanting vegetable seedlings to final spacing in the greenhouse is common practice. At the time of transplanting, the transpiring leaf area is a small fraction of the ground area and its cooling effect is rather limited. A preliminary modeling study suggested that if water supply from root to canopy is not limiting, a sparse crop could maintain about the same canopy temperature as a mature crop, at the expense of a considerably higher transpiration flux per leaf (and root) area. The objectives of this project were (1) to test the predictions of the model, (2) to select suitable

Calcium signaling has been implicated in transducing signals from environmental changes into adaptive responses in plants. Calmodulin (CaM), members of the EF-hand family of Ca2+-binding proteins, represent important relays in plant calcium signals.

Ethylene is a plant hormone that controls many plant responses, such as growth, senescence, ripening, abscission and seed germination. Recently, 1-methy- cyclopropene (1-MCP), was shown to bind to ethylene receptor for a certain period of time and prevent ethylene action. The objectives of this research were to synthesize analogues of 1-MCP and test their potency to block the ethylene receptor and inhibit ethylene action. During the course of this project, procedures for synthesis and shipment of the cyclopropene compounds were developed as well assay procedures for each compound were worked o

Age dependent programs are responsible for the physiological and developmental differences of young and mature plants. These include a range of morphological characters such as leaf shape and leaf composition (waxes, lignin etc..) but also different in developmental potentials. Apical buds of juvenile plants are vegetative, while those of mature plants can be reproductive. Likewise, basal buds form in the axills of juvenile leaves have different fates than distal buds formed in the axils of mature leaves. The goal of our joint project is to understand and exploit theses age related programs fo

The COP9 signalosome (CSN) is an eight-subunit protein complex that is highly conserved among eukaryotes. Genetic analysis of the signalosome in the plant model species Arabidopsis thaliana has shown that the signalosome is a repressor of light dependent seedling development as mutant Arabidopsis seedlings that lack this complex develop in complete darkness as if exposed to light. These mutant plants die following the seedling stage, even when exposed to light, indicating that the COP9 signalosome also has a central role in the regulation of normal photomorphogenic development.

Background to the topic: Early tomato fruit development is executed via extensive cell divisions followed by cell expansion concomitantly with endoreduplication. The signals involved in activating the different modes of growth during fruit development are still inadequately understood. Addressing this developmental process, we identified SlFSM1 as a gene expressed specifically during the cell-division dependent stages of fruit development. SlFSM1 is the founder of a class of small plant specific proteins containing a divergent SANT/MYB domain (Barg et al 2005). Before initiating this project,
