This research designs three machine learning systems, namely a vanilla CNN model, a CNN-SVM hybrid model, and a MobileNetV2-based transfer learning model that detect yellowed and scorched leaves in Catharanthus roseus and strawberry plants, respectively, using images captured by ...
We calculate the probability of “Desert plants”, “Conifer” and “Macrophyte” from the archived plant waxes in the late Pleistocene sediment core. We then validate the models by comparing reconstructions of vegetation from the plant wax molecular abundance distributions in downcore samples to ...

Arctic ecosystems hold large stocks of potentially labile soil C and are dominated by plants with high root: shoot ratios. However, simple models of Arctic tundra ER typically use only aboveground drivers, such as air temperature and leaf area index. To investigate this apparent discrepancy, we ...

A pine tree isany coniferfrom thePinusgenus of plants, and this group includes more than 120 types of pine trees worldwide. These are evergreen conifers,woody plantsthat bear seed cones and which have bundles of needles rather than the broad leaves commonly found on deciduous trees. ...
All plants were well watered until they reached the V3 stage (3 fully expanded leaves with the fourth one emerging) before imposing drought stress by cessation of watering. Osmotic and drought stress treatments Eight days after subculturing, sorghum cell suspension cultures were exposed to osmotic ...
Identification of anthracnose resistant strawberry germplasm has commonly relied on inoculation of whole plants with isolates of these pathogens. In this study, whole plants and detached leaves from 81 germplasm lines were inoculated with a conidial suspension of isolates of C. acutatum, C. fragariae,...
Which structure is found mainly in green plants and bacteria? What were some issues with the study of early marine bacteria? What distinguishes animals from other eukaryotes? What characteristics do algae share with plants? What are the characteristics of annelids?
