Monocot Dicot Plants Anatomy: Root Stem Leaf

Apr 05, 2022 The stem's interior structure is similar to that of most monocots' internal structure. Pseudobark is the tissue of the hypodermis and epidermis of the stem that is found outside the central cylinder of the stem. Dicot Stem: Cactus stem. The cactus stem is a modified dicot stem with fleshy tissue that allows it to store enormous amounts of water.

Leaf (Ψ leaf ) and stem water potential (Ψ stem ) are the most significant physiological indicators, capable of monitoring and identifying plant water status (Taylor et …

Functional relationship between leaf/stem pseudobulb size ...

Mar 09, 2022 Water storage has been commonly cited as an important function of orchid pseudobulbs, and it is reasonable to assume that orchids which utilize crassulacean acid metabolism (CAM) photosynthesis have larger pseudobulbs than those of C 3 orchid taxa, because these foliar (or stem) structures may reflect another type of succulent tissue in CAM …

Isotope signature of maize stem and leaf and investigation ...

Mar 31, 2021 Leaf water isotopic composition and isotope enrichment may contain information on the transport pathways within and beyond the plant-stem xylem (Barbour et al., 2017). Gradients in isotope enrichment of leaf water may vary with the different water movement pathways between leaf evaporating surface and the vein (Barbour and Farquhar, 2004).

Frontiers Modeling Stem Water Potential by Separating ...

Measuring seasonal plant water status is critical in choosing appropriate management strategies to ensure yields and quality of agricultural products, particularly in a context of climate change. Water status of grapevines is known to be a key factor for yield, grape composition, and wine quality. Predawn leaf water potential (PLWP) and stem water potential (SWP) proved to be …
