“…The rhizome acts as a spacer and is an important vascular system for physiological integration of clonal plants [13,14]. The rhizome of moso bamboo (Phyllostachys edulis) acts as a spacer for resource sharing between cloned ramets of P. edulis [15]. In a heterogeneously distributed resource environment, the P. edulis rhizome system plays an important role in transporting water, photo-assimilates, and carbohydrates under a source-sink gradient [16][17][18].…”

Water is crucial to plant growth and development. Under heterogeneous environmental water deficiency, physiological integration of the rhizomatous clonal plant triggers a series of physiological cascades, which induces both signaling and physiological responses. It is known that the rhizome of Phyllostachys edulis, which connects associated clonal ramets, has important significance in this physiological integration. This significance is attributed to the sharing of water and nutrients in the vascular bundle of clonal ramets under heterogeneous water conditions. However, the physiological characteristics of physiological integration under heterogeneous water stress remain unclear. To investigate these physiological characteristics, particularly second messenger Ca 2+ signaling characteristics, long-distance hormone signaling molecules, antioxidant enzyme activity, osmotic adjustment substance, and nitrogen metabolism, ramets with a connected (where integration was allowed to take place) and severed rhizome (with no integration) were compared in this study. The vascular bundle structure of the rhizome was also observed using laser confocal microscopy. Overall, the results suggest that interconnected rhizome of P. edulis can enhance its physiological function in response to drought-induced stress under heterogeneous water deficiency. These measured changes in physiological indices serve to improve the clonal ramets' drought adaptivity through the interconnected rhizome.

“…As for many bamboo species, there is a lack of data on quantitative pit characteristics. Compared with the 0.9~2.7 μm wide inner pit apertures and the 1.1~3.8 μm wide outer pit apertures in moso bamboo, the widths of the inner and outer pit apertures in the sympodial bamboo species in this study was remarkably narrower 8 . In comparison to the data on pit size in wood species, the measurement of pit apertures in sympodial bamboo species had a smaller range than both hardwoods and softwoods.…”

“…Previous researchers paid more attention to the relationship between the macrostructures and physical and mechanical properties of bamboo, while few detailed studies were undertaken on the anatomical features of the bamboo culm especially regarding microstructures such as the vessel elements and pits 8–11 . The structure of bamboo is considerably different from that of wood 12 .…”

The anatomical morphologies of vessel elements and pits of bamboo plants are unique, however, intensive research about vessel elements and pits in bamboo species is very scarce. The vessel elements and pits of four sympodial bamboo species were analyzed by light microscopy and environmental scanning electron microscopy (ESEM). Results show that the length and width of vessel elements were significantly different across bamboo species. The simple (main type), scalariform, and reticulate perforation plates were discovered on the end of vessel elements. The four species also displayed distinct pit forms. Characteristics of vessel elements, perforation plates, and the shape and size of pit apertures were examined separately for their potential relationship of bamboo structure and function.

“…Similarly to other monocarpic, monopodial genera of Bambuseae Shibata, 2012, 2014;Matsuo et al, 2014) Phyllostachys are monocarpic, and reproduce mainly vegetatively (Isagi et al, 2016) from nodal shoots developing from the underground rhizome system (Ito et al, 2015) which comprises 39-57 % of the total biomass (Umemura and Takenaka, 2014). Phyllostachys edulis (syn.…”

Neményi et al. : The effect of water availability on shoot and culm properties of a developing Abstract. A three year experiment was carried out on sandy soil with a vegetatively propagated single clone of Phyllostachys iridescens in Gödöllő, Hungary to investigate the effect of water availability on the number of developing and aborted shoots and the number, diameter and height of culms in a newly planted grove. Part of the experimental plot was provided with drip irrigation and irrigated 3 times a week during the vegetation period from April until the end of October in all years. The first experimental year (2010) was a moist year, while during the second (2011) and third year (2012) there was drought during spring and summer. The number of shoots that developed into culms did not significantly increase over the years in unirrigated control plants, while in irrigated plants there was a three to four fold increase in culm recruitment compared to initial values. There was no significant difference between treatments in culm diameter and culm height during the first two experimental years. However, there was a five fold significant difference in these parameters in the last year. We found a strong (R 2 =0.90, P=0.001) correlation between culm diameter and culm height. Our results prove that water supply during the growing season is of vital importance to developing temperate bamboos.
