Chimonobambusa sp. "Suijiang"

Specimen: BS-0749 [SSG] (living plants), raised from seeds collected from 绥江 (Suijiang), northern Yunnan, China. The seeds obtained from FMXG, Yunnan, China, as "Qiongzhuea sp. from Suijiang, 绥江筇竹 (suí jiāng qióng zhú)", collected April/May 2012, and received 12 May 2012.

Seed viability: Rather short, 2–3 weeks under normal atmospheric conditions, or 1–2 months under very low temperatures above freezing point. Seeds need to be stored in humid conditions and should not dry out. If affected by mold, a fungicide solution treatment prior to sowing is needed (e.g., 5 g Carbendazim in 2 l water, seeds to be soaked for 1–2 hours). — acc. FMXG.

Seed weight: 10 g ≈ 20–30 humid seeds, mixed, husk-wrapped seeds, and those bare of husks.

Seed germination: Seeds (BS-0749) laid in moistened coir dust, in May 2012, 27–33 °C day, diffuse light, 22–25 °C night, atmospheric humidity 60–85%, the first coleoptiles emerged after 9 days.

Comments: (1) Seeds are somewhat bigger than those of Chimonobambusa tumidissinoda. — (2) The seedlings were distributed in northern Thailand, but the current locations of the cultivated plants are unknown.
