| slow photosynthetic induction and low photosynthesis in paphiopedilum armeniacum are related to its lack of guard cell chloroplast and peculiar stomatal anatomy. | paphiopedilum and cypripedium are close relatives in the subfamily cypripedioideae. cypripedium leaves contain guard cell chloroplasts, whereas paphiopedilum do not. it is unclear whether the lack of guard cell chloroplasts affects photosynthetic induction, which is important for understory plants to utilize sunflecks. to understand the role of guard cell chloroplasts in photosynthetic induction of paphiopedilum and cypripedium, the stomatal anatomy and photosynthetic induction of paphiopedilum ... | 2011 | 21241312 |
| mycorrhizal specificity, preference, and plasticity of six slipper orchids from south western china. | mycorrhizal fungi of six endangered species, paphiopedilum micranthum, paphiopedilum armeniacum, paphiopedilum dianthum, cypripedium flavum, cypripedium guttatum, and cypripedium tibeticum, from two closely related genera in the orchidaceae from southwestern china, were characterized using the nuclear internal transcribed spacer (its) and part of the large subunit gene of mitochondrial rdna (mtlsu) sequences. the most frequently detected fungi belonged to the tulasnellaceae. these fungi were rep ... | 2010 | 20217434 |
| photosynthetic performance along a light gradient as related to leaf characteristics of a naturally occurring cypripedium flavum. | photosynthesis, leaf structure, nitrogen content and nitrogen allocation in photosynthetic functions of cypripedium flavum were studied in a naturally varying light regime. light-saturated leaf net photosynthetic rate (a max) was strongly correlated with leaf dry mass per area (lma), mesophyll conductance (g (m)) and area-based leaf nitrogen content (n area), with all variables increasing with increasing irradiance. such coordinate variation of all these parameters illustrates the plastic respon ... | 2008 | 18807119 |
