Potassium Nutrition Affects Leaf Growth, Anatomy, and Macroelements of Guzmania [PDF]

open access: yesHortScience, 2008
Guzmania lingulata (L.) Mez. ‘Cherry’ plants were grown in coconut husk chips. All plants were given 8 mm nitrogen (N), 2 mm phosphorus (P), 4 mm calcium (Ca), and 1 mm magnesium (Mg) at each irrigation with potassium (K) concentration at 0, 2, 4, or 6 mm.

Modeling the Population Demographics & Viability of Imperiled Guzmania monostachia Populations

open access: yesSPORA: A Journal of Biomathematics, 2023
Guzmania monostachia is a large, long-lived bromeliad whose leaves grow in a rosette pattern and is native to the Americas, but endangered in Florida due to damage caused by the invasive weevil Metamasius callizona. Each G. monostachia rosette can reproduce sexually via flowers or asexually by producing clonal offshoot rosettes. We model the population

Chloroplast Acclimation in Leaves of Guzmania monostachia in Response to High Light [PDF]

open access: yesPlant Physiology, 1999
Abstract Acclimation of leaves to high light (HL; 650 μmol m−2 s−1) was investigated in the long-lived epiphytic bromeliad Guzmania monostachiaand compared with plants maintained under low light (LL; 50 μmol m−2 s−1). Despite a 60% decrease in total chlorophyll in HL-grown plants, the chlorophyll a/bratio remained stable.

Feasibility study on mental health‐care effects of plant installations in office spaces

open access: yesJAPAN ARCHITECTURAL REVIEW, Volume 2, Issue 3, Page 376-388, July 2019., 2019
This paper focuses on the mental health‐care effects of plant installation in office spaces. To clarify the effect of indoor plants, we conducted a demonstration experiment in two rooms of an office. In the experiment, nine cycles were conducted while changing the type of plants including vegetables and foliage plants.
