Ten microliters of 0.1 M β-ocimene (Sigma-Aldrich Co.) was applied onto a cotton swab, which was then hung in a glass jar (3-L) containing a Chinese cabbage plant. Given that the β-ocimene, we used dissolved in CH₂Cl₂, we used CH₂Cl₂ treated plants as controls. Plant treated with water only were used as negative controls. Twenty-four hours later, these treated plants were used for the investigation.

Comparative Analysis of Tillandsia xiphioides Ecotypes

Check if the same lab product or an alternative is used in the 5 most similar protocols

All the flowers of T. xiphioides studied in this report come from the
Tillandsia PROD plant nursery located in the commune of Le Cailar
(Occitania, France). The plant nursery includes about 500,000 Tillandsia,
of 350 species, varieties, forms, and hybrids. T. xiphioides is known to present many ecotypes differing on pubescence from lepidote
mentose with dense wolly hairs, among other characteristics.²³ For the PCA, two forms of T.
xiphioides called in this paper Low-Pubescent T. xiphioides (LP-xiphi) and High-Pubescent T. xiphioides (HP-xiphi) according to, respectively,
weak and strong morphological development of trichomes on the leaves,
were used (see Figures S1 and S2 in Supporting Information). A total of 10 plants of each form providing 2–3
flowers each were harvested from February to May 2020.
All chemicals
were purchased from Sigma-Aldrich (St. Louis, USA): α-pinene
(98.5% purity), sabinene (75%), β-pinene (98.5%), β-myrcene
(90%), limonene (99%), eucalyptol (99%), β-ocimene (95.4%),
γ-terpinene (98.5%), β-linalool (97%), α-terpineol
(90%), geraniol (99%), geranyl acetate (99%), and nerolidol (98.5%).
All have an analytical standard grade except for sabinene.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
