The techniques for measuring Hevea laticiferous turgor pressure which have been reported are summarized. The commonly used three methods used for measuring Hevea laticiferous turgor pressure have their limitation in deep and systematic observation of the variation of Hevea laticiferous turgor pressure and are not involved in the study of the variation of laticiferous turgor pressure under the normal ethrel stimulated tapping system. A possibility of using an improved cell pressure probe method which has been recently established for other plants is discussed in accurate measurement of the real time variation of Hevea laticiferous turgor pressure.

In the paper, the multidentate carboxylic acid ligands were used to combine with Cd, resulting in the three dimensional MOCPs single crystals—C12H16CdN2O8, with a low temperature hydrothermal synthesis method. The sample was characterized with IR spectra to affirm the organic groups in the frameworks, single-crystal X-ray diffraction to determine the crystal structure and composition of the frameworks, N2 adsorption isotherms at low temperature to measure the specific surface area and pore size distribution, and with TGA/DGA analysis to scale the thermal stability. Furthermore, the dissolution property and the photocatalytic activity of MOCPs under the ultraviolet ray condition were explored.
