“…It has been reported in literature that particulate matter may induce damage by lowering the transpiration rate (51) and by stomata blockage with a decrease in their conductance to CO 2 (52). In the case of Cineraria , it is possible the large‐sized particulate material does not produce a harmful effect because surface hairs act as a stopping barrier and powders cannot reach stomata.…”

Optical properties of plant leaves are relevant to evaluate their physiological state and stress effect. The main objective of this work was to study how variegation, pigment composition or reflective features modifies leaves' photophysical behavior. For this purpose, green leaves (Ficus benjamina), purple leaves (Tradescantia pallida), green leaves covered by white trichomes (Cineraria maritima) and variegated leaves (Codiaeum aucubifolium) were analyzed. Firstly, foliar surface morphology was evaluated by scanning electron microscopy. UV‐vis and near‐IR reflectance and transmittance spectra were obtained to calculate absorption (k) and scattering (s) coefficients. The theoretical approaches of Pile of Plates and Kubelka–Munk's theory resulted still valid for nonstandard leaves with differing surface conditions. However, frequently used spectral indices were not reliable for predicting water content, when leaves differed from conventional ones. The proportionality between the absorption factor and chromophore/pigment concentration was also lost for hairy leaves. A simplified model to describe these facts was presented here. Fluorescence spectra were recorded and corrected, due to light re‐absorption. Water‐optical parameter connection and pigment‐optical parameter connection were thoroughly discussed. Leaf surface morphology and pigmentation have not only influenced the optical features of leaves but also played a role in the effect that particulate matter could cause on leaf photosynthesis.

This study was being elucidated in order to understand the performance of water mobilization and transpiration in oil palm tree at the age of 2, 4, and 22 years old respectively. To gain that, we attempt to collect the data in regard with the large of total leaf surface (meter square), description on transpiration rate in total leaf surface (in ml/second/cm 2 ), the number of stomata at both top and bottom leaf surface, description of root anatomy and total number of roots, water retention, and transpiration. To measure the large of total leaf surface (meter square), we calculated the large of single leaf in (m 2 ), multiply with number of leaves per midrib, and total midrib. We quantified transpiration rate in total leaf surface (in ml/second/cm 2 ) using the method of cobalt chloride, and calculated the numbers of stomata at both top and bottom leaf surface microscopically, and observed and described qualitatively the palm oil root anatomy and total number of roots. We estimated water retention via calculating the percentage of water content in root and stem. Finally, we recorded the environment data such as air humidity, air temperature and light intensity during the observations. The result showed that in average the total leaf surface at one oil palm tree is 88.77 m 2 ; 102.55 m 2 ; and 134,91 m 2 at 2, 4, and 22 years old respectively. This larges of leaf are to accomplished the transpiration at the rate of 3.38; 5.69, and 1.24 (ml/second/cm 2 ) correspondingly. The number of stomata at bottom leaf surface is bigger than the one at top surface so that the bottom surface is mostly for the place of transpiration occurrence. The number of root for water absorption per palm oil shoot is 324 in average. We illustrated that young root anatomy is more compact and as the growth and development occured, the root is more complicated into root branch and root of the root branch. As the maturation occured, the tissue of mature organ of root branch was disrupted and blessingly to become easier and more effective for water absorption. Water retention was estimated on the data of water content at root (71,70% to 73,40%) in shoot (49,45 -71,27%). In conclusion, the water mobilization in oil palm tree is a complicated, huge and very dynamics, from roots below the soil, absorbed into stem, and finally evaporated mostly into transpiration. The dynamics depend on its environment variables.

“…For efficient transpiration to take place, general freshness of leaf is critical which is lacking in particulate polluted sites. These pollutants lead to external foliar anomalies, which results in overall decline in transpiration efficiency of the stands affected by particulate pollutants 20 . Thus, the particulate pollution dust leads to reduced transpiration in the affected trees during summer season.…”

The study on teak Tectona grandis L. under particulate pollution stress caused by deposition of cement dust revealed that various physiological functions were hampered due to these pollutants. The dust accumulation was highest during summer (0.299 mg/ sq. cm) in the polluted plot in comparison to control plot (0.037 mg/sq. cm). The effects of particulate pollution on T. grandis also varied with season, with a general trend of particulate pollutants having maximum effect on vegetation during summer and least during monsoon. The rate of photosynthesis was halved due to particulate pollutant deposition. Particulate pollution decreased the water potential of T. grandis during summer. The rate of transpiration in particulate pollution-affected trees was highly erratic, being the highest during monsoon and least during summer in comparison to those not exposed to pollution. All these induced morphological changes such as reduced height, girth, etc. and also reduced the effective growing days by shedding leaves in the trees exposed to particulate pollution. Leaf area index, which is an indicator of plant productivity, was almost half in pollution-affected trees than control trees. T. grandis can serve as an effective barrier in controlling the spread of pollutants. However, it is ineffective during summer, due the deciduous nature.
