In scenarios of climatic change when increased global temperatures can be expected,it is essential to search for technologies that favor sapling survival and growth after planting and increase yield in the ***-based particle films(KBPF)have been applied as barriers against the deleterious effects of high levels of solar *** objective of the present study was to assess the effects of applying purified calcined kaolin-based particle film to young eucalyptus *** treatments were carried out:0%(just water),3%,5%,7%,and 10%calcined kaolin applied to the adaxial part of the leaves.A complete randomized block design was used with five treatments and ten *** plants were assessed for height,diameter at ground level,gas exchanges(net photosynthetic CO_(2) assimilation,stomatal conductance and transpiration),instantaneous(WUE)and intrinsic water use efficiency(IWUE),chlorophyll a fluorescence(maximum quantum yield of photosystem II(PSII)(Fv/Fm),concentration of active reaction centers in relation to the quantity of photons absorbed(RC/ABS)and the maximum ratio of quantum yields of photochemical and concurrent non-photochemical processes in PSII(Fv/F0),SPAD reading and leaf *** 3%KBPF concentration showed the best responses in biometric assessments 80 days after planting(daP)and were corroborated by the responses of the leaf,stem and shoot dry matter production as a *** leaf ontogeny assessments showed positive responses following KBPF application when considering leaf development,with 7%KBPF concentration resulting in the highest mean *** mean specific leaf mass had negative response to high KBPF *** 60 daP,the gas exchange variables during both assessment periods declined with an increase in KBPF *** differences as a result of KBPF applications were found only at the start of the assessments(34 daP)for both WUE and for ***‘greenness’(SPAD reading)at 47 days showed a quadratic
