“…Models using D as the sole independent variable had high R² and low RMSE, indicating a robust intrinsic relationship between D and biomass, making it a key parameter in biomass models. Other studies have shown that the regression model for D. clearness using the single compound predictive variables DH (model 1) was the most robust (Nogueira et al, 2021). Tree height (H) is usually added as a second parameter in biomass models to improve estimation accuracy, but previous studies have shown varying effects of H on model accuracy.…”

China has long been the world's largest producer of pine resin. Pinus massoniana Lamb. It is a significant afforestation and timber species in southern China, accounting for more than half of the forest stock in southern China， It proliferates, with high resin yield, making it an essential component of forestry operations south of mountainous areas and a pillar industry in forestry. However, studies on the impact of resin tapping on biomass allocation and height-diameter allometric growth dynamics of Pinus massoniana are unclear. This study focused on Pinus massoniana plantations in the South Subtropical Region of Guangxi to explore the effects of resin tapping on biomass allocation patterns and allometric growth relationships. Whole-tree harvesting was used to collect samples, with diameter at breast height, tree height, and ground diameter as essential variables to construct allometric biomass models suitable for Pinus massoniana forests under resin tapping disturbance. We constructed allometric growth models for aboveground and belowground parts and between organs to reveal the best biomass models and predictive variables. The results showed that resin tapping disturbance significantly reduced the biomass of various organs in Pinus massoniana, with reductions in stem, bark, root, aboveground, and total biomass statistically significant (P<0.05). However, the changes in leaf and branch biomass were insignificant (P>0.05), indicating that the impact of resin tapping is selective among different organs. The goodness-of-fit of allometric growth models showed that models for resin-tapped Pinus massoniana had better fit than those for non-resin-tapped trees. In the developed and tested regression models, except for leaf biomass and root biomass models, the remaining models achieved acceptable performance statistics. Models for stem, bark, and aboveground biomass performed best (models 4, 4, and 7). These models have critical applications in forestry management, providing scientific evidence for biomass estimation and management of Pinus massonianaplantations under resin tapping disturbance.

Cashew plants are generally evergreen, so they cover land throughout the year, have a dome-like canopy shape and thick leaves are thought to reduce CO2 emissions, one of the gas that triggered global warming that likely turn into climate change. The research aims to measure carbon stocks and reduce CO2 gas emissions in cashew nuts has been carried out in Pondok Village, Wonogiri, Central Java, one of the cashews growing centers in Indonesia. The method of determining plant samples was carried out on cashew crops by monoculture, the age groups (KU) were differentiated 1, 2, 3, 4 and 5, the measuring plots were determined purposively due to the limited population in the same age plot. Carbon stocks were analyzed using the allomeric method, while CO2 emissions were calculated descriptively. The results showed that cashew plants have the ability to increase carbon stocks and reduce CO2 gas emissions, this ability is kuadratic in line with plant KU. The highest carbon stock by KU 4 plants, the highest ability to reduce CO2 emissions is found in plants aged 30-40 years. The implications of research results on crop management related to emission reduction and increase in C-stock are discussed.
