They are influenced by the stomata and photosynthesis of the plant. The main objectives of the experiments are to determine the stomata and photosynthetic activity changes in the Dalbergia sissoo seedlings under the entisol soil in nursery conditions and the water stress conditions on AMF colonization. The plant growth characteristics and physiological activities in D. sissoo were assessed under three conditions: WW (well watering), FW (fractionated watering), and SW (stopped/no watering), with the results revealing that the FW condition has a higher mycorrhizal dependency of 24.53% than the WW condition, which is 24.37%. AMF root colonization was also higher in D. Sissoo, at 56% and 47% under FW and WW conditions. These findings highlight the significance of AMF, especially when plants are experiencing water stress. When FW was used instead of WW, the photosynthetic rate of D. sissoo and AMF + plants increased by 17.85%. AMF inoculation changed the plant’s physiological activities, resulting in a significantly higher photosynthesis rate and stomatal conductance. However, higher transpiration, intercellular CO2 concentration, and a lower leaf temperature regardless of WW or FW conditions indicate that AM positively affects physiological activities. The findings support the use of AMF in entisol soil to improve plant growth and biomass by alleviating adverse edaphic conditions.","PeriodicalId":51802,"journal":{"name":"Forest Science and Technology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73170648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study here is therefore aimed to assess the potency of teak genetic structure in Southeast Sulawesi, Indonesia. Leaf materials were sampled from six populations: the villages of Angondara, Anduna (Konawe), Napabalano, Matakidi, Wakuru (Muna) and Wakonti (Buton). One population from Java Island (Kepek) was used as an outgroup. Genetic structures were assessed by using six microsatellite markers. The genetic diversity within populations was moderate (mean expected heterozygosity = 0.544; mean allelic richness = 3.752) as well as the genetic differentiation among the populations (mean F ST = 0.085). Dendrogram analysis revealed that the populations were separated into two clusters; the first is Kepek-Angondara, Anduna-Napabalano-Matakidi, Wakuru, and the second is Wakonti. AMOVA showed that the genetic variation was insignificant between regions, but significant among populations. The structural analysis demonstrates the division of populations into two lineages (Java and Southeast Sulawesi populations). Differences in genetic structures indicated that the teak from Southeast Sulawesi may have originated from other sources. Thus, those populations are promising for broadening the genetic base of commercial teak in Java.","PeriodicalId":51802,"journal":{"name":"Forest Science and Technology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84695977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this research is to generate mathematical models for estimating the LA and LW of Cinchona officinalis leaves. A total of 220 leaves were collected from C. officinalis plants 10 months after transplantation. Each leaf was measured for length, width, weight, and leaf area. Data for 80% of leaves were used to form the training set, and data for the remaining 20% were used as the validation set. The training set was used for model fit and choice, whereas the validation set al.lowed assessment of the of the model’s predictive ability. The LA and LW were modeled using seven linear regression models based on the length (L) and width (Wi) of leaves. In addition, the models were assessed based on calculation of the following statistics: goodness of fit (R 2), root mean squared error (RMSE), Akaike’s information criterion (AIC), and the deviation between the regression line of the observed versus expected values and the reference line, determined by the area between these lines (ABL). For LA estimation, the model LA = 11.521(Wi) − 21.422 (R 2 = 0.96, RMSE = 28.16, AIC = 3.48, and ABL = 140.34) was chosen, while for LW determination, LW = 0.2419(Wi) − 0.4936 (R 2 = 0.93, RMSE = 0.56, AIC = 37.36, and ABL = 0.03) was selected.

Nevertheless, site-specific and appropriate biomass equations and root/shoot ratio are hardly available for natural larch (Larix sibirica Ledeb.) forests in Mongolia. The present study aimed (1) to develop allometric equations to estimate the above- and below-ground biomass of L. sibirica trees, and (2) to estimate the root/shoot ratio applicable for estimating the root biomass based on above-ground biomass of natural larch forests in northern Mongolia. A total of 40 trees with DBH ranging from 6.8 to 40.8 cm were sampled for tree biomass analyses. For each biomass component, we calculated the proportion of biomass allocated to different components, and also tested four allometric equations based on diameter at breast height (DBH) and height (H) as independent variables. Our results, based on measurements of oven-dried biomass, revealed that stem biomass on average accounted for 44.5% and followed by branch (28.6%) and root (19.9%) biomass, respectively. Stem and branch biomass proportions were gradually increased with increasing DBH, while a contrary trend was observed for needles. The root/shoot ratio averaged 0.25. A comparison of the allocation of root biomass by diameter fractions showed an ever-growing trend of coarse roots with an increase in stem diameter, which often exceeded more than 50% of the total root biomass. However, biomass equations, which include both DBH and H were more precise than equations that are solely based only on DBH. Consequently, among the proposed allometric regression models for estimating the AGB and BGB, the equation y = aD b H c was selected as the best-fitted equation for estimating each biomass component in Siberian larch forests. These allometric equations are available to be used for the estimation of natural larch forest biomass and carbon stocks in the Khentii Mountains of Mongolia, where extreme continental climate conditions dominate.","PeriodicalId":51802,"journal":{"name":"Forest Science and Technology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84425861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clonal propagation of Quercus suber via somatic embryogenesis is an alternative to conventional tree propagation methods. However, complete maturation of somatic embryos is considered the major bottleneck for mass propagation of Quercus suber during somatic embryogenesis. This study focuses on influences of cytokinins on secondary somatic embryogenesis. Cytokinins showed a negative effect on the induction of secondary somatic embryogenesis. For the various concentrations tested, the number of secondary somatic embryos was significantly reduced except in the case with low dose of 2iP, which showed a slight increase. Abscisic acid (ABA) may be beneficial at low concentrations between 0.3 and 0.5 mg/l. The best number of secondary embryos was given at 0.5 mg/l ABA with an average number of 5 embryos from each primary embryo, which represents a slight increase below 10% compared to control medium. Also, we found that the number of responsive embryos presenting secondary somatic embryos based on their cotyledons decreased once adding ABA. Phenylurea derivatives TDZ and DPU do not promoted the process of secondary somatic embryogenesis. DPU showed no significant effect with a similar response to that of the control medium and TDZ showed an inhibitory effect. Gibberellic acid (GA3) partially blocked the process of somatic embryos multiplication, but promoted remarkably the germination of cotyledonary embryos without requesting a particular protocol. Our results provide a new insight into embryo development, establishing the basis for further research toward improvement of secondary somatic embryogenesis in Moroccan cork oak.","PeriodicalId":51802,"journal":{"name":"Forest Science and Technology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82412665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is getting popular due to its ethnobotanical values and its potential use as host plant for lac production. Its natural population and genetic variability is declining at faster rate due to deforestation and human interventions. Mass production of Kusum seedlings is a major challenge and moreover, auto-generation of heterozygous nature in plants calls for long term experiments for its genetic improvement which require huge monetary investments. Moreover, the factors like low quality and quantity planting materials and the problem of restricted growth in plants raised from seeds hinder the interest of the farmers. Hence, clonal propagation through grafting could be an option. The scientific knowledge on application and standardization of various approaches like girdling of scionstick branches, age of mother plant, rootstocks, etc. of Kusum are extremely limited. Keeping these in view, an experiment was conducted during 2018–2021 to standardize grafting technique in Kusum. The result revealed that grafting methods affected the graft’s success significantly. Cleft grafting was found to be the most successful (72.38% graft) than veneer grafting (64.46%). Moreover, the scions collected from tree aged <15 years showed maximum success in grafting (upto 86.23%). This study revealed the importance of girdling of scionstick branches, girdling age (3 months), girdling-ring thickness (6–8 mm), and selection of two years old rootstock to maximize graft success upto 86.25% in Kusum. Furthermore, season also play an important role in successful grafting. The period from April to June was the best time for grafting with 73.31% success.","PeriodicalId":51802,"journal":{"name":"Forest Science and Technology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80802457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The SFI was based on the forest index (FI) and the concept of Dark Objects. Each SFI was compared to existing vegetation indices (ratio vegetation index, normalized difference vegetation index, leaf area index, and forest index) for forest data analysis. The highest correlation was with SFI2. The SFI2 data agreed with the national forest inventory (NFI) 2018 data. The SFI2 of the forest area was set at 1.2, which was confirmed with 90.4% confidence.

The results showed that Q. dentata germination increased by 9.4 days under climate change conditions (RCP 4.5 scenario), whereas the below-ground biomass and plant biomass increased by 1.3 and 1.2 times, respectively. However, the soil moisture treatment condition solely affected the leaf area, below-ground biomass, and plant biomass but not the germination percentage, germination speed, above-ground length, and above-ground biomass. The variance across the measured growth variables was considerably higher in the control group than in the climate change treatment group, whereas the variance was lower for lower soil moisture content. The findings suggested that under climate change conditions, Q. dentata germinated rapidly and exhibited broader leaf area and increased development below ground, which may be advantageous for the early establishment of seedlings. However, the plants may face difficulties in conditions with low soil moisture content. In conclusion, with continuous climate changes, Q. dentata seedlings are predicted to efficiently adapt to the altered soil moisture content to exhibit even more reliable growth than with the current condition. However, the growth of Q. dentata seedlings would be more difficult with severely low soil moisture content than with abundant soil moisture content, which is predicted to be detrimental to population maintenance in the long term.","PeriodicalId":51802,"journal":{"name":"Forest Science and Technology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90719360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
