Copernicia prunifera belongs to the Arecaceae family, and its production chain includes a set of economic activities based on the use of the stipe, petiole, fiber, fruits, roots, and leaves from which carnaúba wax is extracted, an economically valuable resource in the region. This study aimed to evaluate the uses, management, and perception of the species by local extractors. Two communities were studied, Bem Quer, where 15 extractors of carnaúba leaves were interviewed, and Cana, where 21 extractors considered specialists were interviewed, totaling a sample of 36 interviewees. Interviewees were asked questions about uses, ways of handling, and perception of morphological variation in the carnaúba leaves. The number of leaves extracted and the income obtained from the sale of leaves were estimated from interviews and notes that each leader of extractors held during the year of the research and previous years, as well as direct observations made by researchers in the communities which recollection area of straw hold about 80 thousand individuals of C. prunifera. A regression analysis was used to explore the relationships between social variables (age, time in extractive activity, and income obtained from extraction) with the number of leaves exploited. The leaf was indicated as the most used part, from which an important powder is extracted for the production of wax. In addition, the leaf was also indicated to be used for fertilization and construction. The relationship between the socioeconomic variables, income from extraction, and the number of leaves extracted (in thousands) was significant (R2 = 0.73 and p < 0.001). However, the other variables analyzed in this study, such as the time spent extracting leaves and the years of residence in the community (R2 = 0.03 and p > 0.05); the number of leaves extracted and interviewee age (R2= 0.05 and p > 0.05); and the number of leaves extracted and extraction time (R2 = 0.04 and p > 0.05) did not indicate a relationship. Local extractors observed that new leaves have the highest sales value, as they have the highest production of powder. In addition, economic factor is the preponderant force that directs the management strategies of native species. For this species, however, morphological and genetic studies are needed for further clarification.

在巴西热带稀树草原的农村社区中使用,感知和管理哥白尼(Miller)HE Moore

Copernicia prunifera属于Arecaceae家族,其生产链包括一系列经济活动,该活动基于使用柄,叶柄,纤维,果实,根和叶的方法,从中提取了巴西棕榈蜡,这是该地区的一种经济上有价值的资源。 。这项研究旨在评估本地提取者对该物种的使用,管理和感知。对两个社区进行了研究,Bem Quer对15个巴西棕榈叶提取物进行了采访,而Cana对21个被认为是专家的提取物进行了采访,总共对36名受访者进行了抽样调查。受访者被问到有关巴西棕榈叶用途,处理方式和形态变化感知的问题。通过访谈和摘录估计了提取的树叶数量和从出售树叶中获得的收入,并指出,在研究年度和前几年,每个提取者负责人都曾担任过,并在回收地区的社区中对研究人员进行了直接观察。的秸秆可容纳约8万株修剪的C. prunifera。使用回归分析来探索社会变量(年龄,提取活动的时间以及提取所得的收入)与所利用的叶子数量之间的关系。叶被指示为最常用的部分,从中提取出重要的粉末以生产蜡。此外,还表明该叶可用于施肥和施工。社会经济变量,提取收入,并且提取的叶子数量(以千计)很显着(R2 = 0.73和p <0.001)。但是,在这项研究中分析的其他变量,例如花叶提取的时间和在社区中的居住年限(R2 = 0.03,p> 0.05);抽出的叶子数量和受访者的年龄(R2 = 0.05,p> 0.05);提取的叶片数和提取时间(R2 = 0.04,p> 0.05)之间没有关系。当地的提取者观察到,由于新叶片的粉末产量最高,因此其销售价值最高。此外,经济因素是主导本地物种管理策略的主导力量。但是,对于该物种,需要进一步的形态学和遗传学研究。001)。但是,在这项研究中分析的其他变量,例如花叶提取的时间和在社区中的居住年限(R2 = 0.03,p> 0.05);抽出的叶子数量和受访者的年龄(R2 = 0.05,p> 0.05);提取的叶片数和提取时间(R2 = 0.04,p> 0.05)之间没有关系。当地的提取者观察到,由于新叶的粉末产量最高,因此其销售价值最高。此外,经济因素是主导本地物种管理策略的主导力量。但是,对于该物种,需要进一步的形态学和遗传学研究。001)。但是,在这项研究中分析的其他变量,例如花叶提取的时间和在社区中的居住年限(R2 = 0.03,p> 0.05);抽出的叶子数量和受访者的年龄(R2 = 0.05,p> 0.05);提取的叶片数和提取时间(R2 = 0.04,p> 0.05)之间没有关系。当地的提取者观察到,由于新叶的粉末产量最高,因此其销售价值最高。此外,经济因素是主导本地物种管理策略的主导力量。但是,对于该物种,需要进一步的形态学和遗传学研究。03和p> 0.05);抽出的叶子数量和受访者的年龄(R2 = 0.05,p> 0.05);提取的叶片数和提取时间(R2 = 0.04,p> 0.05)之间没有关系。当地的提取者观察到,由于新叶的粉末产量最高,因此其销售价值最高。此外,经济因素是主导本地物种管理策略的主导力量。但是,对于该物种,需要进一步的形态学和遗传学研究。03和p> 0.05);抽出的叶子数量和受访者的年龄(R2 = 0.05,p> 0.05);提取的叶片数和提取时间(R2 = 0.04,p> 0.05)之间没有关系。当地的提取者观察到,由于新叶的粉末产量最高,因此其销售价值最高。此外,经济因素是主导本地物种管理策略的主导力量。但是,对于该物种,需要进一步的形态学和遗传学研究。因为它们的粉末产量最高。此外,经济因素是主导本地物种管理策略的主导力量。但是,对于该物种,需要进一步的形态学和遗传学研究。因为它们的粉末产量最高。此外,经济因素是主导本地物种管理策略的主导力量。但是,对于该物种,需要进一步的形态学和遗传学研究。
