“…Several factors including narrow distribution range, restricted habitat preference, small population size, limited genetic diversity, slow growth rate, and reproductive system of the generative type are associated to the vulnerability of medicinal plants in response to exploitation pressure ( Chen et al., 2016 ). In fact, K. odoratissima is a high-demand medicinal plant with narrow ecological niche, weak reproductive ability, and lack of broad wings for very effective long-distance seed dispersal ( Mozaffarian, 2003 ; Ahmadi et al., 2021 ). Although regeneration of plants from root is the major determinates of population size of K. odoratissima , the recruitment of new individuals from successful seed germination is necessary for long term persistence of natural populations.…”

“…Our observations revealed that habitats for K. odoratissima were confined to some fragmented, independent, and narrow ranges in alpine regions of Zagros. The plant has disappeared from numerous historical sampling locations as a result of excessive exploitation, grazing, and land cleanup ( Ahmadi et al., 2021 ). Moreover, due to their seed dormancy, low germination rate, and inherently poor regeneration ( Ahmadi et al., 2021 ), the population size and population density of K. odoratissima has significantly decreased in recent years ( Jahantab et al., 2015 ).…”

Kelussia odoratissima Mozaff. (Apiaceae) is a native plant that has been traditionally consumed in Iran’s food and pharmaceutical industries. Overharvesting of the taxon, especially at the beginning of the growing season, due to its considerable medicinal and economic value, is believed to be the main reason for the extirpating of this plant. The consequences of the severe anthropogenic impacts on the genetic diversity of populations are poorly known. In order to investigate the level of genetic variation and patterns of the genetic structure of K. odoratissima, we developed novel microsatellite markers using the 454 Roche next-generation sequencing (NGS) platform for the first time. Out of 1,165 microsatellite markers bioinformatically confirmed, twenty-five were tested, of which 23 were used to screen genetic variation across 12 natural populations. Our results showed that the average number of alleles per locus and the polymorphic information content (PIC) were 10.87 (range 7 to 27), and 0.81 (range 0.67 to 0.94), respectively. The mean observed and expected heterozygosities (± SD) across all populations were 0.80 ± 0.31 and 0.72 ± 0.14, respectively. The average pairwise FST among the populations was 0.37 (range 0.04 to 0.81). Bayesian and distance-based clustering, and principal coordinate analyses revealed at least four major genetic clusters. Although high level of structure can be explained by landscape topography and geographic distance, presence of admixed populations can be associated to seed or pollen dispersal. Contrary to expectations, the high level of genetic variation and lack of inbreeding suggest that overexploitation has not yet significantly purged the allelic variability within the natural populations in protected areas.

“…Estudos identificaram e quantificaram várias classes de compostos presentes em extratos vegetais, como compostos fenólicos e terpenos, que mostraram efeitos promissores no tratamento de sementes (ORZALI et al, 2020) Estes métodos podem melhorar a germinação das sementes e aumentar o estabelecimento de populações de plantas, contribuindo para a restauração da função do ecossistema (AKDAĞ; TUNCER, 2020). No entanto, mais pesquisas são necessárias para identificar tratamentos mais eficazes e otimizar a germinação e o desenvolvimento das plântulas (AHMADI, 2021).…”

A dormência é um fator primordial para o sucesso da germinação das sementes de Senegalia polyphylla principalmente devido a problemas com a germinação e por ataque de besouros. Objetivou-se avaliar métodos alternativos de superação de dormência, como tratamentos com água quente, extrato do licor pirolenhoso (ELP) e óleo essencial (OE), a fim de testar a eficiência na germinação de sementes de Senegalia polyphylla, além de verificar incidência de fungos. As sementes testadas foram coletadas de três árvores matrizes em uma fisionomia de Cerrado, Gurupi-TO. O extrato do licor pirolenhoso (ELP) foi obtido a partir da carbonização da madeira do gênero Eucalyptus spp., no laboratório de Tecnologia e Utilização de Produtos Florestais I e o Óleo Essencial (OE) foi extraído das folhas da espécie Xylopia frutescens, no laboratório de Fitopatologia, Campus Universitário de Gurupi-TO. A maior germinação ocorreu para os tratamentos água a 50 °C e ELP a 5%, ambos com uma porcentagem de 98%. O controle e a água a 50 °C do ELP a 5% foram mais promissores para o índice de velocidade de germinação. Para as plântulas normais, a água a 50 ºC permitiu 94% de plântulas viáveis. Sementes não germinadas foram mais evidentes no tratamento com OE. Foi observada baixa incidência de fungos com a aplicação do OE nas sementes de Senegalia polyphylla. Extrato do licor pirolenhoso a 5% e a água a 50 ° C são métodos alternativos para a superação de dormência das sementes de Senegalia polyphylla, enquanto o óleo essencial de Xylopia frutescens é uma proposta alternativa ao controla da de fungos.
