Size and vigor of Anadenanthera colubrina (Vell.) Brenan seeds harvested in Caatinga areas

Abstract: -Angico is a species found in several environments in Brazil, with several applications. It is used in the timber industry and mainly in folk medicine. In order to verify a variation in the biometric characteristics and the quality of seeds from different mother-plants in different harvesting years, the following variables were studied: moisture content, diameter, density, electrical conductivity, fresh and dry matter of seedlings, germination percentage and kinetics, in a completely randomized design with a 2… Show more

“…As sementes de tamanho pequeno, médio e grande, apresentaram grau de umidade 9,2; 9,4 e 10,1% respectivamente, indicando que o equilíbrio higroscópico apresentou diferença entre os tamanhos. Alves et al, (2005), também verificaram diferenças no teor de umidade de sementes de Mimosa caesalpiniifolia classificadas em classes de tamanho, entretanto, a diferença de umidade entre as sementes não compromete os resultados dos testes fisiológicos, uma vez que, é inferior a 2%, como estabelecido pela literatura (MARCOS-FILHO, 1999 (ALVES et al, 2005;MTAMBALIKA et al, 2014;MISSANJO & MAYA, 2015;MISSANJO & MKWEZALAMBA, 2015;BISPO et al, 2017), e essa relação entre o tamanho de sementes e a porcentagem de plântulas normais é variável com o local de coleta (ALVES et al, 2005;SOUZA et al, 2017), com a idade da planta matriz (BISHT et al, 2016), com as condições ambientais entre os anos de coleta (BISPO et al, 2017) e não necessariamente o tamanho das sementes.…”

“…Evidence of a positive association between seed mass and mean time to germination was observed by Norden et al [13] in an analysis of 1037 tropical tree species. Bispo et al [6] reported direct interference of seed size in seedling development of Anadenanthera colubrina, with larger seeds yielding higher growth. Evaluating the capacity of seed fragments of Eugenia pyriformis to produce new seedlings, Pratavieira et al [14] observed a significantly higher capacity by larger seeds.…”

“…Seed sizing is a single technique suggested to be an efficient indicator positively correlated with seed physiological quality and plantlet vigor [5,6]. Adams and Thielges [7] reported a weak positive correlation (r = 0.21) between seed size and seedling height in wild C. illinoinensis.…”

“…High-quality seedlings are essential in establishing healthy and productive orchards, and studies on new technologies for pecan (Carya illinoinensis (Wangenh) K. Koch) cultivation in subtropical regions have mostly focused on seedling production [33,34]. However, seed sizing is a single technique suggested as an efficient indicator positively correlated with seed physiological quality and plantlet vigor [35,36]. In this context, this study evaluated the correlation between seed mass, seed emergence and plantlet vigor in the pecan cultivar Importada, towards producing healthy seedlings for orchard establishment under subtropical climatic conditions.…”
