Coloração do Fruto e Substrato na Emergência e no Crescimento de Plantas de Eugenia calycina Cambess

Abstract

RESUMOO objetivo do trabalho foi avaliar a influência da coloração dos frutos na emergência e no crescimento das plantas de Eugenia calycina Cambess (pitangueira-do-cerrado), assim como de substratos com diferentes proporções de material orgânico e estruturante.

Fruit Coloring and Substrate in Emergence and Growth of Eugenia calycina Cambess Seedlings ABSTRACTThis study aimed to evaluate the influence of fruit coloring in emergence process and growth of Eugenia calycina Cambess seedlings, as well substrates with different proportions of organic and structuring material. Three experiments were conducted: the first of emergence; the second of plant growth, both with fruits of green color, orange/red, light red and dark red; and the third experiment was conducted to compare five mixture of Bioplant  supplemented with Vermiculita  and coconut i powder n the seedling growth, both in proportion of 20 and 40%. The fruit coloring did not influence the capacity of emergence, time (initial, mean and final), rate and synchrony of emergence of E. calycina seedlings. The growth of E. calycina seedlings is independent of fruit color up to 270 days. The Vermiculita  and -coconut powder supplemented by Bioplant  do not improved the plants growth up to 120 days of cultivation.

Substrates to produce Jambolan (Syzygium cumini) seedlings

“…The same result was observed for the use of vermiculite in detriment of sand, showing adequate physical conditions for the substrate, such as high water retention, high porosity, low density and high CEC. These results corroborate with those obtained by Borges et al (2016) who stated that Bioplant®, even supplemented with other compounds such as vermiculite and coconut powder at proportions of 20% to 40%, did not increase the height of Eugenia calycina plants. Shoot dry mass (SDM), root dry mass (RDM), and total dry mass (TDM) of the seedlings grown in substrate S9 were higher than those cultivated in substrates S3, S4, S5, S11, and S13, however not different from the remaining substrates (Table 5).…”

Estádio de maturação e repouso pós-colheita dos frutos na qualidade de sementes de pimenta biquinho

“…Já com o repouso pós-colheita, notou-se que sementes oriundas de frutos colhidos nos estádios 2 e 3 de maturação se destacaram, apresentando as maiores médias. Esses resultados corroboram com os encontrados por Queiroz et al (2011) e Borges et al (2016) que estudaram a qualidade fisiológica de sementes de pimenta habanero amarela e cereja do cerrado (Eugenia calycina Cambess), respectivamente, em associação com a coloração do exocarpo dos frutos.…”

Diferentes Substratos E Ambientes Protegidos Para O Crescimento De Mudas De Maracujazeiro Amarelo Doce

“…Alves et al (2012) relatam que, para plântulas de Crateva tapia L., submetidas à temperatura de 20 a 30ºC, a utilização Bioplant ® não propiciou desenvolvimento radicular adequado. Borges et al (2016) afirmam que, mesmo o Bioplant ® suplementado com outros compostos como a vermiculita e o pó-de-coco na proporção de 20% e 40%, não incrementou na altura de plantas de Eugenia calycina.…”
