Effect of substrates for in vitro germination of mahogany (Swietenia macrophylla King); Efeito de substratos na germinação in vitro de mogno (Swietenia macrophylla King)

Abstract

The objective of this work was to verify the effect of substrates and different light conditions and temperature on in vitro germination of mahogany (Swietenia macrophylla King) seeds for the production of explants for the initialprocess of micropropagation. In the first experiment the seeds were inoculatedintwosubstrates: 7gL{sup -1} agar and vermiculite,maintained at temperature of 25±1°C with photoperiod of 16 hours and 52 mmol m{sup -2} s{sup -1}irradiance. MS medium supplementedwith sucrose (10; 20; and 30g L{sup -1}) was used. For the second experiment the seeds were submitted to light conditions (presence and absence)and temperature (25 and 30 °C) and inoculated in MS medium supplementedwith 30g L{sup -1} sucrose +vermiculite. The vermiculite was more efficient than agar as substrate for the in vitro seed germination of mahogany. The MS medium, supplemented with 30g L{sup -1} sucrose + vermiculite, was more efficient for the in vitro seed germination of mahogany. The temperatures of 25 and 30 °C independent of the presence or absence of light had no influence in the number and time for the in vitro germination of these seeds.

No primeiro experimento, as sementes foram inoculadas em dois substratos: ágar a 7g.L{sup -1} e vermiculita, e mantidas em temperatura de 25±1°C sob fotoperíodo de 16 horas de luz e 25 mmol.m{sup -2}.s{sup -1} de irradiância. O meio de cultura utilizado foi o MS, suplementado com sacarose (10; 20; e 30g.L{sup -1}). Para o segundo experimento, as sementes foram submetidas às condições de luz (presença e ausência) e temperatura (25 e 30 °C), sendo utilizado o meio de cultura MS com 30g.L{sup -1} de sacarose + vermiculita. A vermiculita foi superior ao ágar como substrato para a germinação de sementes de mogno in vitro. O meio MS adicionado de 30 g.L{sup -1} de sacarose + vermiculita foi o mais eficiente na germinação de sementes de mogno in vitro. As temperaturas de 25 °C e 30 °C, independentemente da presença ou ausência de luz, não influenciaram no número e tempo de germinação in vitro dessas sementes. (author)}
