Effect of five substrates on growth indices of papaya (Carica papaya L.) plants under glasshouse conditions
In this experiment there were evaluated the effects of five substrates (peat, soil, peat + burned rice husks mixture, sand and the so-called “conventional substrate”) on the ‘Maradol’ papaya and the ‘Tainung-1’ hybrid plant growth, under greenhouse conditions, at the National University of Colombia,...

| description | In this experiment there were evaluated the effects of five substrates (peat, soil, peat + burned rice husks mixture, sand and the so-called “conventional substrate”) on the ‘Maradol’ papaya and the ‘Tainung-1’ hybrid plant growth, under greenhouse conditions, at the National University of Colombia, in Bogota. Leaf area and dry matter weight were weekly measured, from germination to 56 days after emergence (DAE) period. Leaf area index (LAI), relative growth rate (RGR), crop growth rate (CGR) and net assimilation rate (NAR) were calculated. Peat (Klasmann®), was the most suitable substrate for both materials, because provided the best physical and chemical conditions for both growth and development. Thus, results showed that plants growing on both materials showed preference to peat-moss. The ‘Tainung-1’ hybrid showed a better behavior with respect to ‘Maradol’. Finally, the plants growing on peat showed the highest CGR values with 1.34 g·cm-2·day-1 for ‘Tainung-1’ and 1.20 g·cm-2·day-1 for ‘Maradol’. Furthermore, the supply of rice husks or hen manure affected negatively leaf area and shoot development. |

Furthermore, the supply of rice husks or hen manure affected negatively leaf area and shoot development. En este experimento se evaluó el efecto de cinco sustratos (turba rubia, suelo, mezcla de turba+cascarilla de arroz quemada, arena y el denominado “sustrato convencional”) sobre el crecimiento de plantas de papaya variedad ‘Maradol’ y el híbrido ‘Tainung-1’, bajo condiciones de invernadero, ubicado en la Universidad Nacional de Colombia, Bogotá. Semanalmente se tomaron medidas de: área foliar y peso seco, durante el período comprendido entre la siembra hasta los 56 días después de emergencia (dde). Con esta información se calcularon los parámetros índice de área foliar (IAF), tasa de crecimiento relativo (TCR), tasa de crecimiento del cultivo (TCC) y tasa de asimilación neta (TAN). El sustrato más adecuado para ambos materiales fue la turba rubia (Klassman®), debido a que provee las mejores características físico-químicas para el crecimiento y desarrollo de las plantas. Las plantas del híbrido ‘Tainung-1’ tuvieron un mejor comportamiento con respecto a la variedad ‘Maradol’. Al final del ciclo, las plantas que crecieron en turba mostraron los valores más altos de TCC, con 1,34 g·cm-2·día-1 para ‘Tainung-1’ y 1,20 g·cm-2·d-1 para ‘Maradol’. Se observó que la adición de cascarilla o de gallinaza al sustrato tuvo un efecto negativo sobre el área foliar y el desarrollo del brote.
