“…Several studies of rooting in vermiculite have shown that with this substrate the larger size is reached in all variables: stem diameter, stem height, wet and dry weight of whole plant dry weight of shoot and root weight dry the main root and secondary roots dry weight. In addition, rates have been evaluated to determine the quality of the plant, which showed vermiculite substrates for the best behavior (Di Benedetto et al 2002;Olivo & Buduba, 2006).…”

Colombian flower growers are faced with economic and social problems, so they are looking for alternatives, which include Proteas, ornamentals that require research that ensures an appropriate, local technical management. One of the Proteas most likely to be involved in this search is the genus Leucadendron. Therefore, this study aimed to establish the best basis for rooting its cuttings. The experimental design was a split plot design with a factorial arrangement. Four substrates were evaluated in combination with two auxins, naphthaleneacetic acid (NAA) and indolebutiric acid (IBA), three doses each, plus a commercial control. Each treatment was repeated three times and the experimental unit consisted of 30 stakes at the first locality and 25 at the second one. The most relevant results showed that vermiculite was the best substrate for rooting cuttings of Leucadendron at both localities. Also, it was identified that IBA is the growth regulator which improved the rooting percentage, the root volume, the stem decreased the percentage of losses.

“…el peso seco de la parte aérea (vástago) y peso seco de la raíz se obtuvieron mediante el secado de las hojas (incluyendo el pecíolo), tallo y raíz en estufa de aire forzado a 68 °C por 48 h. La suma del peso seco de las hojas y del tallo dio como resultado el peso seco del vástago. Los índices morfológicos relación entre el peso seco de la parte aérea y peso seco de raíces, y el índice de calidad de Dickson (ICD) también se calcularon (Olivo & Buduba, 2006). Este último se estimó mediante la siguiente relación:…”

“…In addition to the above, the dry weight of the aerial part (shoot) and dry weight of the root were obtained by drying the leaves (including the petiole), stem and root in forced air oven at 68 °C for 48 h. The sum of the dry weight of the leaves and stem resulted in the dry weight of the shoot. The morphological indices ratio between dry shoot weight and dry root weight, and the Dickson quality index (ICD) were also calculated (Olivo & Buduba, 2006). The latter was estimated by the following relation:…”

L a producción de orégano en vivero es una opción para la obtención de plantas de buena calidad para trasplante. El propósito del presente estudio fue evaluar el efecto de cinco sustratos y cinco contenedores en el crecimiento y calidad de la planta de orégano. Los sustratos fueron: mezcla comercial BM2 (turba, perlita y vermiculita, 80:10:10), BM2 + arena de río (1:1), BM2 + arena de río (1.5:1), BM2 + perlita + vermiculita (1:1:1) y mezcla de composta + arena de río (1.5:1). Los contenedores incluyeron charolas de poliestireno expandido (PE) de 200, 128 y 76 cavidades, vaso de PE de 250 cm3 y bolsa de plástico negro de 712 cm3 (calibre 150 μm). Se usó un diseño experimental de bloques al azar con arreglo factorial, con cuatro repeticiones por tratamiento. Los sustratos y el tipo de contenedor afectaron el crecimiento y calidad de la planta. Se observó mayor crecimiento de la planta y mayor área foliar en la combinación bolsa y sustrato BM2. Este mismo sustrato y el contenedor bolsa promovieron el índice de calidad de Dickson más alto. La relación peso seco del vástago y peso seco de la raíz fue mayor en los contenedores de mayor volumen.

“…With the ideal substrate mix for a crop, one can therefore provide the optimal environment for the growth of an extensive root system [21,22]. The citrus plant root system is limited, which results in a poor capacity for nutrient absorption [23].…”

Abstract:In Puerto Rico, oranges made up $6,452,000 of the agricultural gross income for 2014-2015. Today, citrus greening (CG) is the most aggressive disease affecting the citrus industry in the whole world. This disease causes dieback of the plant, among other symptoms, which is resulting in the reduction of citrus trees in the field across the world. Currently, it is recommended to grow citrus rootstocks in nurseries to produce disease-free trees. The objective of this investigation was to evaluate (before and after grafting) the effect of different substrate mixes and quantities of fertilizers on the rootstocks Carrizo citrange and Swingle citrumelo in order to accelerate their development inside of a protected structure. The treatments were: Promix + sand (control) (1:1), Promix + sand + coco peat (1:1:1), Promix + sand + coffee compost (1:1:1) and Promix + sand + rice husk (1:1:1). Two 18-6-2 fertilizer treatments were also evaluated: 5.6 g and 8.5 g. The substrate that contained 33% rice husks negatively influenced every parameter evaluated for both rootstocks. Carrizo presented better development on the coffee compost mix, while Swingle did not exhibit significant differences among any substrates, except on rice husk, for most of the parameters. "Rhode Red Valencia" presented better results for dry weight when grafted on Carrizo with the coffee substrate. The rice husk substrate is not recommended for the citrus tree production at the nursery level.
