En la Región Sur del Ecuador se comparó la producción de avena (Avena sativa L.) y trigo (Triticum vulgare L.) obtenida a partir de un sistema de forraje verde hidropónico (FVH), frente al sistema de producción convencional o a campo abierto (CA). El experimento para cada sistema y cultivo se estableció bajo un diseño de bloques al azar, instalando cuatro tratamientos (dos en FVH y dos a CA), con tres repeticiones cada uno. Se evaluó la altura de la planta (AP) de cada cultivo para cada sistema productivo, mientras que para cada sistema y cultivo se determinó la producción de biomasa, la proteína cruda (PC) (p < 0,05) y el cociente de la relación beneficio-costo (B/C). La mayor altura se obtuvo en trigo FVH con 17,67 cm y en avena CA con 82,78 cm. En relación con la producción de biomasa, el trigo FVH alcanzó 23,57 kg/m2 de materia verde (MV) o 3,10 kg/m2 de materia seca (MS); el resto de tratamientos estuvo por debajo de 13 kg/m2 de MV (1,39 kg/m2 de MS); el porcentaje de proteína en el trigo CA fue mayor con 19,90 %, seguido de avena CA, mientras que el trigo y la avena FVH tuvieron valores de alrededor del 10 %; en beneficio-costo, el trigo FVH obtuvo un puntaje mayor de 1,46 frente a la avena FVH (0,67), el trigo CA (0,26) y la avena CA (1,00). Por esta razón, la complementariedad de los dos sistemas de producción, especialmente en el cultivo de trigo, podría ser una opción para la alimentación animal.

Molar Basis

The phytotoxic monoterpenes, camphor, pulegone, and borneol, exhibit a marked synergistic action when used in combination. On a molar basis, these phytotoxic concentrations are enhanced from 40 to 100 times by using two compounds simultaneously. The toxicity of these compounds is about the same for radish (Raphanus sativus L.) and wheat (Triticum vulgare Vill.) but is less by an average of tenfold for oats (Avena sativa L.). When the compounds are used singly, they are from 3 to 12 times as effective in inhibiting root elongation as they are in inhibition of germination.

Hermetia Illucens Larvae

A by-product of protein production from the larvae of the black soldier fly ( Hermetia illucens ) is a zoocompost consisting of a variety of organic compounds. The purpose of the work was to determine the hazard class of the zoo complex - the waste of cultivation of Hermetia illucens larvae using biotesting methods, since the use of calculated methods to determine the hazard class is difficult. Biotesting experiments were carried out on test organisms: planktonic crustacean Daphnia magna , algae Chlorella vulgaris , seeds of Avena sativa , Triticum vulgare and Hordeum sativum . It has been established that the zoocompost refers to low-risk waste. Extractions of the zoocompost stimulate the growth of plants Avena sativa and Hordeum sativum , it is supposed to be used as a phytostimulator. It has been shown that an environmentally friendly wasteless method for the production of protein additive from insects is possible.

In attempting to use the SEM to investigate the transition from the vegetative to the floral state in oat (Avena sativa L.) it was discovered that the procedures of fixation and critical point drying (CPD), and fresh tissue examination of the specimens gave unsatisfactory results. In most cases, by using these techniques, cells of the tissue were collapsed or otherwise visibly distorted. Figure 1 shows the results of fixation with 4.5% formaldehyde-gluteraldehyde followed by CPD. Almost all cellular detail has been obscured by the resulting shrinkage distortions. The larger cracks seen on the left of the picture may be due to dissection damage, rather than CPD. The results of observation of fresh tissue are seen in Fig. 2. Although there is a substantial improvement over CPD, some cell collapse still occurs.Due to these difficulties, it was decided to experiment with cold stage techniques. The specimens to be observed were dissected out and attached to the sample stub using a carbon based conductive paint in acetone.

E Objetivo: Desarrollar un procedimiento para estimar biomasa con imágenes digitales captadas desde un dron y modelación 3D (ID-Dron-3D) aplicable en alfalfa (Medicago sativa L.) y avena forrajera (Avena sativa L.). Diseño/metodología/aproximación: Con una cámara digital acoplada al dron se obtuvieron imágenes antes de la cosecha de los cultivos, que fueron procesadas con software para luego estimar volumen de biomasa. En cada cultivo se midió altura de la planta y área cosechada, volumen aparente y real de biomasa, y peso de biomasa fresca y seca. Resultados: Con base en el análisis de regresión se obtuvieron modelos lineales a una p<0.05 para predecir: biomasa fresca en avena (R2=0.70) y alfalfa (R2 =0.47); y biomasa seca en avena (R2=0.78) y en alfalfa (R2=0.31) mediante ID-Dron-3D. Limitaciones del estudio/implicaciones: Considerando las R2 de los modelos obtenidos, los resultados en la avena forrajera fueron mejores, respecto a los detectados en alfalfa, lo cual se puede deber a la mayor variabilidad de la cobertura vegetal, ya que, en algunas unidades de muestreo, las plantas de alfalfa no cubrían completamente el suelo. Hallazgos/conclusiones: El rendimiento de biomasa fresca y seca de ambos cultivos se correlacionó significativamente con su respectivo volumen aparente estimado con imágenes digitales tomadas desde un dron y su procesamiento 3D (ID-Dron-3D).

Introduction. Lipids are a widespread group of biologically active substances in nature, making up the bulk of the organic substances of all living organisms. They accumulate in plants in seeds, as well as in fruits and perform a number of vital functions: they are the main components of cell membranes and the energy reserve for the body.Aim. Study of neutral lipids of sown oats (Avena sativa L.).Materials and methods. The objects of the study were fruits (grains) of oats of the sown variety "Tashkent 1," harvested in the Republic of Uzbekistan. Results and discussions. Neutral lipids of oat grains have been found to contain 13 fatty acids with a predominance of the sum of oleic, linolenic and linoleic acids. The total degree of unsaturation was almost 78%. Absorption bands characteristic of these substances were observed in the IR spectrum of MEGC.Conclusion. According to the results of the NL analysis, oat grains consisted of triacylglycerides and free LCDs, which were accompanied by hydrocarbons, phytosterols, triterpenoids and tocopherols.

ABSTRACT The presence of oestrogen inhibitory activity in oat hay (Avena sativa) and Fahli clover hay (Trifolium alexandrinum var. Fahli) has been established. The antioestrogenic effect was demonstrated by the inhibition of uterine weight increase in rats (Astwood test) in response to oestradiol injected together with the above mentioned plant extracts. The extraction procedures are described in detail and the possible biological implications of antioestrogenic and oestrogenic activity in fodder plants is discussed.
