Comparación de la biomasa de dos cultivares de papa (Solanum tuberosum L.) de distintos orígenes, plantados en Chirgua, estado Carabobo, Venezuela
Bibliographic record
Abstract
espanolLa biomasa, en cultivos como la papa (Solanum tuberosum L.), es la muestra de todo el potencial de fotosintesis y acumulacion de asimilados de la planta. En el periodo de enero- abril de 2009, se evaluo el efecto sobre el desarrollo de la biomasa de dos variedades de papa procedentes de Argentina y Canada, que se utilizan en las siembras comerciales en Chirgua, estado Carabobo. Se utilizo un diseno de bloques al azar con arreglo factorial 2x2, cultivares “Kennebec” y “Atlantic” y las dos procedencias. Semanalmente se evaluo la formacion de la biomasa aerea y de los tuberculos, relacionandola con el tiempo de crecimiento, ademas de estimar el indice de crecimiento del cultivo (ICC) y de cosecha (IC). Para obtener la biomasa las plantas fueron muestreadas y seccionadas en sus diferentes organos. Se realizaron analisis de varianza y comparacion de medias, mediante la prueba de Tukey. Se obtuvo la distribucion de la biomasa y el numero de organos durante el desarrollo del cultivo. La biomasa y numero de organos mostraron diferentes comportamientos asociados a su origen, a los cultivares y sus relaciones. El ICC fue en incremento y presento variaciones. El IC no presento diferencias. La biomasa total vario entre 114 y 1322 g m-2, y se asocio a la calidad de la “semilla”, procedencia y edades diferentes, que influyeron en el crecimiento de las plantas. EnglishThe biomass crops such as the potato ( Solanum tuberosum check for this species in other resources L.), is the sign of the potential of photosynthesis and accumulation of assimilates in plants. In the present study evaluated the effect on the development of the biomass of two potato varieties, from Argentina and Canada and which are used in commercial crops, in Chirgua, Carabobo state. The design of the experiment was blocks at random with 2 x 2 factorial arrangement, the cultivars Kennebec and Atlantic and the two origins. Weekly, assessed the formation of aerial biomass and tubers, relationship it with the time of growth. The rate of growth of the crop (RGC) and harvest index (HI) were estimated. The plants were harvested and sectioned in its different bodies, for their biomass. Analysis of variance and mean comparisons, using Tukey's test were carried out. The distribution of biomass and the number of organs during development of the crop were obtained. Biomass and number of organs showed different behaviors that depended on the origin, the cultivar and its relationship. The CRG was to increase and with variations. HI did not present differences, due to the low leaf area. Total biomass ranged between 114 and 1322 g m-2, is also associated with the quality of the seed, origin and different ages, influencing the growth of plants.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
