“Role and Analysis of Multimedia Computing Technology in Teaching Methodologyâ€
No full textThis paper describes about the role of multimedia computing technology in teaching process. Multimedia is anything and everything that you watch and listen in a form of text, photograph, audio, video and many. This is usually recoded and played, displayed or accessed by information content processing devices such as computerized and electronic devices. In the multimedia we can use being in the business, schools, home, public places, colleges, institutes and virtual reality. These have many functions to do many things and have made the things to more mobile. Today multimedia computing is the most easy and simple way to make understand to the students. Earlier it was difficult to make understand the students about the content but now days due to multimedia computing it is very easy to describe the content to the student. Multimedia plays an important role in today's society because it is society now all are the things is keep up with the times. The multimedia is a good way for communication because that can easy to communicate and understand what they say
Physiological behavior of greenhouse-grown chrysanthemum (Chrysanthemum morifolium ´’Shrek’ ´ and ´Bomber Green´) in response to the plant growth retardant B-9 and the cytokinin BAP
No full textilustraciones, diagramas, fotografías, tablasEl crisantemo (Chrysanthemum morifolium Ram) representa la tercera flor de corte de
importancia económica en el mercado internacional. En el presente estudio, se caracterizó
la respuesta de plantas de crisantemo ‘Shrek’ y ‘Bomber Green’ y la vida de florero de
tallos cortados, a la aplicación del retardante de crecimiento B-9 (daminozida) y la
citoquinina (6-benciladenina, BAP). En un primer ensayo se evaluó la aplicación de B-9,
con un testigo absoluto sin adición de B-9 y un testigo comercial (TC), usando 6
concentraciones diferentes aplicadas a los 28, 36, 44 y 52 días después del trasplante
(DDT). En un segundo ensayo, se evaluó la aplicación de la citoquinina (CK) BAP (0, 33,3,
66,6 y 100 mg kg-1
) suministrada a los 28, 36, 44 y 52 DDT. La respuesta a estos
tratamientos fue evaluada con una cuantificación de la masa seca acumulada en órganos
(raíz, tallo, hojas y flores) y cálculos de algunos parámetros de crecimiento. Se determinó
el índice de clorofilas con medidor portátil SPAD-502 en hojas del estrato bajo, medio y
superior. Se caracterizó también la duración en días de la vida en florero, inicio de
amarillamiento y grado de amarillamiento de las hojas. La aplicación de B-9 generó una
reducción en la altura de la planta. El cultivar ‘Shrek’ tuvo diferencias estadísticas (P<0,05)
en la acumulación y en parámetros de crecimiento relacionados con el área foliar. La
acumulación de masa seca fue mayor en tallos de los dos cultivares. Con aplicación de
CK, el índice de clorofila incrementó en los estratos medio y superior, mientras que, en las
hojas del estrato inferior disminuyó y se presentó amarillamiento del follaje. La mayor vida
en florero se obtuvo en tallos de ‘Bomber Green’. Los factores que promueven el
amarillamiento del follaje podrían estar relacionados con el material vegetal y la interacción
con las condiciones ambientales a las cuales se expongan las plantas durante el crecimiento y desarrollo (Texto tomado de la fuente).The chrysanthemum (Chrysanthemum morifolium Ram) represents the third cut flower of
economic importance in the international market. The present study characterized the
responses of chrysanthemum plants ‘Shrek’ and ‘Bomber Green’ to the application of the
growth retardant B-9 (active ingredient daminozide), and the addition of the citokinin 6-
benzyladenine (6-BAP) on the chlorophyll content and vase life of cut flower stems. The
first trial evaluated the application of seven concentrations of B-9 applied at 28, 36, 44 and
52 days after transplant (DAT). A second trial evaluated the application of three
concentrations of 6-BAP supplied at 28, 36, 44 and 52 DAT. Dry mass accumulation in the
various plant organs (roots, stems, leaves and flowers) were evaluated along with
calculation of some growth parameters. The chlorophyll index was determined with a
SPAD-502 portable meter in leaves of the lower, middle, and upper third of plants. Finally,
the duration in days of vase life and the onset and degree of leaf yellowing were
characterized in the two cultivars. The application of B-9 caused a reduction in plant height
and the cultivar ‘Shrek’ had statistical differences (P<0.05) in biomass accumulation and
growth parameters related to leaf area. Dry mass gain was greater in stems of the two
cultivars. With CK application the chlorophyll index increased in the middle and upper
leaves, while in the leaves of the lower third had lower values and yellowing symptoms.
The longest vase life was observed in flower stems of ‘Bomber Green’. The factors that
promote the yellowing of the foliage could be related to plant genetics and its interaction
with environmental conditions during the crop growing cycle.MaestríaMagíster en Ciencias AgrariasFisiología de Cultivo
