As teachers, we must know about the physical developmental processes our students are experiencing. These are reflected in behaviour, emotions and relationships. And for adolescents, who are trying hard to figure out how the world operates, the physical changes they experience have a potent impact on their world view. While the sequencing of much of our physical development is pretty well according to a grand template and rolls out in much the same way from one person to the next, not everything occurs in a set way (Richter, 2006). Some aspects of our physical development cause other things to occur and are tied together. For example, hormonal changes during puberty are tied to the development of secondary sexual characteristics. However, there is individual variation at multiple levels, and we will discuss these. To complicate things, adolescents’ feelings and ideas about themselves and the ways in which they interact with the world as they grow and change are coloured by our societies’ multifaceted sets of ideals, standards and expectations for physical development. Many other things also impact on our conceptions of self and these will be discussed when we turn our attention to the development of identity through adolescence. In this chapter we will present some basic information about the types of physical changes to expect during adolescence, and consider some challenges that confront adolescents during this time of development.

In order to study the efficiency of aldicarb against aphids, beneficial arthropods, and on cotton physiology, a trial was made at Jaboticabal, SP, Brazil, in 1992/93. The experimental design was a complete randomized block with seven replications and three treatments: 1) aldicarb 750 g of a.i./ha; 2) aldicarb 1050 g of a.i./ha; and 3) control. The results showed that aldicarb was effective in the control of aphids. Aldicarb applied in the furrow significantly increased boll number per plant, yield, and precociousness. The beneficial arthropods were not affected.

This investigation was conducted between June and September, in an experimental area, whose coordinates are latitude 21°15'22 south and longitude 48°18'58 east, situated at a mean altitude of 575 m. The soil of the area is classified as Red Latossolo (Commission of Soils, 1960), Haplorthox soil. The effects of two cultivation systems: protection with nonwoven polypropyleno and in an open field, on broccoli cultivars 'Baron', 'Shigimori', 'Pinacco' were evaluated. The experiments were a randomized block experimental design, using a factorial arrangement of 3 (cultivars) x 2 (cultivation systems), with four replicates. The characteristics evaluated were precociousness, longitudinal and transverse diameters of broccoli heads, fresh mass of broccoli heads and number of leaves per plant. The 'Baron' cultivar was more precocious, having its harvest at 86 days after transplanting in both cultivation systems. 'Baron', despite being more precocious, had inferior results in relation to the other cultivars. The open field cultivation system was optimum for cultivars 'Shigimori' and 'Pinacco'.

La división de matas es una técnica de propagación difundida con gran éxito entre las Gramíneas. Cuando se trata de la producción comercial de este grupo de plantas, es importante conocer la época en que se realiza esta práctica para obtener plantas de la mejor calidad en el menor tiempo posible. Según algunos autores, la estación apropiada para dividir gramíneas está relacionada con el momento de activo crecimiento: primavera tardía para las especies estivales y otoño o primavera temprana para las invernales. En este trabajo se estudió la influencia de la época del año en la división de matas de Miscanthus sinensis "Variegatus", Miscanthus sinensis "Zebrinus", Miscanthus sinensis "Morning Light", Paspalum haumanii, Leymus arenarius, Pennisetum setaceum y Trichloris crinita en diciembre y febrero. Se evaluaron las características ornamentales y la precocidad, con fines comerciales, de las plantas obtenidas en otoño y primavera tardía. Las variables utilizadas fueron altura vegetativa, diámetro de canopia y de corona, número de cañas y porcentaje de sobrevivencia. Desde el punto de vista comercial y productivo, es conveniente realizar la división de matas en otoño para obtener precocidad sólo en M. sinensis "Variegatus" y M. sinensis "Zebrinus". En el caso de M. sinensis "Morning Light", P. setaceum, T. crinita, P. haumanii y Leymus es más adecuada la división de primavera.
