The effect of neuromuscular block on the pattern of distribution of myosin isozymes in developing skeletal muscle fibers was examined by immunocytochemistry. The homogeneous population of fibers in the anterior latissimus dorsi (ALD) of the 18-day chick embryo was converted by curare to a mosaic of at least two categories of fibers. Normally all fibers in this slow muscle reacted with antibodies against slow myosin (anti-ALD). They also reacted with an antibody specific for the alkali 1 light chain (anti-A1) but not the alkali 2 light chain (anti-A2) of fast myosin. After treatment with curare, which inhibits neuronal cell death and diseases the number of axonal endings, ALD muscle fibers continued to react with anti-A1, but many now reacted with anti-A2 as well. The same fibers failed to react with anti-ALD. From this it can be concluded that the myosin in this population was converted to a type not normally present. The changes, therefore, are not merely a result of the preferencial loss of a slow type of fiber, nor are they a result of delayed maturation. In contrast, curare had no apparent effect on the fast posterior latissimus dorsi (PLD). As in the normal muscle at 18 days, all fibers reacted strongly with anti-A1 and to variable degrees with anti-A2, and veru few fibers reacted with anti-ALD. Our observations suggest that the dual response to antibodies against fast and slow myosin during development is not a necessary consequence of multiple axon terminals. We present evidence that curare induces the expressioan of a different myosin in the embryonic ALD, and we suggest that the selective transformation of the fiber population may be a manifestation of a change in composition of the motoneuron pool.

The objective of this work was to evaluate the feasibility of using ammonium thiosulfate as a chemical blossom thinner in 'Maxi Gala' apple (Malus domestica) trees and its effects on fruit quality. The experiment was carried out in an experimental orchard in the Southern Brazil, in a randomized complete block design, with five replicates. Ammonium thiosulfate was sprayed on the apple trees at the full bloom stage, at 0, 1.5, 2.5, and 3.5%. Evaluations were performed for the effects on crop load, fruit set, yield efficiency, and fruit quality parameters such as weight, shape, total soluble solids, seed number, flesh firmness, color, and russeting occurrence. Ammonium thiosulfate at 2.5% is effective to reduce crop load and to improve fruit quality. The thinning effect of ammonium thiosulfate is not dependent on the weather conditions during the crop season. The rate of 3.5% of ammonium thiosulfate causes overthinning and does not result in the improvement of fruit quality. Index terms: Malus domestica, ATS, blossom stage, flower thinning.

O experimento foi realizado em pomar experimental no sul do Brasil, em delineamento de blocos ao acaso, com cinco repetições. O tiossulfato de amônio foi aplicado às macieiras em plena floração, a 0, 1,5, 2,5 e 3,5%. Foram feitas avaliações quanto aos efeitos sobre carga de frutos, frutificação efetiva, eficiência produtiva e parâmetros de qualidade de frutos como massa, formato, sólidos solúveis totais, número de sementes, firmeza de polpa, coloração e ocorrência de “russeting”. O tiossulfato de amônio a 2,5% é efetivo na redução da carga de frutos e no aumento da qualidade dos frutos. O efeito raleante do tiossulfato de amônio não é dependente das condições climáticas durante o período de raleio. A dose de 3,5% de tiossulfato de amônio causa raleio excessivo e não resulta em melhoria na qualidade dos frutos. Termos para indexação: Malus domestica, ATS, plena floração, raleio de flores.
