The temperature is one of the climatic factors of greater importance in the physiological processes of the plants, being directly related to its growth and development, which need a thermal accumulation to complete its phenological cycles. The objective of this work was to evaluate the contribution of temperature to cacao tree seedlings (genotype TSH1188) development, thus determining its lower basal (Tb) and upper (TB) temperature as well as the thermal sum in degree-day (DD) required for its production with quality. The study was carried out in the Horticulture sector of the Federal Institute of Espirito Santo - Campus Itapina, Colatina/ES, conducted under a completely randomized design in three planting seasons with different climatic conditions. For the estimation of Tb, four different estimation methods were used: standard deviation in degree-day (SDdd), the standard deviation in days (SDd), the coefficient of variation in degree-day (CVdd) and relative development (RD). The upper basal temperature (TB) was estimated similarly to Tb, with the exception of the RD method. The basal temperatures (Tb and TB) were estimated by means of the average values obtained in the methods used and the thermal sum, obtained in each planting season, using the mean Tb value, from the emergence of the seedlings, by the sum of the degree-days. The estimated values of lower and upper basal temperature were respectively 10°C and 37°C and the mean thermal sum for a quality cacao tree seedling production is 1018°C. In order to obtain a production of quality cacao tree seedlings in different climatic conditions, it is possible to evaluate the development of the variables height, stem diameter and number of leaves of the cacao tree seedlings as a function of accumulated degrees. The time required for the production of cacao tree seedlings varies according to the season of the year. Cacao tree seedlings conducted in periods with higher temperatures took less time to form with quality.

Utilizando-se quatro cultivares de laranjeiras (Citrus sinensis (L.) Osbeck), realizou-se um estudo no pomar da Escola Superior de Agricultura de Lavras - ESAL -, visando determinar suas épocas e intensidades de florescimento, bem como o pegamento de frutos segundo seus quadrantes. Foram avaliados o número de dias necessários para atingir 70% do florescimento, número total de flores e percentagem de pegamento de frutos. Os resultados demonstraram a maior precocidade da cultivar Baianinha, seguida pela Pera Rio, Valência e Natal. O quadrante Sul apresentou maior precocidade de florescimento, enquanto no Norte ocorreu o maior número de flores. Não houve diferença entre as cultivares em relação ao número total de frutos.
Four orange cultivars (Citrus sinensis (L.) Osbeck), grown in the orchard of Escola Superior de Agricultura de Lavras (ESAL), state of Minas Gerais, Brazil, were studied in order to establish their blooming season and blooming intensity, as well as the number of grown fruits according to their quadrants. The number of days necessary to attain 70% of blooming, the total number of flowers, and the percentage of grown fruits were evaluated. It was concluded that the cultivars 'Baianinha' was the earliest variety, íoliowed by 'Pera Rio', 'Valência' and 'Natal'. The southern quadrant had the earliest blooming, whercas the northcrn one had more fiowers. No differences were found among the cultivars as for the
total number of fruits. |
