The gladiolus stands out among the cut flowers cultivated in Brazil, as soon as it presents ease of cultivation and rapid financial return. However, its growth and productivity can be altered as a result of changes in the meteorological elements. This study investigated the vegetative growth of the gladiolus submitted to different shading environments in Serra Talhada -PE. The experiment was conducted at the Academic Unit of Serra Talhada \UFRPE, from June 28 to September 1, in a completely randomized design in three cultivation environments, full sun (control), under black shading 70% (sombrite) and 70% thermo-reflector(aluminet). The Amsterdam variety (Gladiolus x hortullanus L), cultivated in polyethylene containers with a volume of nine liters, was filledwith soil, sand and vermiculite (2: 1: 1) and three bulbs per container. Biometric parameters were evaluated: plant height, number of leaves, neck diameter, and biomass: leaf dry mass, dry mass of the bulb and dry mass of the root. In addition, meteorological elements were monitored: air temperature, relative air humidity, radiation and wind speed. The highest values in relation to plant height occurred in the treatment with 70% shade. There was no influence of the use of the shading screens for the number of leaves, neck diameter and root dry mass. The use of the thermo -reflector provided a greater accumulation of dry mass of the leaves at the end of the experimental period and favored the process of releasing the nutritional demand of the bulbs to theaerial part, more efficiently than the other growing environments. The screens provided reduced temperature, increased relative humidity, marked reduction in global solar radiation, and reduced wind speed. RFA values were higher in the thermo-reflector environment when compared to the sombrite environment.

Passion fruit (Passiflora edulis Sims.) is a dicot of great socioeconomic importance in Brazil and the largest producer and consumer of passion fruit in the world. The crop is widely explored in the Northeast, where it generates significant income, especially for small and medium-sized fruit growers, especially family farmers. Among the factors responsible for the success of passion fruit crops is the quality seedling, especially with the use of adequate substrate. The properties presented by the substrates are variable, and the type of substrate affects the development and root system of the plant, as well as the supply of nutrients, consequently the emergence and development of the seedling. There are few researches regarding the appropriate substrate to be used in the production of passion fruit seedlings in the Northeast region, mainly works in this direction can help the producers of family agriculture in this region. The objective of this work is to evaluate different substrates in the development of passion fruit seedlings BRS Rubi do Cerrado in the Sertão of Pernambuco. The research was carried out under greenhouse conditions with 50% shading at the Serra Talhada Academic Unit of the Federal Rural University of Pernambuco, in the municipality of Serra Talhada, PE. The experimental design adopted was completely randomized, with four treatments (substrates: washed sand, fine-grained vermiculite, coarse-grained vermiculite and coconut fiber), five replications, using 10 plants per plot. The data obtained at 98 days after sowing were submitted to analysis of variance and the means were compared by Tukey's test, at a 5% probability level. The coconut fiber substrate provided better development of the shoot and root system of the passion fruit seedlings BRS Rubi do Cerrado, with greater stem diameter and dry mass, greater fresh and dry mass of the leaves, greater dry and fresh mass of the root, providing obtaining better quality seedlings, with a higher Dickson quality index.
