“…According to Küster et al (2018), values for length and width of the "D" leaf are strongly influenced by both genotype and environment, and they should not be used as quality indicators of pineapple fruit 'Vitória'. Pineapple leaf show a high plasticity, changing its morphological characteristics to optimize the use of environmental resources (Cheng et al, 2018).…”

The objective of this work was to evaluate the effect of shoot types and plant ages for floral induction on the performance of 'Vitória' pineapple (Ananas comosus). The experiment was carried out from April 2015 to December 2016, using shoots of two different classifications (slips of 100 to 200 g and suckers of 201 to 300 g). Artificial floral induction was performed at the eighth, tenth, and twelfth months after planting, and natural induction was also evaluated. Evaluations for vegetative development, phenology, and productivity were performed. A significant interaction was observed between the studied factors for width and area of the “D” leaf. Shoot type did not influence productivity. Natural flowering extended the crop cycle by 617 days. The induction performed at the eighth month anticipated harvest by up to 167 days. Earlier inductions reduced productivity by 58.15% due to the reduction of fruit mass. Naturally induced plants produced larger fruit ranging from 1.0 to 1.2 kg. Inductions from the eighth to the tenth month promote harvesting in more favorable seasons.

The objective of this study was to evaluate the influence of macronutrient and boron deficiencies on physico-chemical characteristics of pineapple fruits, ‘Vitoria’ cultivar. The experimental design was a randomized complete block with eight treatments (complete solution, -N, -P, -K, -Ca, -Mg, -S and -B) and six replicates. The experiment was conducted from October 2016 to March 2018, and the variables evaluated were: fresh fruit and crown mass, fruit diameter, fruit and crown length, juice volume and mass, titratable acidity (TA), soluble solids (SS), vitamin C, juice pH and SS/TA ratio. All treatments with nutrient deficiency reduced the fresh fruit mass. In treatments -N and -Ca there was a reduction of 41.9 and 35.3%, respectively, in the crown fresh mass. Fruits diameter under N, K and Mg deficiency was lower, fruit length, soluble solids and juice pH were lower in treatment with N deficiency. Isolated deficiencies of each of the macronutrients and B reduced the mass of the whole fruit and the crownless fruit. The nutrient that most limited the size and quality of ‘Vitoria’ pineapple fruit was nitrogen.

Salinity is a recurring abiotic stress in arid and semi-arid regions, which negatively affects the establishment and growth of plants, however, the cultivation of ornamental species such as celosia argentea can tolerate saline conditions. The objective of this work was to evaluate the emergence and seedling growth of Celosia argentea cultivated under different electrical conductivities of irrigation water. The experiment was carried out in a greenhouse, in the month of July 2021. The experimental design was completely randomized with five treatments and four replications. The treatments were five electrical conductivities of irrigation water (ECw), being: 0.5; 1.5; 2.5; 3.5 and 4.5 dS m-1. They were analysed the emergence variables (percentage of emergence, average emergence time, average emergence velocity and emergence velocity index) and the growth variables (seedling height, number of leaves, stem diameter, primary root length, shoot dry weight and root dry weight) at seedling start. Moderate salinity improves seed vigor, increasing the percentage of C. argentea seedlings that emerge, culminating in satisfactory initial growth. The electrical conductivity ECw 2.5 dS m-1 is the salinity threshold that keeps the salinity-tolerant C. argentea species above the threshold and becomes sensitive to salts.
