Abstract
Seedlings production is one of the most important stages of the production system and directly influences the performance of the plant in the field. In this sense, the present work aims to evaluate the use of biomass doses of Spirulina platensis and Scenedesmus sp. via root system on the production of yellow passion fruit seedlings. A greenhouse experiment was carried out using a randomized block design in a 2 × 5 factorial scheme (Spirulina platensis and Scenedesmus sp., at the doses 0.0%, 0.2%, 0.4%, 0.8 % and 1% m/v), with four blocks and two experimental units per plot. At 60 days, leaf number, total seedling length, shoot diameter, root system length, shoot length, shoot and root fresh mass, dry mass, root dry mass and total chlorophyll were measured. Spirulina platensis showed superior performance compared to Scenedesmus sp., for the variables stem diameter, shoot length, fresh shoot mass, fresh root mass, dry shoot mass and root dry mass. The doses influenced the number of leaves, root fresh mass, root dry mass, shoot length and fresh shoot mass significantly. The best dose of microalga applied was 0.8% in passion fruit seedlings at 60 days.
Highlights
Brazil is the world’s leading producer and consumer of passion fruit, occupying a prominent position in the world market
The experiment was conducted in a greenhouse at the Center for Science and Technology Agro-Food (CCTA) of the Federal University of Campina Grande (UFCG), Campus Pombal-PB, from September to December 2017
According to Oliveira, Góes, Costa, and Silva (2011), the use of extracts based on Ascophyllum nodosum in the production of yellow passion fruit seedlings provided a significant increase in the number of leaves as the doses were increased up to the estimated value of 4.05 ml/L of the compound, above this value there was a decrease
Summary
Brazil is the world’s leading producer and consumer of passion fruit, occupying a prominent position in the world market. The present work aimed to evaluate doses of Spirulina platensis and Scenedesmus sp., via root system on the production of yellow passion fruit seedlings.
