Abstract

Bauhinia scandens is an ornamental plant and it has anti-tumor properties. The demand for seedlings of this species makes it necessary to know about the germinative behavior of seeds and the initial growth of seedlings. The objective of the present work was to determine the type of substrate and moistening conditions that are more favorable to the emergence and development of seedlings of B. scandens. B. scandens seeds were disposed on three substrates: sand, vermiculite, and commercial substrate, maintained at four levels of moistening 25, 50, 75, and 100% of the water holding capacity of the substrate and kept in a greenhouse for 60 days. The following parameters were evaluated: emergence, speed index, average time, number of leaves, length of aerial part and root, diameter of neck, fresh and dry mass of aerial part and root. The analysis of variance was performed in a completely randomized design, in a 3 X 4 factorial scheme, with four replications of 25 seeds. The sowing of B. scandens should be carried out initially in vermiculite with a holding capacity of 100% until the establishment of the seedling emergence and then transplanted to commercial substrate keeping between 50 and 75% holding capacity.

Highlights

The objective of the present work was to determine the type of substrate and conditions for its moistening that are more favorable to the emergence and development of seedlings of B. scandens
B. scandens fruits were harvested from 10 parent plants in Botucatu-SP and sent to the Seed Analysis Laboratory of the Plant Production Department at UNESP, Jaboticabal, SP
The substrates were moistened with four levels of water holding capacity, these being 25, 50, 75 and 100%

Summary

Introduction

The plant gained prominence due to the medicinal properties of its leaves, from the isolation and identification of glycerol 1-O-alkyl, Hazra & Chatterjee (2008) established the antitumor property of this chemical compound through a bioassay, accepted internationally, called the Brine Shrimp toxicity test. For the domestication and rational exploitation of the economic potential of plants, it is necessary to develop techniques for the commercial production of seedlings (Jellani et al, 2016). The substrate is one of the most important external factors from germination to seedling development (Dutra et al, 2012). An ideal substrate has desirable chemical, physical, and biological characteristics for the growth of the root system, ensuring the supply of water, nutrients and root support during the entire period of seedling formation (Alves et al, 2017)
