Compared nymphal development of Tingis americana (Hemiptera, Tingidae) in two Handroanthus species (Bignoniaceae) and reproductive parameters in seedlings of Handroanthus heptaphyllus [PDF]
Iheringia - Serie Zoologia, 2013 Nymphs and adults of Tingis americana Drake, 1922 were found feeding on leaves of Handroanthus heptaphyllus (Vell.) Mattos and Handroanthus chrysotrichus (Mart. ex A. DC.) Mattos in the Botanic Garden, Porto Alegre, state of Rio Grande do Sul, Brazil. This is the first record of T. americana on these host plants and in the southern Brazil.

Seed Priming of Handroanthus heptaphyllus for the Restoration of the Mining Fields
Water, Air, & Soil Pollution, 2023Seed priming is a low-cost pre-sowing treatment used to improve germination and seedling establishment performance under adverse environmental conditions. The priming using signaling molecules, such as nitric oxide and hydrogen peroxide, act on plant growth and development alleviating the negative influence of abiotic stress by heavy metals. Thus, this

CRYOPRESERVATION AND OPTIMIZATION OF IN VITRO GERMINATION OF HANDROANTHUS SERRATIFOLIUS
Acta Horticulturae, 2015Handroanthus serratifolius is a tree species with wide distribution in Brazil which may be used as ornamental plant. It is propagated by seeds which loose viability within a short period. This study aimed to (i) test different thawing periods for cryopreserved seeds, (ii) evaluate the germination rate, fresh and dry weights of the seedlings, and (iii ...

In vitro organogenesis inHandroanthus serratifolius
Acta Horticulturae, 2017Handroanthus serratifolius, an ornamental Brazilian native tree, is traditionally propagated by seeds, that present a seasonal production and a fast lost of the viability. Thus, the in vitro organogenesis might be an alternative for propagation. The objective of this work was to optimize the different stages for the micropropagation process of this ...

A new combination in Handroanthus (Bignoniaceae) from Brazil
PhytotaxaWhile reviewing Vellozo’s Bignoniaceae names in Floræ Fluminensis, a nomenclatural novelty came to light. The name Bignonia longiflora Vellozo, being a later homonym of B. longiflora Cavanilles, was deemed illegitimate. Consequently, Vellozo’s name was eventually replaced with Tecoma speciosa Candolle ex Martius.
