Induksi Poliploid Pada Kultur Antera Lilium longiflorum Thunb.

Biofaal Journal
Poliploidisasi memiliki peranan penting dalam upaya pemuliaan beberapa tanaman hias, seperti pada bunga lili (Lilium sp.), dengan tujuan untuk menghasilkan bunga yang berukuran lebih besar dengan tangkai perbungaan yang lebih kokoh. Poliploid dapat diinduksi dengan senyawa colchicine pada waktu perendaman tertentu.

Temperature‐dependent pollinator‐mediated selection on floral thermoregulation

New Phytologist, Volume 249, Issue 4, Page 1716-1726, February 2026.
Summary The thermal environment is one of the most pervasive agents of selection. Most plants cannot choose their microclimate, so understanding how they cope with thermal variability is of critical concern. Several floral traits can modify the floral thermal microenvironment, which may alleviate negative impacts of thermal extremes on gametophytes and

Comparative Evaluation of Topical Stabilized Retinaldehyde 0.1% vs. 0.05% on Skin Biophysical and Biomechanical Parameters

Skin Research and Technology, Volume 32, Issue 2, February 2026.
ABSTRACT Background The aim of this study was to evaluate the biophysical and biomechanical effects of topical stabilized retinaldehyde (RAL) treatments on skin, using different concentrations of retinal (0.05% and 0.1%). Materials and Methods Employing a split‐face design and noninvasive methods such as high‐frequency ultrasonography, the Antera 3D ...

Una nueva especie de Miconia (Melastomataceae) con anteras connadas de Colombia

Revista de la Academia Colombiana de Ciencias Exactas, Físicas y Naturales, 2019
The Miconieae tribe comprises about 1,900 Neotropical species and recent studies propose only one genus for the tribe, Miconia, which includes all of the genera previously considered including Tococa. Here we describe and illustrate a new species of the genus Miconia with lateral connate anthers from the department of Chocó, Colombia. This new taxon is

Floral shape and color impact heat accumulation and thermal stability of the floral microenvironment in a subalpine meadow

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise The floral thermal microenvironment impacts plant reproduction through its effects on gametophyte performance and plant–pollinator interactions. Color and shape are axes of floral variation that may mediate floral temperature because they affect the absorption and reflection of solar radiation, but their interactive effects are unclear.
