Nordic Journal of Botany, Volume 2026, Issue 6, June 2026.Penstemon digitalis is an early spring‐flowering species of the northwest Missouri prairie community, a period often characterized by low and unpredictable bee visitation. We conducted an experimental field study to evaluate how pollinator‐mediated pollen transfer and floral longevity interact to influence pollen acquisition and seed production.

Sporogenesis and development of gametophytes in an endangered plant, Tetracentron sinense Oliv
Biological Research, 2012 The sporogenesis and development of gametophytes in Tetracentron sinense Oliv. were studied with light microscopy. The anther has four microsporangia; its primary anther wall consists of an epidermis, an endothecium, one or two middle layers and one ...

A New and Minuscule Annual Species of Montia (Montiaceae) From Alpine Fens in Otago, New Zealand
New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.Montia minuscula Heenan is recognised as a new species from alpine habitats in Otago, South Island, New Zealand. It is currently known from only two locations, one in the Old Man Range (Kopuwai Conservation Area) and another in The Remarkables. It grows in palustrine fens that are associated with groundwater seepage such as from snowmelt and snowbanks.

Is Self‐Pollination Sufficient to Maximise Seed Set and Fruit Quality in Kiwifruit Hermaphrodites?
New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 2, June 2026.The purpose of this study was to determine whether supplementary pollination of each of two hermaphrodite kiwifruit selections was likely to produce any significant improvement in seed set or fruit quality, compared with self‐pollination alone. Three main pollination treatments were applied to floral shoots: self‐pollination alone and self‐pollination ...

Molecular phylogenetics clarifies generic boundaries of the papilionoid legume subtribe Clitoriinae
TAXON, Volume 75, Issue 3, June 2026.Abstract Clitoriinae is a morphologically distinctive and pantropically distributed subtribe within the legume tribe Phaseoleae (Leguminosae, Papilionoideae), yet its genus‐level taxonomic classification remains uncertain. This study presents the most comprehensive phylogenetic analysis of Clitoriinae to date, integrating plastid (matK/trnK) and ...

Studies on Sterility in Barley. : V. Determination of the Dehiscing Power of Anther
Japanese Journal of Crop Science, 1954 It has previously been shown by the writer that the wea.kness of dehiscing power of anther is the most critical factor governing the incidence of sterility in barley. Since this power has been hitherto judged n]ainly from the observation of a few characters, that is, degree of opening of anther, velocity of dehiscence and so on, measurement based upon ...

New Phytologist, Volume 250, Issue 6, Page 3747-3768, June 2026.Summary Stone cells originate from secondary cell wall thickening and contain abundant lignin. Their excessive accumulation compromises pear fruit quality, yet the endogenous hormonal mechanisms governing stone cell formation remain unclear. Here, co‐expression network analysis using transcriptome data – the flesh of 206 sand pear accessions sampled at
