Postharvest bacterial succession on cut flowers and vase water.
In cut flowers, xylem occlusion or blockage by bacteria negatively affects water balance and postharvest quality. Many studies have used culture-based methods to examine bacterial populations in vase water and their effects on flower longevity.

This study aimed to investigate the effects of individual and combined applications of agricultural biogas slurry (ABS) and a plant protection preparation (GZM) on enhancing the yield of silage maize. In four different 15 ha fields of green silage maize, the treatments of control, ABS, GZM, and a combination of ABS and GZM were applied in sequence ...

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Costa Rica
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Costa Rica.

The hidden diversity of vascular patterns in flower heads
Summary Vascular systems are intimately related to the shape and spatial arrangement of the plant organs they support. We investigate the largely unexplored association between spiral phyllotaxis and the vascular system in Asteraceae flower heads. We imaged heads of eight species using synchrotron‐based X‐ray micro‐computed tomography and applied ...

Summary Gorteria diffusa has elaborate petal spots that attract pollinators through sexual deception, but how G. diffusa controls spot development is largely unknown. Here, we investigate how pigmentation is regulated during spot formation. We determined the anthocyanin composition of G. diffusa petals and combined gene expression analysis with protein
