Evaluation of sunn hemp performance and nutritive value in Maine, USA

Grassland Research, EarlyView.
Abstract Background Sunn hemp (Crotalaria juncea L. and Crotalaria ochroleuca G. Don) was evaluated as a warm‐season legume to mitigate the “summer slump” in Maine's forage production caused by heat and moisture deficit stress. Methods This study compared three cultivars: “Crescent Sunn,” “Loei,” and “Red Mini,” at 60 and 90 days after seeding over the

Pollination biology of fruit-bearing hedgerow plants and the role of flower-visiting insects in fruit-set

, 2009
Background and Aims: In the UK, the flowers of fruit-bearing hedgerow plants provide a succession of pollen and nectar for flower-visiting insects for much of the year.

Floral phenology and standardization of hand pollination of Clove (Syzygium aromaticum (L.) Merr. & Perry)

Clove (Syzygium aromaticum (L.) Merr. & Perry) has a rich history and is highly valued for its culinary and medicinal uses. However, its limited genetic diversity and tendency for self-pollination pose challenges for optimizing its cultivation in ...

Late Quaternary climatic variability in the Eastern Mediterranean recorded in Hermes Cave, Corinth Rift, Greece

Journal of Quaternary Science, EarlyView.
ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

A new, ~4500‐year varve record and high‐resolution tephrochronology from lake Hämälänlampi, eastern Finland, provides age constraints for the Furnas C and the Glen Garry/Askja A‐2000 eruptions

Journal of Quaternary Science, EarlyView.
ABSTRACT The northern European distal cryptotephra framework is constantly developing both in terms of identification of new tephra horizons and improved age constraints for the already well‐established tephra marker horizons. However, many prehistoric tephra layers have only been dated by the radiocarbon method, with its inherent problems.

Factsheet no. 4 Simple Hand Pollination for Coconut Palms

This factsheet explains how farmers can use simple hand-pollination techniques to produce better-quality coconut seednuts. It describes why hand pollination is useful, how to isolate female flowers to control which palm provides pollen, and two practical methods: bagging individual flowers and bagging the whole inflorescence.
