Ripening and harvest season just around the corner. Frontenac blanc, Frontenac gris, Frontenac noir, and Itasca. All multistate cold hardy adapted cultivars. Tracking Brix and TA across the season to see how hybrids ripen and manage elevated temperatures

❄️ 🍇 SPECIAL ISSUE RESEARCH ❄️ 🍇

Londo & Kovaleski's study demonstrates a link between cold hardiness and budbreak phenology, revealing a conserved and adaptive response to winter temperature in grapevine.

Fig. 6.Variation in winter physiology traits measured in this study sorted on cultivar type and deacclimation rate values. Deacclimation rates shown as the average maximum rate in °C d–1. Cold hardiness shown as average of maximum cold hardiness as determined by LT50 in °C. Chilling requirement as estimated with forcing assays (CHBB) and classification of chill shown as dynamic portions. Chilling requirement as determined with 50% Ψdeacc (CRDP) shown as dynamic portions. Temperature parameter for predicting budbreak using cold hardiness and deacclimation rates (CHBB).

It’s hard to believe we are already at veraison! Just a touch of color on the cold hardy hybrid cultivars. We are trying to see if all those winter hardiness traits make the vines more at risk to heat and drought.

Ah, nice. I hope it’s just the first one of the day.

It’s scary to be excited these days but I’m proud of our collaborative team and this new project to understand grafting and environmental variation effects on grapevine rootstock and scion epigenomics in vineyards across the Eastern US. @ajmiller4233.bsky.social

Uncovering ‘terroir’: Project to explore plant-environment interactions | Cornell Chronicle

A Cornell grape geneticist is leading a $2.3 million multi-institutional project to understand how genetically identical grapevines are influenced by varying environmental conditions in three states.

I thought this was the onion….

Increasing numbers of 🍎 trees seem to be declining in NY and I think we can detect it early. Maybe we can hyperspectrally “see” the physiological shift before canopy collapse. Behold the beauty of Apple tree decline.
