Micropropagating American chestnut plantlets in the Plant Tissue Culture Lab at @SUNY ESF 🔪🌱 More information: These clonally propgated chestnuts are not meant for restoration or field plantings. We use tissue culture trees for research purposes only such as studying OxO gene expression or conducting controlled fungal inoculations. We also put tissue culture generated trees into high light growth chambers to produce transgneic pollen to be used in controlled pollinations! #americanchestnut #bi

There are a few putative survivor American Chestnut trees growing in Philadelphia, but they’ve never been tested. I’m sending in a sample of two nearby trees to the PA/NJ chapter of the American Chestnut Foundation! In ~2 months, we should know more about the tree and if it’s actually a resistant American chestnut, or a hybrid of some sort. I’ll keep you all updated! #trees #americanchestnut #castaneadentata #chestnut #tree #arborist #urbanforestry #philadelphia #philly #chestnutblight | Andrew

Chestnuts were a staple for wildlife, and their rot-resistant wood was highly valued for building and furniture making. However, in the early 20th cen
