| 2 | X-ray imaging of 30 year old wine grape wood reveals cumulative impacts of rootstocks on scion secondary growth and Ravaz index显示文摘Annual rings from 30 year old vines in a California rootstock trial were measured to determine the effects of 15 different rootstocks on Chardonnay and Cabernet Sauvignon scions.Viticultural traits measuring vegetative growth,yield,berry quality,and nutrient uptake were collected at the beginning(1995 to 1999)and end(2017 to 2020)of the lifetime of a vineyard initially planted in 1991 and removed in 2021.X-ray Computed Tomography(CT)was used to measure ring widths in 103 vines.Ring width was modeled as a function of ring number using a negative exponential model.Early and late wood ring widths,cambium width,and scion trunk radius were correlated with 27 traits.Modeling of annual ring width shows that scions alter the width of the first rings but that rootstocks alter the decay of later rings,consistently shortening ring width throughout the lifetime of the vine.Ravaz index,juice pH,photosynthetic assimilation and transpiration rates,and instantaneous water use efficiency are correlated with scion trunk radius.Ultimately,our research indicates that rootstocks modulate secondary growth over years,altering physiology and agronomic traits.Rootstocks act in similar but distinct ways from climate to modulate ring width,which borrowing techniques from dendrochronology,can be used to monitor both genetic and environmental effects in woody perennial crop species. | ZoëMigicovsky Michelle Y.Quigley Joey Mullins Tahira Ali Joel F.Swift Anita Rose Agasaveeran Joseph D.Dougherty Brendan Michael Grant Ilayda Korkmaz Maneesh Reddy Malpeddi Emily L.McNichol Andrew W.Sharp Jackie L.Harris Danielle R.Hopkins Lindsay M.Jordan Misha T.Kwasniewski R.Keith Striegler Asia L.Dowtin Stephanie Stotts Peter Cousins Daniel H.Chitwood | 2023 | Horticulture Research2023，10，1： | 1 |

| 5 | 喂料后称重肉种母鸡显示文摘在美国,大多数家禽生产商采取隔日饲喂方案来控制种用小母鸡体重。在当前鸡舍条件下,隔日饲喂方案是给所有鸡均匀分配饲料最好的方法,以保证鸡群均匀度。但是,嗉囊或者消化道内有食物会使鸡只的实际体重增加而且随着时间延长消化道内饲料逐渐减少。因此,后备种鸡一般在未采食的那天进行称重以规范数据,将体重与嗉囊或者消化道内有无饲料分开。然后每周在固定时间称重。这样称得的体重称为“空腹”体重。 | R.Keith Bramwel Jon R.Moyle Doug E.Yoho Bob S.Harper | 2008 | 中国家禽2008，30，23： | 0 |
| 6 | 创建优秀孵化场的秘诀显示文摘优秀的孵化场离不开两个主要领域,即输入品——种蛋的质量以及孵化场自身设备条件和管理。本文从这两个领域着手,探讨建设优秀孵化场应注意的环节。 | 韩浩月(译) 潘雪男(审) 韩浩月(制图) R.Keith Bramwell | 2021 | 国外畜牧学(猪与禽)2021，41，4： | 0 |
