Physiological and analytical data in response to treatments with different nitrogen forms and iron deficiency in hydroponic with grapevine rootstocks

Iron (Fe) chlorosis is a severe problem in viticulture resulting in impaired plant development, yield loss and reduced fruit quality. Nitrogen forms (nitrate and ammonium) can play a role in promoting or mitigating Fe ddeficiency stresses. The study investigated the response of two grapevine rootstock genotypes (Fercal (Vitis. berlandieri x V. vinifera) and Couderc 3309 (V. riparia x V. rupestris)) to both N-forms in combingation with Fe deficiency. Photosynthesis of the plants were measured as well as key metabolites associated to iron mobilization were analyzed. Presented raw data have been summarized in a submitted manuscript to BMC Plant Biology.

铁（Fe）失绿症是葡萄栽培领域的一类严重问题，会导致植株生长发育受阻、产量损失及果实品质下降。氮素形态（硝酸盐（nitrate）与铵盐（ammonium））可在铁缺胁迫的发生发展中发挥加剧或缓解作用。本研究针对两种葡萄砧木基因型——Fercal（Vitis berlandieri × Vitis vinifera）与Couderc 3309（Vitis riparia × Vitis rupestris）——展开实验，探究其在两种氮素形态结合铁缺胁迫下的响应。实验测定了植株的光合参数，并分析了与铁动员（iron mobilization）相关的关键代谢物。本数据集附带的原始数据已整理至已投稿至《BMC Plant Biology》的研究手稿中。
