Introduction – Poor fruitfulness of subtropical table grapevines can reflect a low carbohydrate (CHO) status of the plant during floral bud formation and fruit development. CHO reserves can ameliorate poor fruitfulness. Such supplementation can be achieved by sucrose injection into the grapevine trunk; however, poor hydraulic conductance of stem tissues limits the success of this procedure. The objective of this study was to evaluate the co-addition of KCl to the sucrose solution to improve the hydraulic conductivity of grapevine shoots. Materials and methods – The hydraulic conductance of 15 cm long current season cane cuttings was assessed under a pressure gradient of 7.84 kPa during perfusion with water, KCl (1 to 50 mM) and sucrose solutions (2.5%, 5% and 7.5% w/v) in 0 and 10 mM KCl. Experiments were conducted over both short (about 2 hours) and long (about 78 hours) term. Additionally, transpiration of dye solutions enabled estimation of direct xylem conduits was undertaken. Results and discussion – Hydraulic conductance increased by about 20% with perfusion of ≥10 mM KCl compared to water, with the effect reversible and repeatable. Sucrose solutions caused a decrease in conductance relative to water. Co-addition of KCl mitigated the sucrose-mediated decrease in conductance. There was no evidence of physical vessel blockage such as tyloses or microbiota. Conclusion – The results are consistent with the hypothesis that cations cause shrinkage of pectins, increasing the conductance of pit membranes.
简介-亚热带台式葡萄的低果性反映了植物在花蕾形成和果实发育过程中的低碳水化合物（CHO）状态。CHO储备可以改善不良果性。这种补充可以通过将蔗糖注射到葡萄树干中来实现；然而，干组织的水力传导能力差限制了该手术的成功。本研究的目的是评估在蔗糖溶液中共同添加KCl以提高葡萄枝条的导水性。材料和方法-在7.84 kPa的压力梯度下，用0和10 mM KCl中的水、KCl（1至50 mM）和蔗糖溶液（2.5%、5%和7.5%w/v）灌注时，评估了15 cm长的当前季节甘蔗插条的水力传导率。实验在短期（约2小时）和长期（约78小时）内进行。此外，染料溶液的蒸腾作用使直接木质部导管的估计得以进行。结果和讨论-与水相比，灌注≥10 mM KCl时，水力传导率增加了约20%，其效果是可逆和可重复的。蔗糖溶液导致电导率相对于水降低。KCl的共同加入减轻了蔗糖介导的电导降低。没有证据表明存在物理性血管堵塞，如泰洛菌或微生物群。结论-该结果与阳离子导致果胶酶收缩、增加凹坑膜电导的假设一致。
