Overcoming the limitations to yield in strawberry

在阅读大学进行的先前研究中，建立了一种生产高产六月草莓托盘植物的技术;与标准商业条件下生产的那些相比，这些植物产生了显着更高的产量。继续调查表明，由于果实发育过程中的来源限制，进一步的产量效益受到限制。该博士项目旨在研究一些提高这些超级精英植物产量表现的机制，包括通过CO2富集提高光合效率，调整饲料制度和在结果期间对植物进行操作（即改变叶面积指数，果实：叶比）并研究这些对资源分配，浆果重量，产量和果实质量的影响。该项目的第二个目的是研究英国和海外育种计划最近开发的高产草莓品系的产量决定因素。这项研究将打破目前草莓的产量上限，从而提高单位面积的生产率，从而使该行业受益。该学生将在阅读大学工作，并与阅读大学园艺中心的软果技术小组以及NIAB EMR的作物科学和生产系统系的其他人一起工作。培训将使学生发展强大的园艺技能，统计技术，并显着发展植物生理学和生长分析的知识。

In previous studies carried out at the University of Reading, a technique to produce high-yielding June-bearer strawberry tray plants was established; these plants produced a significantly higher yield compared to those produced under standard commercial conditions. Continued investigation showed that further yield benefits was limited because of source limitation during fruit development. This PhD projects aims to investigate a number of mechanisms to increase yield performance in these super-elite plants including increasing photosynthetic efficiency through CO2 enrichment, adjusted feed regimes and manipulation of the plants during fruiting (i.e. changing leaf area index, fruit:leaf ratio) and study the effect of these on resource partitioning, berry weight, yield and fruit quality. A secondary aim of this project will be to examine the yield determinants of recently developed, high yielding strawberry lines from UK and overseas breeding programmes. This research will benefit the industry by breaking the current yield ceiling in strawberry leading to increased productivity per unit area. The student will be based at the University of Reading and work alongside others within the Soft Fruit Technology Group at the Centre for Horticulture, University of Reading and the Crop Science and Production Systems Department at NIAB EMR. Training will enable the student to develop strong horticultural skills, statistical techniques and significantly develop their knowledge of plant physiology and growth analysis.
