摘要:

【目的】 评估大豆品种产量源、流、库指标对产量的贡献程度,明确产量形成过程中源、流、库各指标之间的相互关系,揭示影响大豆产量形成的关键生理机制,为大豆育种提供理论依据。【方法】 以大豆结荚期和鼓粒期为关键时期,采用13C同位素标记技术,系统分析齐黄34、临豆9号、潍豆9号、菏豆12在多生育时期的光合特性、器官物质积累及干物重变化,从源、流、库三方面对品种间生理特征进行综合评价。通过雷达图对各类指标进行整合分析,旨在阐明不同大豆品种产量形成过程中源、流、库关系的差异及其协同特征。【结果】 (1)源、流、库各指标与产量的相关性不同,与大豆产量的相关性强弱依次为:叶面积指数>百粒重>净光合速率>栅栏组织厚度>实际光化学效率>谷氨酰胺合成酶活性>谷氨酸合成酶活性>筛管平均直径>气孔导度>主叶脉直径。(2)源、流、库各指标存在互作。源库互作表现为:净光合速率、气孔导度、蒸腾速率与百粒重呈正相关关系;源流互作表现为:栅栏组织厚度与净光合速率、叶片厚度与净光合速率呈正相关关系;库流互作表现为:百粒重与筛管平均直径呈正相关关系。(3)不同大豆品种间源、流、库的表现有差异,齐黄34的叶面积指数、栅栏组织厚度、叶片厚度、净光合速率、实际光化学效率、主茎荚的持续积累能力、产量、百粒重、谷氨酰胺合成酶活性、谷氨酸合成酶活性、3 d主茎荚的转运能力、主茎荚的持续转运能力均高于其他3个品种。菏豆12的主叶脉直径、潍豆9号的株粒数、临豆9号的分枝荚碳吸收能力则高于其他3个品种,表明大豆高产的形成不依赖于单一的指标,而是源、流、库3个系统性指标的协同作用。【结论】 在4个供试品种中,齐黄34产量显著高于其他品种,主要优势在于较高的叶面积指数、较强的物质转运能力及较大的百粒重。在大豆育种中,为选育源、流、库协调的大豆高产品种,应基于实际光化学效率、净光合速率和叶面积指数等指标筛选高光效种质资源,再结合叶片与维管束解剖结构评价同化物运输效率,最后综合氮代谢酶活性及库容性状判断产量潜力,实现高产大豆品种的高效选育。

Abstract:

【Objective】 To evaluate the contributions of source, flow and sink traits to soybean yield, clarify the relationships among these traits during yield formation, reveal the key physiological mechanisms underlying soybean yield formation, and provide a theoretical basis for soybean breeding. 【Method】 Qihuang 34, Lindou 9, Weidou 9, and Hedou 12 were investigated during the pod-setting and seed-filling stages. The photosynthetic performance, assimilate partitioning, and dry matter accumulation were analyzed throughout plant development by using 13C isotope labeling. Source-flow-sink traits were comprehensively evaluated, and radar chart analysis was applied to characterize the coordination of these traits among cultivars during yield formation.【Result】 (1) The correlations between source, flow and sink traits and yield varied considerably. The contributions of these traits to yield ranked as follows: leaf area index > 100-seed weight > net photosynthetic rate > palisade tissue thickness > effective quantum yield of PSII (ΦPSII) > glutamine synthetase activity > glutamate synthase activity > mean sieve tube diameter > stomatal conductance > midrib diameter. (2) Significant interactions were observed among source, flow and sink traits. Source-sink interactions were reflected by positive correlations of net photosynthetic rate, stomatal conductance and transpiration rate with 100-seed weight. Source-flow interactions were indicated by positive correlations of palisade tissue thickness and leaf thickness with net photosynthetic rate, whereas flow-sink interactions were represented by a positive correlation between mean sieve tube diameter and 100-seed weight. (3) Source, flow and sink traits differed markedly among cultivars. Qihuang 34 exhibited higher leaf area index, palisade tissue thickness, leaf thickness, net photosynthetic rate, ΦPSII, sustained dry matter accumulation in main stem pods, yield, 100-seed weight, glutamine synthetase activity, glutamate synthase activity, 3-day assimilate translocation to main stem pods and sustained assimilate translocation than the other three cultivars. Hedou 12 showed the largest midrib diameter, Weidou 9 had the highest seed number per plant, and Lindou 9 exhibited the greatest carbon assimilation capacity of branch pods. These results indicate that high soybean yield depends on the coordinated regulation of source, flow and sink traits rather than on any single trait.【Conclusion】 Among the four cultivars, Qihuang 34 achieved the highest yield owing to its larger leaf area index, stronger assimilate transport capacity, and greater 100-seed weight. Breeding high-yield soybean cultivars with coordinated source, flow and sink characteristics should prioritize germplasm with high photosynthetic efficiency based on ΦPSII, net photosynthetic rate and leaf area index, followed by evaluation of assimilate transport efficiency using leaf and vascular bundle anatomical traits and assessment of yield potential through nitrogen metabolism enzyme activities and sink capacity.
