Floral syndrome is one of the key components of plant pollination syndromes, affecting variety of evolutionary and ecological processes in angiosperms. The evolutionary transition from self-incompatible heterostyly to self-compatible homostyly occurred repeatedly in angiosperm families. Although the evolution of heterostyly and homostyly has been deeply studied, our understanding on their differences in ecological strategies is still lacking. In this work, using the floral syndrome and distributions of the primula in China we compared the spatial pattern of floral syndrome frequency and its climatic determinants. Our results reveal that distylous and homostylous primula have similar primary centers of species diversity in southwest China, while distylous species have larger range size than homostylous ones. Temperature seasonality is the dominant climate factor of these geographic patterns, but its effect is much stronger in distylous than in homostylous primula. Distylous species have larger flower size and number, and fruit size than homostylous ones. Climate, especially temperature seasonality mainly influenced species range size via its effects on floral syndrome. Our study suggests that homostyly is likely derived from heterostylous ancestors in similar geographical context, and larger reproductive investment in floral phenotype may provide compensatory mechanisms for obligate out-breeding heterostyly. Future investigations regarding the evolutionary history and tolerance or resistance to environmental change between distyly and homostyly may greatly advance our understanding of their spatial pattern and adaptative differences.

The circumscriptions of sections Auganthus Pax ex Balf. f. and Ranunculoides Chen et C. M. Hu in the genus primula L. have been controversial, due to the different treatments of P. filchnerae Knuth. We conducted a phylogenetic analysis using sequences from the ITS region of nuclear ribosomal DNA. All five species of these two sections and some representatives of other related sections were sampled. The ITS trees show that P. filchnerae could be convincingly placed in sect. Auganthus , together with P. sinensis Sabine ex Lindl. and P. rupestris Balf. f. et Farrer, whereas sect. Ranunculoides contains two species: P. cicutariifolia Pax and P. merrilliana Schltr. These two sections are distantly related and their association with other sections needs further studies. This study also demonstrated that ITS sequences would be a suitable marker for the reconstruction of primula phylogeny.

植物的花部性状在异质环境中表现出不均一的适应性进化,其自然变异可能在时空格局上呈现一定的规律性。选择同一物种的不同地理居群进行花部表型变异分析,能揭示花部性状随地理梯度的变异模式。海仙花报春(primula poissonii)属于典型的二型花柱植物,依赖昆虫传粉实现严格的型间异交。该物种广布于横断山地区亚高山–高山草甸,其分布海拔跨度大且花部性状在种内具有较高变异,但这些变异在不同地理梯度(海拔梯度和经纬度梯度)的特定选择因子作用下的变化规律尚不清楚。本研究选择海仙花报春16个居群,对8个花部关键性状和二型花柱繁殖器官的互补度与海拔和经纬度的关系进行研究,探究花部性状随地理梯度变异的模式及其潜在的选择因素。研究表明,海仙花报春两种花型的花冠管开口大小、花药高度以及短柱花柱头高度与海拔均呈正相关,但两种花型的花冠大小,长柱花的花瓣长度、柱头到花冠管开口的距离,以及短柱花的花冠管长度与海拔高度间均呈负相关,其余性状与海拔无显著相关性。除短柱花中柱头高度以外的性状均随着纬度升高而逐渐减小。长柱花中除花药和柱头间的距离以及柱头到开口的距离外,其余性状均随着经度的增加而减小;短柱花的花瓣长度、花药高度以及花药和柱头间的距离随着经度的增加而变大,其余性状均随着经度的增加而减小。繁殖器官间的互补度并不随地理环境的变化而变化。花部性状的地理变异可能受访花昆虫组成的地理变化驱动。繁殖器官间互补程度的高度保守表明非选型交配在居群二态性的维持和稳定过程中起关键作用。本研究为进一步深入开展报春花属(primula)花部性状及其选择压力的地理变异研究奠定了基础。

滇北球花报春(primula denticulata ***)的早春蓝紫色球状花序具有独特的观赏价值,但由于多种因素的影响,其天然群体正在逐渐减少。为评价其遗传多样性水平,我们对滇北球花报春10个天然群体进行了表型性状变异研究。结果表明:滇北球花报春8个表型性状在群体间和群体内均存在极显著差异,变异系数(CV)在4.73-9.90%之间,表型分化系数(Vst)在0.1541-0.4069之间,平均值为0.2854,群体内的变异是表型变异的主要来源。根据8个表型性状的UPGMA聚类分析将10个天然群体划分为3类。依本研究结果,在对滇北球花报春种质资源保护时进行就地保护是十分必要的,并且应该优先保护表型变异较为丰富的天然群体。

本文分别从物候、繁育结构和传粉等方面研究了国家三级保护植物、安徽特有种——安徽羽叶报春(primula merrilliana)的繁殖生物学特征。研究结果表明:(1)安徽羽叶报春是典型的形态和功能意义上的花柱二型的二年生植物,其始苗期为9月,一直持续到第二年6月底或7月初死亡,各居群长柱花植株比短柱花植株开花略早3-5d;(2)安徽羽叶报春的散孔型花粉显示其在报春花属中有重要的系统意义和进化意义。同时,短柱花花粉量比长柱花少,但其花粉直径是后者的1.78倍左右;(3)长花柱的雌蕊长度是短花柱的1.64倍,而且其柱头上的乳头状突起比短花柱上的长而稀;(4)3个研究居群的P/O比都不相同,我们发现花粉量比胚珠数量有更大的变异,这可能与生境有关;(5)安徽羽叶报春为异花授粉植物,蓟马属(Thrips)昆虫为其重要的传粉者,其同型花授粉可育性远比异型花授粉的高;(6)其长、短柱型种子没有明显的形态差异,多属不等边七面体,少为其他多面体。据研究,在小居群中两种花柱类型植株的比例失衡,生境的破坏和伴生种的消失可能是导致安徽羽叶报春濒危的重要原因。
