“…Morphological characteristics of Lonicera pollen: sampling and fixation, dehydration and replacement, drying and coating, measurement and photography via scanning electron microscope were carried out as previously described (Xu and Yang 2007; Al-Hakimi et al 2018). On a sunny morning on 20–30 May 2020, 30 mature anthers (without cracks) from the flowers about to open in Lonicera were collected.…”

Due to extensive introduction and breeding, the taxonomic relationships of Lonicera L. are unclear. Alternative scientific methods are needed to explore the classification of these new Lonicera. In this paper, the pollen morphology characteristics, karyotype features, and floral and fruit pigment components of 13 taxa of Lonicera were analyzed by means of scanning electron microscopy, karyotype analysis, High Performance Liquid Chromatography Mass Spectrometry (HPLC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS). The 13 representatives of Lonicera were divided into groups of four, three, three and three taxa through the analysis of pollen morphology characteristics, karyotype features, floral composition and fruit pigment composition, respectively. Lonicera ruprechtiana and Lonicera tatarica always clustered together. Five hybrids, including Lonicera korolkow × Lonicera maackii and Lonicera korolkow × Lonicera tatarica No. 8 can generally be clustered with their parents. These results indicate that the analysis of pollen morphology characteristics, karyotype features, and floral and fruit pigment composition has value and significance for the study of systematic classification and relationships, and the conclusions of this study partially support morphological taxonomy.

In this paper, the pollen morphology characteristics, chromosome karyotype characteristics, floral and fruity pigment compositions of 13 species and hybrids of Lonicera L. were analyzed by means of scanning electron microscopy, root tip squash method, HPLC-MS and GC-MS, and then they were classified separately to discuss their genetic relationship and taxonomic relationship. According to the morphological taxonomy, Lonicera L. distributed in northern are divided into two categories by whether the branchlets are hollow or not. In this experiment, Lonicera chrysanthaTurcz. ex Ledeb., Lonicera maackii (Rupr.) Maxim., Lonicera ruprechtiana Regel., Lonicera tatarica Linn. and Lonicera korolkowi ‘Zabelii’. belongsto the category of hollow branchlets; and Lonicera edulisTurcz. and Lonicera tatarinowiiMaxim. belongs to the category of branchlets with solid white pith. Through the analysis of pollen morphology characteristics, chromosome karyotype characteristics, floral and fruit pigment compositions, and using the above four indexes for clustering, Lonicera ruprechtiana Regel. and Lonicera tatarica Linn. can always be clustered together. Five hybrids such as Lonicera korolkow‘Zabelii’.×Lonicera maackii (Rupr.) Maxim., Lonicera korolkow‘Zabelii’.×Lonicera tatarica Linn.No.8 etal. can basically clustered with their parents, which is conform to the morphological taxonomy. These results indicate that the analysis of pollen morphology characteristics, chromosome karyotype characteristics, floral and fruit pigment compositions, has certain value and significance for the study of system classification and genetic relationship of Lonicera L., and the conclusions of this study partially support morphological taxonomy. Among the four clusters, the clustering result of pollen morphology characteristics was in the highest agreement with morphological taxonomy.

“…They can be used to solve the taxonomic problems of plant groups, such as identification, taxa delimitation, classification and relationship assessment (Yao and Zhang 2016;Al-Hakimi et al 2017;Tripathi et al 2017;Ruiz-Domínguez et al 2019;Chen et al 2019;de Souza et al 2019;Ragho 2020). The pollen morphological characters such as polar axis length (P), equatorial diameter (E), P/E ratio, pollen sculpture or exine ornamentation (Via do Pico and Dematteis 2013;Ferrauto and Pavone 2014;Sarwar et al 2015;Al-Hakimi et al 2018), pollen size, pollen shape, exine thickness (Akhila and Beevy 2015;Krachai and Pornpongrungrueng 2015;Noedoost et al 2021) are valuable for distinguishing and identification of many plant groups.…”

Abstract. Suratman, Suranto, Muzzazinah, Purnomo. 2022. Pollen morphological characters variation among species of Strobilanthes s.l. from Sumatra, Indonesia and its taxonomic implications. Biodiversitas 23: 4636-4648. The objective of this study was to evaluate pollen morphological characters variation and its taxonomic value among species of Strobilanthes s.l. from Sumatra. A total of 32 species from four genera previously recognized within the subtribe Strobilanthineae were used for pollen morphology observations using Light Microscope (LM) and Scanning Electron Microscope (SEM). A total of ten pollen morphological characters (both quantitative and qualitative) were observed in this study. In general, a great variation occurs in the majority of investigated pollen morphological characters. A similarity dendrogram among species of Strobilanthes s.l. based on pollen morphological character data revealed two major clusters. Cluster I consist of 25 species that differed from species in Cluster II in having pollen type I, pollen type II and pollen type III with a similarity coefficient of 0.61. Cluster II consists of seven species and has pollen type IV, pollen type V, pollen type VI and pollen type VII with a similarity coefficient of 0.46. An identification key to the species of Strobilanthes s.l. based on pollen morphology is also established for easy discrimination of the investigated taxa. This study revealed that pollen morphology was taxonomically useful character for identification and taxa delimitation of Strobilanthes s.l., especially at the species level. The results of this study also support earlier works through molecular studies, statistical analysis, gross morphology observations and leaf anatomy studies that all segregate genera of the subtribe Strobilanthinae should be merged under a single and well-defined genus as Strobilanthes s.l.
