“…Lamium amplexicaule L. possesses a heteroblastic inflorescence in which two breeding systems coexist. These two breeding systems are the cleistogamous system that contains closed, autogamous or self-pollinated flowers (CL) and the chasmogamous system with opened, allogamous or xenogamous pollinated or cross-pollinated flowers (CH), as reported earlier (Lord, 1979(Lord, , 1982Sato et al, 2013;Azimishad et al, 2018Azimishad et al, , 2019Stojanova et al, 2020). Both the CL and CH flowers have been observed in the same individual in earlier studies (Lord, 1979;Sato et al, 2013;Woolam, 2016).…”

I N EGYPT, the genus Lamium L. (Family Lamiaceae) is represented by L. amplexicaule L., which possesses a heteroblastic inflorescence in which two breeding systems coexist. These two breeding systems are the cleistogamous system that processes self-pollinated, closed flower (CL) and the chasmogamous system with cross-pollinated, opened flower (CH). Although the pollen grains of the family Lamiaceae and Lamium spp. have been extensively investigated, the palynomorphological data distinguishing the pollen features for the CL and CH flowers are still lacking. This study aimed to (1) add more information about the palynomorphology of CL and CH flowers; (2) investigate the similarities and differences in palynomorphology between the pollen of these two flower types; in the same and different L. amplexicaule morphs. Our results showed that the heteroblastic inflorescence in L. amplexicaule L. in Egypt was represented by five pollen grain types. The scanning electron microscopy (SEM) results showed that all the pollen grain types were monads, tri-zonocolpate, isopolar, radially-symmetrical and reticulate, or microreticulate sculpture. The colpus length/colpus width ratios, P/E, apocolpium, and mesocolpium widths in the studied heteroblastic inflorescence were significantly different in the CL and CH flowers in the same and different morphs. The present study developed a key differentiating the five pollen grain types. In conclusion, this study confirms that the pollen characteristics were significantly different between and among the CL and CH flowers that coexist in the heteroblastic inflorescences of L. amplexicaule; this feature requires future clarification in different taxa.

Nowadays, the flower industry is growing so fast that its development requires introducing new varieties to the flower market. Iran is the habitat of numerous species of wild plants that are among the valuable genetics in the breeding process. The identification of native Iris species, investigation of morphological diversity, and distribution method have a significant effect on the introduction of this flower as new and superior cultivars cut flower and bedding plant. The documentation of the most important habitats of Iris in Arak province, identification of morphological characteristics and correlation determination of morphological traits are the most important aims of this research. The results showed that there is a correlation between some of the traits. The highest positive correlation was related to the height of flower and length of the leaf, length of the flowering stem and the length of the leaf and the height of the flower and the length of the flowering stem. The ecotypes of Iris sp. were divided into six groups. Based on the results of the cluster diagram, the bulbous species were separated from rhizome species. Generally, due to the color diversity of Iris sp. and unique beauty of the flowers and the resistance of the native species, they can be used as native foundations. Due to the prominent traits such as high durability of Iris meda, odor of I. hymernospatha Subsp. leptoneura and color diversity of I. persica, I. songarica and height of I. spuria, they can be used to introduce new ornamental species. Iris spuria is the most suitable genotype because of the high height, large flower, high durability, and beautiful flower.

Lamium amplexicaule L. (Family: Lamiaceae) is a cosmopolitan weed whose eradication is challenging. The phenoplasticity of this species is related to its heteroblastic inflorescence, which has not received adequate research worldwide in its morphological and genetic aspects. This inflorescence hosts two flower types, a cleistogamous (CL: closed flower) and a chasmogamous (CH: opened flower). This species subjected to detailed investigation is a model species to clarify: (1) the existence of the CL and CH flowers in relation to the time and individual plants. (2) the predominant flower morphs in Egypt. (3) the morphological and genetic variability between these morphs. Among the novel data retrieved from this work is the Presence of this species in three distinct morphs coexisting during winter. These morphs showed remarkable phenoplasticity, particularly in flower organs. Significant differences were observed between the three morphs in pollen fertility, nutlets productivity and sculpture, flowering time, and seed viability. These differences were extended to the genetic profile of these three morphs assessed by the inter simple sequence repeats (ISSRs) and start codon targeted (SCoT). This work highlights the urgent need to study the heteroblastic inflorescence of crop weeds to facilitate its eradication.
