“…For example, Malvaceae family has plants which possess spiny, circular, and large pollen types (Shaheen et al, 2010). Pollen morphology of some selected cultivated plant species at the University of Arid Agriculture, Rawalpindi, Pakistan were reported by Noor et al (2004) and they observed various shapes and fertility of the pollen which is helpful in studying the variation within plant species and delimitation of the taxa (Noor et al, 2004). Acacia nilotica pollens are polyads type and vary in shape from circular to ovoid with psilate sculpturing (Rajurkar et al, 2013).…”

“…It may also help in Melissopalynology which is used in honey (Aftab & Perveen, 2006). Pollen micromorphology may also useful in terms of forensic palynology, archeology, and tracing the history of vegetation, genetics, climate change studies, and study of past human impacts on vegetation (Noor et al, 2004). A wide range of variation in size and sculpture shows the potential taxonomic value.…”

“…Palynology is the study of pollen features in plants and applied to systematics, genetics, and forensic studies (Noor et al, 2004). The information obtained from pollen studies can be utilized as a tool for number of scientific researches in systematic botany, paleobotany, paleoecology, pollen analysis, aeropalynology, criminology, allergy, stratigraphic correlation of oil-bearing rocks and coal fields, drugs in the field of medicopalynology, and improvement of honey in the field of mellittopalynology and copropalynology (Meo, 2005).…”

The present study planned to assess the medicinally important plants in the lower Margalla Hills of Islamabad, Pakistan using scanning electron microscopy of their pollens. Both quantitative and qualitative characters of the pollens were analyzed. The shapes of the pollen were prolate, spheroidal, elliptical, and oblate. Exine sculpturing showed rugulate, scabrate, psilate gemmate, and reticulate ornamentation. The people residing in the rural areas are thought to depend, primarily, on medicinal plant resources for many health care needs. A sample of 140 respondents was selected and interviewed by using a stratified random sampling technique. Results showed that the local communities of lower Margalla Hills are highly dependent on plants to treat various ailments, for example, respiratory (28%), digestive (46%) nervous, circulatory and dermatological problems (6% each), and reproductive problems (8%). The continuous dependence of the local community on ethnomedicinally important plants has led to serious degradation of the natural forest of lower Margalla Hills. Priority-based conservation and sustainable use of these forest resources are necessary, and use of alternative resources will also help in the forest conservation.

“…In seed formation fertile pollen is very necessary. Studies of pollen fertility are very helpful for recognition of wide range of variations existing within plants species and differentiating plant species with genera (Noor et al, 2004). The main objective of this study is to determine chromosome number, karyotype analysis, meiotic behaviors and pollen fertility of the taxa Calendula officinalis L.…”

The present study includes chromosome number, karyomorphology, meiotic behaviors and pollen fertility of the species Calendula officinalis L.collected from central Nepal was cytologically carried out using two percent aceto-orcein for somatic chromosome determination and one percent aceto-carmine for meiotic study. Pollen fertility was based on stainability test using Muntzing solution. Somatic chromosome number determined for this taxon were 2n=28, haploid chromosome number n=14 and pollen fertility found to be 84.4 percent in the present study. In karyotype analysis chromosome length ranged from 0.4 to 2.6 µm and mean length was 1.5 µm. Likewise, absolute length found to be 21.9 µm and karyotype formula obtained was M16+m4+ sm8. Three types of chromosomes centromere at middle point, at median region and at sub –median region were observed. Meiosis with regular and irregular behaviors was observed in this study. The variations in chromosome numbers, irregularities in meiotic behaviors, variations in karyomorphological structure and high fertility rate shows evolve nature of this species which play a great role in evolution. Pollen fertility was also affected by meiotic abnormalities. Int. J. Appl. Sci. Biotechnol. Vol 9(1): 75-79

Background Rosa alba L. belongs to the family Rosaceae. This species is widely cultivated in Europe, Asia, North America, and Northwest Africa due to its fragrance, ornamental, and medicinal values. It is commonly known as white oil-bearing rose, white rose, white rose of York, backyard rose, and sufaid gulab. Main text Rosa alba L. has many biological properties like antioxidant, antimicrobial, antifungal, antifertility, teratogenic, memory enhancing, cytotoxic, and genotoxic activities. The essential oil of Rosa alba L. possesses good antimicrobial activity and consists of many chemical constituents like- citronellol, geraniol, nerol, linalool, citral, carvacrol, eugenol, etc. Conclusion This article briefly reviews the cultivation, traditional uses, phytochemistry, and biological activities of Rosa alba L. Many research papers have been published on the proposed plant and still, there is a very vast scope of research on it. Therefore, this review will be very fruitful for those scientists who are doing or plan to do research work on this plant. All the scientific findings written in this review are explored from Google web, Google Scholar, PubMed, ScienceDirect, Medicinal and Aromatic Plants Abstracts (MAPA), and SciFinder. To date, it is the first systematic review article of such kind, on this plant.
