Plant recognition is an important and challenging task. Leaf recognition plays an important role in plant recognition and its key issue lies in whether selected features are stable and have good ability to discriminate different kinds of leaves. From the view of plant leaf morphology (such as shape, dent, margin, vein and so on), domain–related visual features of plant leaf are analyzed and ext...
Reading involves the decoding of written forms into language forms that represent phonological, morphological, and word level units. Thus, orthographies convey not only phonological but also morphological information—the word roots, syntactic inflections, and derivational relations that constitute the minimal semantic and grammatical units of a language. There are many psycholinguistic issues b...
Bakhshi. M. 2019. A revision on the taxonomy of the genus Pseudocercospora. Plant Pathology Science 8(1):1-14. DOI: 10.2982/PPS.8.1.1. Pseudocercospora species are plant pathogenic fungi occurring on a wide range of herbaceous and woody plants. Since its early description of the genus, its taxonomy has always been challenging. In recent years, Multi-gene DNA sequence data have provided sig...
Grangea maderaspatana (L.) Poir. is a popular Indian medicinal plant belonging to the Asteraceae family. This plant commonly known as Madras Carpet grown in wet places. A wide range of phytochemical constituents have been isolated from this plant. It has long been used in traditional Ayurvedic Indian medicine for various diseases. This plant is pharmacologically studied for oestrogenicity, anti...
Although functional form and functional group models for marine algae have been used extensively, there is little general literature support for these models, and many studies have shown that associated hypotheses are often incorrect. In functional form/group models, a wide range of ecological and physiological functions are assumed to be correlated with general algal form or morphology. In con...

Theoretical models for allometric relationships between organismal form and function are typically tested by comparing a single predicted relationship with empirical data. Several prominent models, however, predict more than one allometric relationship, and comparisons among alternative models have not taken this into account. Here we evaluate several different scaling models of plant morpholog...
مورفولوژی دانه گرده جنس Rheum L. (Polygonaceae) در ایران با استفاده از میکروسکوپ نوری (LM) و میکروسکوپ الکترونی نگاره (SEM) مطالعه شد. دانههای گرده در نمای قطبی معمولا دارای تقارن محوری، در دو قطب مشابه، وسه شیاری اند در حالی که در نمای استوایی دایرهای شکلاند. تزیینات سطح اگزین متغیر است و به شکلهای با منافذ پراکنده تا منفذدار، میخچههای پراکنده (Rh. turkestanicum)، منافذ کشیده، میخچه دا...
