The presence of plant-parasitic nematodes causing crop loss every year had been overlooked in the existing fruits, vegetables and flowers cultivation system Bangladesh. Therefore, study was conducted to isolate identify plantparasitic from soil infected plant-parts fruits (banana, orange), (pointed gourd, tomato brinjal) flower (gerbera) districts Jashore, Jhenaidah, Gazipur Sylhet during 2017-...

many powdery mildew fungi occur as anamorphic state on different host plants in guilan province, iran. the species have usually been identified as oidium spp. in order to identify teleomorphic species using anamorphic characteristics and host range, several infected plant specimens were collected from around guilan province during 2004-2011. based upon  the  results of the study 25 species were...

Longevity of cut flowers of many gerbera cultivars (Gerbera jamesonii) is typically short because of stem bending; hence, stem bending that occurs during the early vase life period is a major problem in gerbera. Here, we investigated the effects of sodium nitroprusside (SNP) on the delay of stem bending in the gerbera cultivars, Alliance, Rosalin, and Bintang, by examining relative fresh weight...

Development of composite inflorescences in the plant family Asteraceae has features that cannot be studied in the traditional model plants for flower development. In Gerbera hybrida, inflorescences are composed of morphologically different types of flowers tightly packed into a flower head (capitulum). Individual floral organs such as pappus bristles (sepals) are developmentally specialized, st...

Gerbera (Gerbera jamesonii Bolus and Hook,) is an ornamental Asteraceae of great commercial value, and pests can affect adversely its cultivation. More than 20 species of arthropods cause economic damage on gerbera, among them the two spotted mite, Tetranychus urticae Koch, 1836 (Acari: Tetranychidae), considered a key pest for this and other ornamental plants. In this work, some life-cycle asp...

به منظور مطالعه تاکسونومی جنس آنامورفیک oidium در استان گیلان نمونه های مختلفی از نقاط مختلف این استان جمع آوری و به آزمایشگاه قارچ شناسی گروه گیاه پزشکی دانشکده کشاورزی دانشگاه گیلان منتقل شد. پس از تهیه اسلاید های میکروسکوپی، مشخصات ریخت شناسی مربوط به مرحله غیر جنسی نمونه ها توسط میکروسکوپ نوری بررسی شدند. برای تعیین ابعاد اندام های قارچی، 30 مورد از هر کدام آن ها در چند نمونه میکروسکوپی، تو...

As a genetically determined structure, flower is an attractive object for developmental studies in plants. Flower development provides a good system for understanding cell differentiation and genetic mechanisms needed for organogenesis. The current molecular view on flower development has been based on studies on relatively few model species, like Arabidopsis and Antirrhinum. Research in model ...

Leibnitzia comprises six species of perennial herbs that are adapted to high elevation conditions and is one of only two Asteraceae genera known to have an exclusively disjunct distribution spanning central to eastern Asia and North America. Molecular phylogenetic analysis of Leibnitzia and other Gerbera -complex members indicates that Leibnitzia is monophyletic, which is in contrast with our e...
