Adventitious root formation is essential for the vegetative propagation of perennial woody plants. During the juvenile-to-adult phase change mediated by the microRNA156 (miR156), the adventitious rooting ability decreases dramatically in many species, including apple rootstocks. However, the mechanism underlying how miR156 affects adventitious root formation is unclear. In the present study, we...

By using shoot tips as explants, various media and culture conditions for callus induction and proliferation, shoot differentiation, root induction and plantlet transplantation to develop an efficient and reliable regeneration system with Dendrocalamus hamiltonii were tested. Murashige and Skoog (MS) medium supplemented with 3 mg/l 2, 4-dichlorophenoxyacetic acid, 1 mg/l benzyladenine (BA), 500...

An effi cient protocol for organogenesis through leaves has been established for Launaea sarmentosa (Willd.) Sch. Bip. ex Kuntze, a highly valuable medicinal plant. The leaf explants produced microshoots on MS basal medium when fortifi ed with cytokinins and auxins. A combination of 6-benzylaminopurine (BAP) at 0.5mg/l and naphthaleneacetic acid (NAA) at 0.2mg/l resulted in the induction of hig...

A field experiment was conducted using a 3 × 3 orthogonal regression design to explore the growth promotion of one-year-old Yunnan pine seedlings (Pinus yunnanensis Franch.) in response to foliar application of IAA (indole-3-acetic acid) at rates of 0, 200 and 400 mg·L(-1) and IBA (indole-3-butyric acid) at rates of 0, 200 and 400 mg·L(-1) in order to promote the growth during the seedlings' ea...

Background Picrorhiza kurroa (PK) belongs to Scrophulariaceae family and is a representative endemic, medicinal herb, widely distributed throughout the higher altitudes of alpine Himalayas from west to east, between 3000 and 4500 m above mean sea level. Objective The objective of the present study is to assess the production of picroside I and picroside II from tissue cultures of PK. Materi...

Pistacia lentiscus L. is a dioecious shrub or small tree with high drought resistance, native in the entire Mediterranean basin. The variety ‘Chia’ (mastic tree) cultivated for production of mastic gum (a resin produced after wounding trunks and thick branches) Island Chios (Greece), but it also has significant ornamental value. In present study, ten male female genotypes P. var. Chia from natu...
