Root Regeneration in Transplanted Deciduous Nursery Stock

Renewal of Growth by Guayule Transplants.

Guayule seedlinos were received fromi the federal nursery of the Emergency Guayule Project at various times of the year for use in a general study of the growth of this species under greenhouse conditions (1). Stock removed from the nursery at different times of the year showed markedly different powers of regenerationi when transplanted to soil in the greenhouse. The best growth was obtained f...

Septoria Canker on Nursery Stock of Populus Deltoides

Septoria musiva Peck is capable of establishing itself on unwounded first-ye ar stems of eastern cottonwood. Natural infections have been observed since 1969 in three forest nurse ries in Mississippi, and inoculations have confirmed that both conidia and ascospores are capable of causing stem infections . This paper offers evide n ce that the fungus Septoria musiva Peck is capable of causing ca...

Applying the target plant concept to nursery stock quality

The basic tenet of the target plant concept is that the quality of nursery stock is determined by outplanting performance (survival and growth), rather than characteristics or standards measured at the nursery. This means that there is no all-purpose plant, but that each outplanting project will require different species and stock types. In this paper, we discuss the six basic questions that he...

Deciduous Mandibular Second Molar with Supernumerary Roots and Root Canals

An accurate diagnosis of the morphology of the root canal system is a prerequisite for successful root canal treatment.1 Frequently, root canals are left untreated because the clinicians fail to identify their presence, particularly in teeth that have an anatomical variations or additional root canals.2 Supernumerary root is a developmental condition and may involve any tooth. The incidence of ...
