  • Vegetative propagation of the filbert (Corylus avellana L.) by means of budding and cuttings

    Creator:
    Hubert, Gregory E.
    Abstract:
    Several variations of budding and cutting propagation methods were tested for use with filberts. Both summer budding and chip budding attempts were generally unsuccessful. However, the results of employing measures to retard desiccation of buds and increase callusing rates indicate possibilities for future success. Numerous sheathing, wrapping and sealing materials...

  • The use of 2, 4-d, paraquat and dinoseb for control of filbert (Corylus Avellana L.) suckers

    Creator:
    Reich, Jack Ernest
    Abstract:
    The control of filbert (Corylus Avellana L.) suckers by means of herbicides was investigated in three phases during 1968 and 1969. (1) Screening trials, on canned filbert trees in the greenhouse, to determine the effectiveness of various herbicides and concentrations in controlling vegetative growth. (2) A summary experiment in the...

  • Influencing flower initiation and flower cluster set in the 'Barcelona' filbert with growth regulators

    Creator:
    Romines, Marsha Lynn
    Abstract:
    The alternate bearing cycle in the 'Barcelona' cultivar poses a major problem to the filbert industry. This study was conducted to alleviate this problem in one of two ways: by (1) increased floral initiation in the "on" year, and (2) increased cluster set in the "off" year. Growth regulators were...

  • Aspects of manganese nutrition in filbert trees

    Creator:
    Silberman, Ricardo S.
    Abstract:
    Lime was applied at different rates to filbert trees grown in containers in an acid soil. As lime application rate increased, the leaf Mn and extractable soil Mn were significantly reduced. In control trees leaf Mn was over 1300 ppm, but no growth reduction or Mn toxicity symptoms were found....

  • An analysis of the effects of Boron and plant growth regulators on flower development in Filbert, Corylus avellana L.

    Creator:
    Kelley, John Roberts
    Abstract:
    Three distinct stages of flower cluster abscission were identified prior to fertilization: flowers which did not begin development (stage 1), flowers which had begun development (stage II) and clusters which had begun to form distinct nuts (stage III). Abscission of stages I and II coincided with a rapid increase in...

  • Cryopreservation of pollen

    Creator:
    Craddock, W. James Hill
    Abstract:
    Cryopreservation of pollen offers a simple and effective method of long-term pollen storage. Pollen may be stored in liquid nitrogen (LN) for many years without loss of its essential capabilities to pollinate, fertilize, and set normal fruit and seed when used in plant breeding, for controlled pollinations, or for the...

  • The translocation of ethephon and its physiological effects on the filbert (Corylus avellena L.) during husk senescence

    Creator:
    Kwong, Francis Y.
    Abstract:
    Nut drop in the filbert is a consequence of the senescence of the husk. It is possible to accelerate this process by the application of ethephon (2-chloroethyl)phosphonic acid after the nut has abscised from the base of the husk. This study is an investigation on the physiological effects of the...

  • Propagation of the filbert, Corylus avellana L. by seedage and graftage

    Creator:
    Nussbaum, Emily S.
    Abstract:
    The filbert is propagated by layerage and a faster method is needed to keep pace with the rapidly expanding industry and the demand for new cultivars. Propagation by seedage and graftage were the two methods selected for evaluation in the research. Seed experiments were initiated to identify optimum treatments for...

  • Effect of boron on seven vegetable crops grown on two soil types

    Creator:
    Oneida, Kelly Ann
    Abstract:
    Boron deficiency or toxicity can reduce yield and quality of vegetables. Seven vegetable crops, varying from low to high boron requirements were grown in field plots at Corvallis in 1987. Leaf-B and yield components of green bean, cucumber, potato, carrot, tomato, broccoli and table beet were examined under conditions of...
