Improvement of cryopreservation regrowth of in vitro Ribes by pretreatment

Creator:: Luo, Jie, 1968-
Abstract:: Improved recovery of cryopreserved meristems and calli from in vitro currant (Ribes aureum Pursh and R. ciliatum Humb. & Bonpl.) plants was obtained by two-hour pretreatment with sucrose, proline, abscisic acid-responsive protein (RABP), and bovine serum albumin (BSA) solutions. Meristems and calli cold-acclimatized for one week were immersed in pretreatment...
Resource Type:: Masters Thesis
Full Text:: only a few degrees of cold tolerance were achieved. Quatrano (1968) first reported cryopreservation

Physiology of ripening in pears

Creator:: Wang, Chien Yi
Abstract:: Investigations were conducted to study in detail some biochemical and physiological aspects of ripening in pears. Anjou pears picked at different degrees of maturity were treated with Ethrel (2-chloroethane phosphonic acid), 4000 ppm, and ethylene, 500 ppm, for different lengths of time. Respiration rate was measured twice daily and changes...

Boron nutrition and fruit set of 'Italian' prune

Creator:: Hanson, Eric J.
Abstract:: Foliar B sprays have increased fruit set in 'Italian' prune (Prunus domestica L.) by 2 fold in some trials and had no effect in others. This work was conducted to identify reasons for this inconsistent response. Since B levels in flowers are associated with the amount of fruit set, factors...

The inheritance of ten quantitative characteristics in sweet corn (Zea mays L.)

Creator:: Hansen, Leon Afton
Abstract:: The inheritance of ten characteristics of sweet corn was studied by quantitative genetic analysis. Characters studied were tassel date, silk date, plant height, ear height, shank length, husk extension, tip blanking, number of kernel rows, ear length, and weight of the first ear. Diallel crosses were made between seven inbred...

Effect of crop load on mineral uptake and partitioning in D'Anjou pears

Creator:: Meddouri, Messaoud
Abstract:: Three thinning levels were applied to twenty-five-year-old D'Anjou pear trees in a completely randomized design with five single-tree replicates on June 2, 1985. Samples of wood, shoot leaves, shoot twigs, spur leaves, spur twigs and fruits were taken every month during the season of growth for mineral analysis. Sampling an...

Effect of crop density on vegetative and fruit growth and on mineral status in Nijiseiki pear (Pyrus pyrifolia)

Creator:: Gu, Sanliang
Resource Type:: Masters Thesis

Calorimetric study of the respiratory metabolism of peach (Prunus persica L. Batsch.) seeds during stratification and its relationship to seedling growth

Creator:: Moreno-Simunovic, Yerko M.
Resource Type:: Dissertation
Full Text:: larch clones by calorimetric measurements of metabolic heat rates has been studied (Hansen et al

The interaction of photosynthesis and auxin transport during adventitious root formation in Pisum sativum L. stem cuttings and the effect of stock plant etiolation on rooting

Creator:: Kumpula, Carol L.
Abstract:: Adventitious root formation can be inhibited in stem cuttings of Pisum sativum L. (pea), an easy-to-root species, if the apical and lateral buds are removed. Application of exogenous auxin to the apical stump can replace the rooting stimulus produced by the buds. Root number was reduced by 50 to 100%...

Water partitioning and respiration activity of dormant grape buds

Creator:: Gardea, Alfonso A.
Abstract:: Dormancy of 'Pinot Noir' grapevines was characterized. Primary buds required ca 300 cumulative chilling hours (CCH) to initiate the transition from endodormancy to ecodormancy, which occurred in mid November. Additional chilling, up to 1000 CCH, improved budbreak. Changes in bud water content were estimated by gravimetric and spectroscopic methods. Total,...
