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...

Characterization of an architectural mutant of bean (Phaseolus vulgaris, L.)

Creator:: Guner, Nihat
Abstract:: Genetic and morphological characteristics of an architectural mutant in common beans were studied. The mutant had shiny, dark green leaves, overlapping leaflets, short petioles and a reproductive terminal bud even though the line did not carry the fin gene. Branching was nearly absent resulting in a single stem vine. This...

Soil temperature suppression on growth and yield of potato (Solanum tuberosum L.) in warm climates of Sri Lanka

Creator:: Tharmarajah, S. K.
Abstract:: Potato (Solanum tuberosum L.) is one of the most productive and nutritious food crops. Due to its adaptability to cool climates, production in Sri Lanka has been restricted to erosion-prone highlands. Vast potential exists for expansion of potato cultivation in the lowlands while production areas in the highlands are limited...

Early detection of weed resistance : pattern-thinking and rapid microcalorimetric assay

Creator:: Suwanagul, Duangporn
Abstract:: Weed resistance is usually diagnosed after a weed control practice has lost efficacy and weed populations begin to increase rapidly. Prediction and validation in the field at a very early stage of resistance development is a promising method for preventing an uncontrollable problem. Pattern-thinking helped individuals connect their experience of...

Relationships of ammonium and nitrate status with inflorescence necrosis in 'Pinot noir' grapevines

Creator:: Gu, Sanliang
Abstract:: Inflorescence necrosis (IN) is a recently described disorder in grapes characterized by partial or complete deterioration of the pedicel and rachis near bloom. Elevated levels of ammonium in the rachis are associated with the incidence of IN and hypothesized as the cause of the disorder. An incubation system with single-node...

Role of surfactants in foliar uptake of plant growth regulators

Creator:: Tan, Siyuan
Abstract:: Penetration of ¹⁴C-labeled plant growth regulators into the surface of apple (Malus pumila M.) leaves pre-soaked in 10 ml I⁻¹ solutions of surfactant was measured by detecting changes in radioactivity of the solution in glass cylinders sealed to the astomatal, adaxial surface of the leaf discs. Penetration of 2,4-D [(2,4-dichlorophenoxy)acetic...

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...

Hydrogen cyanamide on triphenyltetrazolium chloride reduction, sulfhydryl group binding, and catalase activity in bromegrass (Bromus inermis Leyss) cells

Creator:: Zhen, Liping
Abstract:: Hydrogen cyanamide (CY) has been used to break rest in temperate crops, but levels used to overcome rest are sometimes toxic to plants. The rest breaking effect of CY is thought to involve peroxide metabolism. Inhibition of catalase by CY has been proposed as a mechanism for overcoming dormancy in...

Interaction of crop plant population with weed competition in corn (Zea mays L.), bush snap beans (Phaseolus vulgaris L.), and onion (Allium cepa L.) at differing stages of development

Creator:: Williams, Clarence Frank
Abstract:: Yield reductions due to competition of weeds with crop plants can be extremely important. Early weed competition can be as important in reducing crop yield as weed competition for the entire season. The objectives of this study were (1) to determine the weed control achieved by narrow row-cropping patterns, (2)...
