Abstract:: Four aspects of factors influencing the accuracy of nondestructive chlorophyll (Chl) and nitrogen (N) measurement in fresh leaves were studied: (1) optimum wavelength (OW) identification; (2) indices development and evaluation; (3) influence of leaf properties; and (4) influence of meter parameters and sampling technique. Results were used to develop indices...

Abstract:: The effect of increased manganese superoxide dismutase (Mn-SOD) and cytosolic ascorbate peroxidase (cAPX) on various abiotic stresses was studied using transgenic tomato (Lycopersicon esculentum) plants. Transformants were selected in vitro based on kanamycin resistance, confirmed by PCR and northern blot analyses. Northern blots showed an enhanced gene expression of Mn-SOD...

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...

Abstract:: Roots of greenhouse-grown peppermint (Mentha piperita L.) and spearmint (Mentha spicata L.) plants and in vitro-grown shoot cultures were inoculated with Verticillium dahliae conidial suspensions to study symptom development, detection, and elimination of the V. dahliae. There were significant differences in the symptom expression of control and infected shoot cultures...

Abstract:: Bacterial contamination is one of the most important problems both in plant tissue culture research and commercial laboratories. Early detection of contaminants saves time, effort, and money. Strawberry runner explants were screened for contaminants during June to August, 1994 and 1995. Most contaminants found were bacterial rather than fungal. Bacterial...

Creator:: Chang, Yongjian
Abstract:: Alternating temperature (22°C / -1°C) pretreatments were effective for increasing cold hardiness and recovery of cryopreserved meristems. Combining low temperature pretreatment with abscisic acid (ABA) or sucrose treatments reduced the time required for optimal cold hardiness of meristems. Desiccation tolerance was directly correlated with increased cold hardiness and recovery of...
