The bandwidth of membrane current measurements in potential-clamped Ranvier nodes is limited by the low-pass filter properties of the internodes. If about 35% of the current measuring internode is grounded via an additional electrode, the bandwidth of this internode increases by a factor of about 40. Consequently, in potential clamp experiments the measured time course of the early ionic curren...

Rhizome growth and development is regulated by phytohormone. However, endogenous phytohormones affect rhizome initiation, sustained in perennial grass species remains elusive. In this study, we investigated the morphological characteristics content of indole-3-acetic acid (IAA), zeatin (ZT), gibberellic (GA3), abscisic (ABA) rhizomes two different Kentucky bluegrass. Using ultra-performance liq...

– 8 – In 1993 and 1994, many crosses were made with the goal of developing rootstocks with broad and durable nematode resistance, while improving horticultural characters such as rooting ability and shoot length. The parents of these crosses included a number of grape species known to be highly resistant to both root-knot and dagger nematodes. They included several forms of Vitis arizonica, V. ...

St. Augustinegrass is a widely used turf and pasture grass in the southern US. Raleigh is a cultivar known for superior cold tolerance than other St. Augustinegrass cultivars. However, its coarse-leaf texture and long internodes are undesirable when planted in home lawns. Mutagenesis by gamma ray irradiation was employed to treat node cuttings and calli for inducing semi-dwarf growth phenotype....

Excision of all leaves and buds of Coleus blumei Benth. plants reduced xylem cell and sieve tube regeneration a highly significant amount around a wound in internode number 5 when compared with regeneration in intact (wounded) plants. Application of indoleacetic acid (IAA-(14)C) to the cut surface of internode number 2 restores regenerative activity around the wound in internode number 5. Radio...

Lignin is one of the major characteristics of plant secondary cell wall that provides structural rigidity for the cells and tissues and hydrophobicity to tracheary elements. Internode tissues of Aeluropus littoralis as a halophyte grass were sampled at different developmental stages (from the first to the fifth internodes ) and under different NaCl concentrations. The influences of NaCl and int...

Abstract. This article establishes a system of anti-bud injury in sugarcane cutting based on computer vision using MATLAB software as a development platform. The seedcane cutter box cuts twice each turn. Match the accurate shutter trigger time interval according to the rotation speed of the cutter , the transportation speed of sugarcane, in order to make the position of collected image of the t...

Brief, low energy (approximately 400 Kerg cm(-2)) red light interruption of the early dark-growth period of Zea mays L. cv F-M Cross induced inhibition of first internode elongation which was maximal whenever light interruption occurred from 2.5 to 4 days of seedling age. Two-thirds of the maximal inhibition occurred in the tissues constituting the region 0 to 2 mm below the coleoptilar node at...

Ethylene (ET) is critical importance in the growth, development, and stress responses of plants. Plant hormonal stress responses have been extensively studied, however, the role of ET in plant growth, especially plant height (PH) remains unclear. Understanding the genetic control for PH in response to ET will provide insights into the regulation of maize development. To clarify the genetic basi...
