The objective was to evaluate the epicotyl length of seedlings soybean cultivars in field, submitted plant densification by reducing inter-row spacing. Two field experiments were conducted Rio Paranaíba state Minas Gerais and effect reduced spacing (20 cm, 30 40 cm 50 between rows) evaluated. assessment done using a millimeter ruler when plants reached V2 development stage. randomized block des...

In vivo spectrophotometry showed that the phytochrome concentration in pea epicotyl hooks decreased at a constant rate for 4 hours when the tissue was exposed to continuous red light. Thereafter the rate slowed progressively so that a steady concentration of phytochrome was approached at hour 7. Returning the plants to darkness resulted in an increase in phytochrome due to the apparent synthesi...

Histones from the epicotyls of light-grown dwarf peas (Pisum sativum L. cv. Little Marvel) which had been treated with gibberellic acid were compared to histones from control dwarf peas by the method of polyacrylamide gel electrophoresis. The histone complements were found to be unaltered in the electrophoretic mobility and relative quantity of the individual fractions. The ratio of histone to ...

Various growth and physiological parameters were measured in germinating, presenescent, and senescing soybean (Glycine max [L.] Merr.) cotyledons and in cotyledons rejuvenated by epicotyl removal 18 days after planting. The maximal measured carbon dioxide exchange rates (CER) in the cotyledons were in the range of those reported for field-grown soybean leaves. Rejuvenated cotyledons accumulated...

Penyambungan (grafting) merupakan salah satu upaya untuk memperbaiki sifat tanaman menggunakan bahan klonal baik pada fase pembibitan, pemeliharaan maupun rehabilitasi. Keragaan kopi Robusta dapat diperbaiki melalui penyambungan intraspesifik (Robusta/Robusta) menghasilkan produktivitas yang lebih tinggi atau interspesifik (Arabika/Robusta) Arabika. Tujuan penelitian ini adalah (1) mengetahui p...

Gamma radiation-induced graft copolymerization of styrene onto poly(ethylene terephthalate) (PET) films was studied using simultaneous irradiation technique. The effects of grafting conditions on the degree of grafting were investigated. The grafting conditions include monomer concentration, irradiation dose, dose rate, and the type of solvent. Moreover, the effect of the addition of crosslinki...

background: dialysis patients frequently have coronary artery disease but are regarded as high risk patients for coronary artery bypass grafting (cabg). methods: between february 2002 and september 2006, seventeen dialysis-dependent patients underwent isolated cabg at our center. cabg was performed under cardiopulmonary bypass (cpb) for all the patients. all cases had been maintained on hemodia...

We show that an instanton with high charge can provoke the creation of extra curvature on space holds it. Geometrically, this corresponds to a new surgery operation, which we name grafting. Curvature around sphere increases by grafting when decays.

The production of ethylene by etiolated pea epicotyls (Pisum sativum L., cv. Alaska) is confined to the plumule and plumular hook portion of the epicotyl, and occurs at a rate of about 6 mul.kg(-1).hr(-1). Such a rate is sufficient to give physiologically active concentrations of ethylene within the tissue. Exposure of etiolated seedlings to a single dose of red light caused a transient decreas...

A gene (EGLI) encoding an endo-p-l,4-~-glucanase (EGase, EC 3.2.1.4) of pea (Pisum sativum) has been cloned and characterized. EGL 1 encodes a 486-amino acid polypeptide, including a 24-mer putative signal peptide. The mature protein has a calculated molecular mas of 51.3 kD and an isoelectric point of 9.1. This pea ECase shares significant similarity with ECases from other plant species, but i...
