Application of [(14)C]fructosyl sucrose was used to determine whether sucrose cleavage was necessary for sucrose uptake by sugarcane (Saccharum spp.) internode tissue. Although approximately 25% of (14)C in the apoplast was present as fructose, indicating some sucrose cleavage, less than 15% of the label was randomized in the sucrose that remained in the tissue after a 30 minute osmoticum rinse...

An important goal in developing functional-structural plant models (FSPMs) is a reliable and adequate description of the inherent interactions between processes controlling plant growth and formation of plant architecture. Several architectural models have been introduced for specific crops using temperature-driven descriptive models based on the phyllochron / plastochron philosophy (Dornbusch ...

Some quantitative aspects of the demyelinating lesion, and its progress, produced by the in vivo injection of lysophosphatidyl choline (LPC) into the myelinated peripheral nerves of adult mice have been investigated. The extent of the lesion has been shown to be highly localized to the injection site and dependent on the concentration of LPC. The length of the demyelinating zone appears to be d...

In rat sciatic nerves, a small bundle of fibers was identified in which myelin sheaths were absent at birth, appeared within 3 days, and grew rapidly for 2 wk. During this interval, nerves were removed from littermates and were sectioned serially in the transverse plane. Alternating sets of thin and thick sections were used to prepare electron micrograph montages in which single myelinating axo...

Sainfoin (Onobrychis viciifolia Scop.) is a perennial forage crop with desirable properties adapted to temperate climate conditions. The purpose of this research was study the phenotypic correlation coefficients between dry yield and some morphological traits, identify direct indirect effects associated traits. Thus, 32 ecotypes (landraces) were assessed in randomized complete block design layo...

Abstract Peanut improvement is limited by a narrow genetic base. However, this obstacle can be circumvented incorporating phenotypic variability from wild, diploid Arachis species through interspecific hybridizations. In study, four allotetraploid hybrids IpaCor 4 x ( A. ipaensis × correntina ) , IpaDur duranensis ), IpaSten stenosperma and ValSten valida were created morphologically characteri...

Abstract. Dwiati M, Widodo P, Susanto AH. 2023. Shoot regeneration in Nepenthes mirabilis as affected by flurprimidol and GA3 application. Biodiversitas 24: 4168-4174. (Lour.) Druce. is a pitcher plant species at higher risk of extinction mainly due to overexploitation. Previous investigations have shown that vitro micropropagation can be used an approach for ex-situ conservation N. mirabilis. ...

Three different invertases are found in the developing internodes of oat (Avena sativa cv. Victory). Two soluble invertases (I and II) are separable on diethylaminoethylcellulose and Sephadex columns. They are further distinguished by their kinetic constants, heat stability, and differences in stability and apparent activity optima in response to pH treatments. Relative activities of the two so...
