Polyamine patterns in haploid and diploid tobacco tissues and in vitro cultures BABT
Carone,Sílvia Bicudo; Santa-Catarina,Claudete; Silveira,Vanildo; Floh,Eny Iochevet Segal.
The aim of this work was to determine PAs levels in pith tissues and callus cultures from haploid and diploid tobacco plants, explanted from the apical and basal regions of the stem. These explants were cultured in an RM-64 medium supplied with IAA and kinetin, under light or in the dark, during successive subcultures. PAs levels followed a basipetal decrease in diploid and an increase in haploid, pith tissues. A similar pattern of total PAs (free + conjugated) was observed for the callus of diploid and haploid plants maintained in the light, and for the haploid callus in the dark, whereas the diploid callus in the dark showed a constant increase in total PAs levels until the end of culture. The PA increase in the diploid callus in the dark was related to...

The application of polyamines and self-incompatibility control substance on yield indices and qualitative traits of apple cv ‘Red Delicious’ Biological Sciences
Sayyad-Amin, Pegah; Davarynejad, Gholamhossein; Abedy, Bahram.
  Among the main problems of some temperate fruit species, such as the apple tree (Malus domestica), are the poor set of fruits and low production. Polyamines and Self-Incompatibility Control Substances (SICS), involving mineral nutrients such as manganese and boron, are the major chemical compounds used to reduce these problems. The aim of this study was to use popular polyamines putrescine (Put) at 0.1, 0.25 mM, spermine (Spm) and spermidine (Spd) both at 0.05, 0.25 mM and SICS at 1, 2 mg L-1, alone or with cotton coverage bags and control to show the effects of these chemical compounds on yield indices and qualitative traits of apple (Malus domestica) cv ‘Red Delicious’. Results showed that Spd (0.25 mM) and SICS (1 mg L-1) had higher effect on yield...

Variação nos níveis de prolina, diamina e poliaminas em cultivares de trigo submetidas a déficits hídricos. Repositório Alice
FUMIS, T. de F.; PEDRAS, J. F..
O objetivo deste trabalho foi avaliar duas cultivares de trigo (Triticum aestivum L.) Anahuac e IAC-24, cultivadas em solo arenoso, sob três regimes de umidade do solo (-0,027 a -0,1 MPa; -0,027 a -0,045 MPa; e -0,027 MPa - irrigação constante). Foram analisadas as variações nos níveis de prolina, da diamina (putrescina) e das poliaminas (espermina e espermidina) e o teor relativo de água (TRA) durante o perfilhamento, emborrachamento, floração e no enchimento dos grãos. Nas plantas submetidas a déficits hídricos foi verificada menor TRA e acúmulo de prolina e putrescina; em relação às poliaminas não foram observadas diferenças entre os tratamentos. Nos tratamentos sob déficit hídrico, a cultivar IAC-24 apresentou teores mais elevados de prolina e...

ผลของการฉีดพ่นสเปอร์มิดีนต่อคลอโรฟิลล์ฟลูออเรสเซนส์ ปริมาณโพรลีน และการรั่วไหลของอิเล็กโทรไลต์ของใบข้าวเหนียวดำภายใต้สภาวะเค็ม Thai Agricultural

Saline soil is a major problem that affects growth and productivity of rice. Spermidine (Spd), a member of polyamine (PA), is a plant growth regulator playing essential roles in protecting many crop plants under salinity stress. The objective of this study was to explore the roles of exogenous spermidine in protecting salt-stressed rice plants by evaluating its effects on three physiological indicators of plant stress. Two black glutinous rice cultivars (Oryza sativa L. spp. indica), including cv.Gs.no.00621(salt tolerant) and cv. LLR-039 (salt sensitive) were grown in potted soils until early booting stage. The plants were then arranged into three treatment groups including 1) control 2) 25 mM NaCl and 3) foliar application with 1 mM Spd prior to exposure...
