Preplant soil applications of oxamyl to shade grown tobacco in Globodera tabacum-infested field soil increased green leaf yields over untreated plots by 10.7 and 21.0% for 2.2 and 6.7 kg a.i. oxamyl/ha, respectively. Green leaf yield was negatively correlated (r = -0.60, P = 0.04) with initial G. tabacum density, which ranged from 33 to 154 second-stage juveniles (J2)/cm(3) soil. Numbers of G. ...

A study of the effects of different steroids on germination and tube growth of tobacco pollen (Nicotiana tabacum L. cv Petit Havana SR1) matured in vitro is presented. Application of the mammalian steroid sex hormones (testosterone, progesterone, and estradiol) resulted in a stimulation of pollen germination and tube elongation. The presence of both steroids and flavonols in the germination med...

When tobacco (Nicotiana tabacum L.) cultured cells (line BY-2) at the stationary phase were transferred to culture medium that contained cytokinin (benzyladenine) instead of auxin (2,4-dichlorophenoxyacetic acid), proplastids in the BY-2 cells were converted to amyloplasts within 48 h. The data obtained from in vitro transcription assays using isolated plastid-nucleoids (nuclei) strongly sugges...

The study was conducted to compare between nine cottonseeds genotypes (Gossipum hirsutum L) which included, two locale Iraqi Coker 310 and Lachata are three of the Bakhtegan, Khordad, Varamin from Iran, four them Cafko, Dunn 1047, Montana, Stoneville America (USA) on fiber quality. field experiment designed with randomised complete block design using replicates in Grdmal village, south Erbil, i...

Stem and root tumors and teratomata may be induced in tobacco plants (Nicotiana tabacum L., var. One Sucker) by total debudding. Intact plants or plants only decapitated produced no tumors or teratomata throughout their life time. These findings suggest a possibly important oncological relationship between normal growth and tumorous growth. Prevention of normal regeneration (apical and axillary...

Among the modern computational techniques, Artificial Neural Network (ANN) and Adaptive Neuro-Fuzzy Inference System (ANFIS) are preferred because of their ability to deal with non-linear modelling complex stochastic dataset. Nondeterministic models involve some complexities while solving real-life problems but would always produce better outcomes. For first time, this study utilized ANN ANFIS ...

Abstract Plant tolerance to aluminum (Al) toxicity can be enhanced by an ectomycorrhizal (ECM) fungus through biological filtering or physical blockage. To understand the roles of ECM colonization in Al absorption with regard tolerance, Pinus massoniana seedlings were inoculated either Lactarius deliciosus (L.:Fr.) Gray isolate 2 Pisolithus tinctorius (Pers.) Coker et Couch 715 and cultivated a...
