structure. So, it is possible to achieve the salinity-tolerant genotype in plants through creating changes in the genetic structure and breeding activities. Tomato is in the group of plants sensitive to salinity stress. Distinct studies have been explained different indicators for tolerance to salt stress in tomato. Identifying a reliable indicator in the early stages of plant growth under salt...

Growth of flue-cured tobacco as influenced by Meloidogyne javanica and the effectiveness of DD and ethoprop to manage this nematode were evaluated over two growing seasons. Populations of M. javanica, root galling, plant height, steam crown diameter, whole plant weight, and yield were monitored at approximately 2-week intervals beginning 28 days after transplanting. Treatment influence on nemat...

shoot:root ratio, dry matter partitioning, growth analysis, and water use efficiency of oat (avena sativa l., cv. walker) was investigated under excessive nitrogen (n) as 200 mg n kg-1 (n1p0), excessive phosphorus as 200 mg p kg-1 (n0p1), and combined 100 mg n+100 mg p kg-1 (n2p2), and the control (n0p0) as check in a pot experiment at dryland agriculture institute, west texas a and m universit...

Soil salinity poses considerable and increasing problems for agriculture, and is receiving much attention from plant breeders. The identification of genes whose expression enables plants to adapt to and/or tolerate salt stress is essential for breeding programs, but little is known about the genetic mechanisms of traits in saline conditions. The data obtained from 75 families produced by crossi...
