Drought stress amelioration in tomato (Solanum lycopersicum L.) seedlings by biostimulant as regenerative agent

Acclimation to Drought Stress Enhances Oxidative Stress Tolerance in Solanum lycopersicum L. Fruits

A moderate water deficit stress (S1) applied 10 days after anthesis was found to induce acclimation to a subsequent more severe drought stress (S2) in Solanum lycopersicum L.. When plants were pretreated with S1, and then subjected to S2, fruit water status remained similar to controls. In contrast, S2 induced a decrease in both parameters of water status and diameter of fruits from non-acclima...

Comparative study of salt stress-induced physiological and molecular responses in tomato (Solanum lycopersicum L.)

Effect of Blue Light on Endogenous Isopentenyladenine and Endoreduplication during Photomorphogenesis and De-Etiolation of Tomato (Solanum lycopersicum L.) Seedlings

Light is one of the most important factor influencing plant growth and development all through their life cycle. One of the well-known light-regulated processes is de-etiolation, i.e. the switch from skotomorphogenesis to photomorphogenesis. The hormones cytokinins (CKs) play an important role during the establishment of photomorphogenesis as exogenous CKs induced photomorphogenesis of dark-gro...

EFFECT OF RATE OF ARBUSCULAR MYCORRHIZA INOCULUM ON TOMATO (Solanum lycopersicum) SEEDLINGS

An experiment on the effect of rate of Arbuscular mycorrhiza (AM) inoculum on tomato seedlings was conducted at Bangladesh Agricultural Research Institute, Joydebpur, Gazipur, Bangladesh for two consecutive years. Seven rates of AM inoculum viz., 0, 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0 kg/m were tested. Cowdung was used at a rate of 5 kg/m. Seeds were sown in 10 cm apart lines on 13 November 2007 a...

In-Vitro Organogenesis in Tomato (Solanum Lycopersicum) Using Kinetin

This research was undertaken for optimizing simple and reproducible protocol on indirect regeneration in tomato using kinetin. The effect of kinetin for efficient callus production was studied and its results were interpreted. Hypocotyls and cotyledons were used as explants and effect on callus derived regeneration was greatly influenced by addition of kinetin in media. The individually positio...
