Water availability is a very important factor for the growth and development of plants, which limits the plant production capacity. Rootstocks are widely utilized to improve plants tolerance to various biotic and abiotic stresses. In this study, physiological and biochemical responses of fifteen almond rootstock candidates to drought stress were investigated under in vitro conditions. The shoot tips from fifteen almond rootstock candidates were cultured in MS medium containing 1.0 mg/L BAP, 0.01 mg/L IBA, 30 g/L sucrose and 7 g/L agar.

Vitamins are regarded as vital growth substances. They act as cofactors of various key enzymes involved in metabolism and also have vital influence on metabolic activities of plants. They are believed to play a significant role in plants against abiotic stresses, particularly during water stress. The current experiment was conducted to evaluate the role of exogenously applied thiamin on two white clover cultivars, Super Late Fsd and Layalpur Late, at varying [100% (control), 80%, and 60% field capacities] water regimes.

The rapid growth of the population produces a massive quantity of domestic wastewater including a lot of pathogenic bacteria. Hence, removing bacteria in wastewater is becoming a large environmental problem. Membrane bioreactor (MBR) was considered as an effective method to remove microorganisms without creating dangerous substances.

Pigeon crop has the unique ability to produce a nutrient rich substance termed pigeon ‘milk’ (PM), which has functional resemblance with the mammalian milk. Previous researches have demonstrated that a large number of exosomes and exosomal miRNAs exist in mammalian milk, and many of them are associated with immunity, growth and development. However, to date, little is known about the exosomes and exosomal miRNAs in PM.

There are numerous disadvantages of chemical fertilizer as the soil can take really long to replenish and attain its natural form. Soil need to be fit as it is most important factor for growth of plant. Due to the decrease in soil quality farmers have started using alternate substances such as biofertilzers which provide right amount of nutrients and are eco-friendly.

Antitranspirants are the compounds or the substances applied to the leaves of the plants for the purpose of reducing water loss (transpiration) without causing a momentous change in the various important processes of the plant such as growth and photosynthesis. Antitranspirants are generally classified into four distinct categories viz., stomatal closing type, filmforming type, reflecting type and growth retardant.
