Physiological and morphological traits of flag leaf play important roles in determining crop grain yield and biomass. In order to understand genetic basis controlling physiological and morphological traits of flag leaf, a double haploid (DH) population derived from the cross of Huaai 11 × Huadamai 6 was used to detect quantitative trait locus (QTL) underlying 7 physiological and 3 morphological traits at the pre-filling stage in year 2012 and 2013.

Maintaining and managing trees with different ecological plasticity under climate conditions aggravated by short-term variability are major challenges for foresters. Our aims were to investigate species-specific ecophysiological responses of canopy trees in a mixed Turkey oak forest during their early-phase regeneration. We measured plant carbon and water exchange with portable IRGA equipment under natural field conditions (canopy gap) and in a climate-controlled (standardized) environment.

Understanding the complexity of the vine plant’s response to water deficit represents a major challenge for sustainable winegrowing. Regulation of water use requires a coordinated action between scions and rootstocks on which cultivars are generally grafted to cope with phylloxera infestations.

The crop has a great potential in future due to respected increase in demand for forskolin widely used in glaucoma, cardiac problem and also used in treatment of certain type of cancer (Shah et al., 1980). Plant growth regulators are group of naturally occurring, organic substances which effect growth processes at minute concentration, synthesized at one plant part and are capable of translocation to site of its action and regulating one or more physiological activity like Photosynthesis rate, Stomatal conductance, Co2 utilization (ppm) and H2O utilization.

Although, protective cultivation (in soil or soilless media) offers a favorable environment for crop growth, development and consequently, results in higher productivity. However, numerous factors viz. temperature, relative humidity, radiation, evapotranspiration (crop water requirement) vapour pressure deficit, plant stomatal conductance, irrigation, fertigation, disease incidence, leaf wetness duration, electricity cost, diesel fuel cost and labor cost affect the greenhouse cucumber production to a significant degree.

The major production constraint for okra is yellow vein mosaic disease, causing losses with regard to the quality and as well as the yield. This is a viral disease occurring on bhendi. Yellowing of the entire network of veins in the leaf blade is the characteristic symptom. In severe infections, the younger leaves turn yellow to become entirely chlorotic and the plant is highly stunted.

The cytokinin production and transport from root to leaves is hindered under water stress causing leaf senescence due to the synthesis of hydrolytic enzymes. A part of stress effect may be linked to the regulation of osmotic solutes and maintenance of turgidity for stomatal conductance, photosynthesis and protein synthesis accompanied with reduced peroxidation of chloroplast and mitochondrial membranes in pearl millet under kinetin and cycocel treatments.

In the changing climate scenario, drought could be continued as a major abiotic limitation for crop productivity. Finger millet although known for its drought tolerance, the drought stress decreases the grain yield from 25 to 100 percent depending on the duration and magnitude of drought stress. Present study was conducted to explore the genetic variability of selected genotypes over the ruling varieties if any, based on the extent of reduction in grain yield, and dependent photosynthetic traits due to moderate drought stress for 18 to 20 days (grand growth to flower primordial initiation).

Present study was conducted at TVCC, LUVAS, Hisar on Twenty-four dogs irrespective of age, breed, sex affected with canine transmissible venereal tumour (TVT). Affected dogs were divided equally into three groups on the basis of treatment with chemotherapeutic drugs viz. vincristine therapy (Group I) and doxorubicin therapy (Group II and III). Vomition, diarrhea, alopecia, allergic nodules and stomatitis were adverse effects of chemotherapy in TVT affected dogs.

Triacontanol is a natural plant growth regulator for fruit plants. Tricontanol is used to enhance the growth, chlorophyll content, photosynthesis, transpiration, stomatal conductance and uptake of nutrient in different fruit crops. Tricontanol increases the amino acids, sugars and carbohydrates in plants. It also influences other metabolic processes in different fruit crops.
