Triplicated determinations of all samples were analyzed. In red colored fruits juice, a decreasing trend of titratable acidity, ascorbic acid and TDS was found with increasing pattern of sugars, TSS and pH. Similarly in peel, less chlorophyll and more carotenoids were recorded in red colored fruits. Total phenolic contents in juice remained constant with declining trend in peel from green to red colored fruits. In juice both flavonoids and flavonols were constant while in peel flavonols increase was noted in red colored fruits. Total anthocyanins showed an increasing trend in red colored fruit for both, the peel and juice. Antioxidant activity was increased in juice and decreased in peel for red colored fruits. Nutritional values of green color peel fruits are alike those of red colored, but less sugars, reduced sweetness were duly noted regarding their domestic consumers acceptance.

Due to its nutritive importance, it ranks as fourth after rice, wheat and maize in the world. However, production of the crop is far below the average due to poor crop stand, soil fertility and water management practices. There is a strong need for improvement in the fair yield of potato through managed production techniques and best soil nutrient combinations. To find out the best combination of fertilizer level of NPK on growth, yield and quality of the potato crop, nine field experiments on potato crop were conducted at Rawalpindi division, Punjab Pakistan for three successive Rabi seasons during 2014-2017. Treatments consisted of four levels of N (244, 300, 356 and 412 Kg N ha-1), P (163, 200, 237 and 275 kg P ha-1) and K (136, 167, 198 and 229 Kg K ha-1) laid out in Randomized Complete Block Design (RCBD) with three replications. Results showed that there was no significant difference of location in terms of yield (T ha-1). However, mean data showed that the fertilizer combinations significantly (<0.05) affected yield and yield components of the potato crop. Among the treatments, NPK level (412, 275 and 229 Kg ha-1) gave maximum (100 tuber m-2), potato yield (3.2 Kg m-2), dry matter (1.3 Kg m-2), while the least number of tuber m-2 (63), potato yield m-2 (2.02 Kg), dry matter yield m-2 (0.9 Kg) were recorded where combination NPK (244, 163and 136 Kg ha-1) were applied.

But the main problem that occurs in gladiolus is that it has short vase life. The present experiment was conducted with an objective to investigate the effect of four preservative solutions [distilled water, Sucrose (3%), AgNO3 (250 ppm), AgNO3 (250 ppm) + Sucrose (3%)] and packaging material on postharvest quality of three gladiolus varieties, “Tissue, White Prosperity and Alexandra”. Packaging material consists of control treatment (without packaging), packaging of cut spikes with 100 ppm acetic acid soaked cotton and packaging of polyethylene sheet after sucrose pulsing. The experiment was arranged as two factorial laid out according to completely randomized design (CRD) having three replications. Results showed that preservative solution having combination of AgNO3 (250 ppm) + Sucrose (3%) significantly improves days to open basal floret, floret opening percentage (%), bloom spread (inch), floret length (inch), floret diameter (inch), fresh spike weight (g), dry spike weight (g), fresh weight loss (%) and vase life (days). Moreover, this treatment was also effective in reducing the wilting (%) in all gladiolus varieties. However, for solution uptake (mL/spike) and solution balance (ml/spike), AgNO3 (250 ppm)alone gives the best results. For packaging treatment, the pulsing of a cut spike with 20% sucrose followed by polyethylene sheet wrapping proves to be effective.

Specific primers were used to amplify (Mtco1 gene) in Diaphorina citri and also Las specific primers were also used to detect HLB pathogen. Amplified fragments of 507bp, 1500bp and 2500bp were observed in CLas and Mtco1 gene of Asian isolates. The resulted fragments were TA cloned and sequenced from both strands.

There is an increasing interest for use of mycoviruses as novel biocontrol agent as they reduce the virulence of their phytopathogeinc fungal hosts. Mycoviruses can also infect endophytic fungi and encode killer toxins. Better understanding of mycoviruses assembly, function, and evolution have been done through their structural analyses. Recent report on virus taxonomy suggested that mycoviruses genome mostly consists of double-stranded RNA (dsRNA), and about 30% of mycoviruses genome is composed of a positive, single-stranded RNA (+ssRNA).
