Tuberose (Polianthus tuberosa) is a commercially important cut flower; but its longevity and quality characteristics are compromised by stress during storage and transportation. Thus, it is important to determine the most appropriate preservative solution to best maintained cut flowers. Tests were done to examine the effects on of nano-silver (NS) (0, 15, 30 and 45 mg L-1) and sucrose (0, 4 and...

As sugar beet source leaves lowered the CO(2) concentration to compensation point in a closed atmosphere, leaf thickness and relative water content decreased. Leaf water potential declined rapidly from -0.5 to -1.4 megapascals. At 340 microliters CO(2) per liter, water potential and sucrose, glucose, and fructose contents were steady in photosynthesizing source leaves. Within 90 minutes after l...

plantlets grown in conventional tissue culture systems usually encounter physiological and anatomical abnormalities including inability to photosynthesize, low chlorophyll content, open stomata, lack of a cuticle layer in the leaf, abnormal xylem parenchyma etc. photoautotrophic and photomixotrophic systems could diminish these problems. the purpose of this study was to increase the chlorophyll...

The effect of bleomycin on the molecular integrity of SV40 DNAwas determined under various conditions by taking advantage of the fact that a single scission produced in such a superhelical form of DNAcould be clearly manifested by analysis of samples with centrifugation in alkaline sucrose gradients. Conditions were found where the reaction velocity, the rate of disappearance of the characteris...

Sugar beet (Beta vulgaris cv. Loretta) and rape (Brassica napus cv. Licolly) plants were exposed under equal dose conditions in closed fumigation chambers under two different ozone (O3) pattern: Var130 (17:00–09:00 h: 40 μg O3 m −3; 09:00–17:00 h: 130μg O3 m−3) and Var220 (16:0012:00 h: 40 μg O3 m −3; 12:00–16:00 h: 220μg O3 m−3). Control plants were exposed under carbon filtered air conditions...

The high-methoxyl pectin of citrus was used to prepare a fat substitute and applied the processing technology moon-cake skin. physical, chemical, sensory properties substitutes prepared skins were studied by selecting texture properties, rheological water distribution, water-holding capacity. Results showed that gel hardness glucan–sucrose (G-SG) (glucan/sucrose = 4:6) as synergistic 6.23 ± 0.1...

BACKGROUND Osmotic dehydration is a process of the partial removal of water which is based on immersion of material having cellular structure in a hypertonic solution. Osmotic dehydration is used as a pretreatment for the dehydration of foods before they are subjected to further processing such as freezing, freeze drying, vacuum drying. Management of spent syrup is one of the most important pro...
