An investigation was carried out at the Bangladesh Council of Scientific and Industrial Research (BCSIR) Laboratories. Binodpur Bazar, Rajshahi during the period November 2006 to March 2007 to evaluate the physiological and biochemical composition of five cultivars of ber (jujube). Among the fruit cultivars, Thai kul produced the largest fruits (51.85 g each) having the highest pulp (92.38%) and juice (60%) and also the lowest vitamin C content (21.13 mg/100g). The fruit weight of the other cultivars varied from 9.6 0 to 45.09g. The seed weight ranged from 6.38 to 15.00%. Sugar content varied from 6.25% to 9.72% and starch content ranged from 0.715% to 0.963%. The apple kul had the highest qualitative score through organoleptic test while Thai kul had the lowest. The highest edible portion (pulp content) was in Narikeli kul (93.61%) and that of lowest in Apple kul (85.38%) and Local kul (85.38%) respectively. Considering all, fruit characters and yield are potential. Keywords: Ber, Cultivar, Fruit characters, Quality, Yield. DOI: 10.3329/bjsir.v44i2.3678 Bangladesh J. Sci. Ind. Res. 44(2), 229-232, 2009

Research to determine the ripening time of the fruit is the scientific basis for better harvesting and preservation. Physiological and biochemical methods were used to analyze the changes of some indicators according to the growth and development of banana fruit grown in Thanh Liet commune, Thanh Tri district, Hanoi from the time of its formation until the fruit ripening. The results showed that the banana reached the maximum size at 16 weeks old, at this time the peel was yellow due to the decrease in chlorophyll and increased carotenoid content. The content of vitamin C and total organic acid content reached their maximum when the fruit at 12 weeks old, then decreased gradually. Starch content increased to 14 weeks old, then decreased. Reduced sugar content increased gradually to 16 weeks old and then decreased. Protein content decreased gradually from fruit formation until fruit ripening, lipid content increased gradually to 15 weeks old, then decreased. Through the research process, we have determined that the physiological ripe time of banana fruit was 16 weeks old, this is the time when the fruit stops growing and accumulates many nutrients.

Sclerocarya birrea(A. Rich.) Hochst. is a multipurpose fruit tree which is very useful in providing food security and meeting nutritional and economic needs. This study was conducted to assess eighteen provenances ofSclerocarya birreaplanted in Mangochi, Malawi. The trial was assessed for fruit traits at fifteen years of age. There were significant (P<0.001) variations among the provenances in number of fruits, fruit weight, pulp weight, seed weight, fruit length, and diameter. Magunde provenance from Mozambique had the highest mean number of fruits, 2196 ± 200. Mangochi and Moamba provenances from Malawi and Mozambique were the most outstanding in the other parameters measured attaining the mean fruit weight of 20.89 ± 0.25 g and 25.67 ± 0.67 g, pulp weight of 25.70 ± 0.08 g and 21.55 ± 0.83 g, seed weight of 4.81 ± 0.35 g and 4.12 ± 0.18 g, fruit length of 2.61 ± 0.14 cm and 2.33 ± 0.07 cm, and fruit diameter of 2.33 ± 0.15 cm and 1.97 ± 0.08 cm, respectively. There was no significant (P>0.05) correlation between number of fruits and the other fruit traits. However, there were significant (P<0.05) and strong positive relationships between fruit weight and pulp weight (r=0.987) and fruit length and diameter (r=0.775). This suggests that fruit weight can be used indirectly for selection of pulp. Further studies should investigate fruit taste quality of products from the fruits.

The climate change and growing production of crops increase the demand for the water and the efficient use of water in agriculture becomes more critical. This experiment presents the results of research in the orchard with different irrigation programs and fertigation on yield and quality parameters of the ’Gala‘ and ’Fuji‘ apple tree. Three irrigation programs were applied IR + F – full irrigation with fertigation; IR – full irrigation without fertigation; NON‑IR – non‑irrigation, only natural precipitations. There were no differences observed among these three irrigation programs for tree diameter, sugar content, starch content and fruits firmness (P < 0.05). Significant deficit of water was in program IR and NON‑IR, at the length of annual growth, where the reduction was from from 680 mm to 440 mm at the ‘GALA’ variety. Statistically important differences between the irrigation variants were found out at the variety ‘Fuji’, in parametres yield, fruit weight and fruit diameter. Between programs IR + F and NON‑IR was the difference of fruit weight 25.6 g (14.3 %) and of fruit diameter 4.5 mm (5.8 %).

Chironja trees grafted on native grapefruit, sour orange, and Cleopatra mandarine rootstock were planted on Alonso clay and Coto clay at Adjuntas and Isabela Substations, respectively. Only native grapefruit and sour orange rootstocks were compared at Isabela. The experiments were conducted for the purpose of determining the possible effect of the three rootstocks on fruit weight, peel weight, number of seeds and segments (carpels) per fruit, and refractometer readings of the fruit (Brix) harvested from the grafted chironja trees. The most important results obtained were: Trees at Adjuntas grafted on grapefruit rootstock yielded heavier chironja fruits in 1962 and 1963, and a heavier peel in 1963, than those grafted on sour orange or Cleopatra mandarine rootstocks. In 1962, peel weights of chironja fruits from trees grafted on sour orange exceeded those obtained from trees grafted on mandarine rootstock. Fruits from chironja trees at the Isabela experiment grafted on sour orange rootstock had a significantly higher Brix than those from trees grafted on grapefruit rootstock, but no significant differences occurred among the other characters studied. No significant differences were found between chironja fruits from trees grafted on any of the three rootstocks as far as number of seeds and segments (carpels) per fruit, suggesting that rootstock species does not affect these characters. These studies suggest in general that the fruit from chironja trees grafted on grapefruit rootstock is larger, but less sweet, than fruit from trees grafted on either sour orange or Cleopatra mandarine rootstocks.

In this study, NaCl at varrious concentrations of 4 – 10 g/L was used to investigate the salt tolerance of in vitro shoot cuttings of Chrysanthemum indicum. Morphological, physiological and biochemical changes during the response of shoot cuttings in the salinity stress were analyzed. NaCl at 6 g/L reduced the development of shoot cuttings. Under salinity stress conditions, there have just a little reduction of the chloroplast in parenchymal cells near the midrib of leaf before they turn brown and die. Besides, carotenoid, starch content, and photosynthesis intensity were decreased. In contrast, respiration rate, proline and total soluble sugar content, and the activity of IAA and gibberellin were strongly increased. The application of IAA 0.25 mg/L, zeatin 0.1 mg/L and GA3 0.1 mg/L improved the shoot development in the salinity stress condition. Shoots in MS medium supplemented with BA 0.2 mg/L, NAA 2 mg/L and NaCl 6 g/L grow better in salinity stress condition.

Abstract Background The leaf age for harvesting flue-cured tobacco leaves is closely related to the quality of tobacco leaves, so an appropriate leaf age for harvesting is important for improving yield and quality of flue-cured tobacco, however, at present, there are few studies on effects of leaf age on physiological and biochemical changes during flue-curing and there is no clear standard of proper leaf ages for harvesting in production. Results In the Yunnan tobacco-growing area, an experiment was carried from 2016 to 2017 and different leaf ages were set. The results demonstrate that leaf age has a significant on tissue cell gap, leaf age and flue-curing stages exert significant effects on upper epidermis, palisade and spongy tissue, and leaf thickness of tobacco leaves. The thicknesses of upper and lower epidermis as well as palisade and spongy tissues at different ages show an approximately W-shaped change trend during flue-curing. With the advance of flue-curing stages, contents of starch, chlorophyll, carotenoid, and water in tobacco leaves at different leaf ages decrease, while polyphenol and malondialdehyde (MDA) contents increase. The older the leaf, the faster the chlorophyll, carotenoid, and water contents reduce, while the faster the polyphenol and MDA content rise during flue-curing. The flue-cured tobacco leaves at 116 DAT (days after transplanting) show the highest contents of total nitrogen and nicotine, followed by 123 DAT and those at 130 DAT are the lowest; however, the contents of total sugar and reducing sugar demonstrate a contrary tendency, and the starch content at 116 DAT is much lower than those in the other two treatments. The proportion of superior tobacco, average price, yield, and output value of upper tobacco leaves at different leaf ages are the highest at 123 DAT. The highest sensory evaluation score is found at 123 DAT, while that at 130 DAT is significantly lower in comparison with the other two treatments. Conclusions Tobacco leaves harvested at 123 DAT are mature and exhibit a low degree of membrane lipid peroxidation, moderate chemical compositions, and high economic value. 123 DAT improves availability of tobacco leaves.

The banana fruit reached its maximum size in terms of length and diameter at 18 weeks of age. The content of chlorophyll a in banana peel reached the highest value at 14 weeks old, chlorophyll b content reached the highest value at 12 weeks old and decreased rapidly. The content of carotenoid was low from fruit formation and then increased rapidly until the fruit is fully ripening. The vitamin C content and total organic acid content reached a maximum at 16 weeks old and then decreased until the fruit is fully ripened, the reducing sugar content increased continuously and reached a maximum at 18 weeks old and then decreased slightly. The starch content and pectin content reached a maximum when the fruit was 14 weeks old and then gradually decreased. The tannin content decreased from fruit formation until fruit ripening. Through the research process, we found that banana achieves the best quality to harvest when fruits are 18 weeks old. The results of this study provide important data for the harvesting and storage of banana fruit.

A comparative study on physiological and biochemical composition of ten varieties of mangoes was carried out at three maturity stages viz. immature, mature and ripe to find out the standard one. During the investigation, whole weight of the mangoes, pulp content, weight of peel and stone, total soluble solid (TSS), pH, acidity, sugar content and vitamin C were determined at three maturity stages. It was observed that all the varieties at ripe stages had higher sugar content as compared to immature and mature stages. Attractive flavour and pleasant taste were also developed in ripe stages and differed from one another due to varietal specific. This characteristics odour which appeared during ripening is due to ester and components of carbonyl types. Bangladesh J. Sci. Ind. Res. 41(1-2), 101-108, 2006

Poplar clone Kranti was selected to assess the morphological, physiological and biochemical responses under drought at different levels of water stress, as it is a common clone used to be grown in Uttarakhand for making paper and plywood. The cuttings of Populus deltoides L. (clone Kranti) were exposed to four different watering regimes (100, 75, 50 and 25% of the field capacity) and changes in physiological and biochemical parameters related with drought tolerance were recorded. Alterations in physiological (i.e. decrease in relative water content) and biochemical parameters (i.e. increase in proline and soluble sugar content and build-up of malondialdehyde by-products) occurred in all the three levels of water stress, although drought represented the major determinant. Drought treatments (75%, 50% and 25% FC) decreased plant height, radial stem diameter, harvest index, total biomass content and RWC in all the three watering regimes compared to control (100% FC). Biochemical parameters like proline, soluble sugar and MDA content increased with severity and duration of stress, which helped plants to survive under severe stress. It was analyzed that for better wood yield poplar seedlings should avail either optimum amount of water (amount nearly equal to field capacity of soil) or maximum withdrawal up to 75% of field capacity up to seedling establishment period (60 days). Furthermore, this study manifested that acclimation to drought stress is related with the rapidity, severity, and duration of the drought event of the poplar species.

Several population samples of Rubus idaeus subspp. strigosus Michx. (raspberries) were collected in British Columbia and northern Alberta and a number of characters were studied and compared with the cultivar Trent. Significant differences between populations were found for cane length, number of buds per cane, percentage of buds growing, number of inflorescences and flowers per bud, fruit and seed weight. There was a positive correlation between the total seed weight and the number of seeds, and between the total seed and fruit weight. No distinct types could be established based on location or elevation. None of the populations showed significantly better winter hardiness than the cultivar Trent, and although some had a specific character that was superior, none was found to have overall superiority.
