Potential and Actual Bud Fruitfulness: A Tool for Predicting and Managing the Yield of Table Grape Varieties

Microscopic bud dissection can be used to assess grapevine bud fruitfulness prior to winter pruning and long before actual bud fruitfulness can be measured in the vineyard the following spring. Bud dissections should be performed by qualified and trained personnel because inflorescence primordia are difficult to distinguish in some varieties. In the Puglia region, Southeastern Italy, in 2018 and 2019, potential fruitfulness using bud dissection and actual fruitfulness observed in the vineyard were compared for seventeen table grape varieties. The percentage of fertile buds, the number of inflorescence primordia (IP) per node, and the incidence of primary bud necrosis (PBN) were detected with bud dissection to be used either for managing winter pruning or for predicting yield during the successive season. The data were successively compared with fertile buds and actual bud fruitfulness observed in the vineyard during spring. The table grape varieties examined had similar values of fertile buds and fruitfulness both with bud dissection and in the vineyard. The application of longitudinal sections in bud dissections can be an alternative approach (or can be integrated into traditional cross sections) to distinguish IP in some difficult varieties, but the two techniques can be used together for more repeatable results. The bud dissection technique (with both cross and longitudinal sections) can provide useful insights for viticulturist to help guide winter pruning (intensity of pruning and number of canes) and to predict potential yield.

Effect of some postharvest treatments on properties of spear and peppermint herbs prepared for exportation

The present study was carried out in Sabahia Horticulture Research Station, Alexandria, Egypt, through the two successive season of 2010/2011 and 2011/2012. Two storage experiments in ambient atmosphere were conducted using natural drying (ND) and artificial drying (AD) spearmint and peppermint herbs. The packaging types paper bag of one single layer (p.s), paper bag of double layer (p.d), paper bag of one single layer, lined with plastic layer in side (p.s+po) and paper bag of double layer, lined with plastic layer in side (p.d+po), were tested. The experiment started on it October 2010 and October 2011 (12 months each). During each season of storage, the herb was sampled once every 3 months (5 samples). The essential oil % was determined by water distillation and the components of the oil were determined by (G.L.C). Results of this study can be summarized as follow:1-Artificial drying (AD) is fare better to keep the essential oil of spearmint and peppermint herbs at the accept level (AL) in the storage.2-AD kept the major components of herbs, carvon, menthone and menthol better than (ND). As well as the microbial load at low level.3-ND saved α-pinene, β-pinene and limonene at high level than (AD).4-Extended storage period resulted in the reduction of all the studied components of the two herbs. 5-Packaging containing polyethylene (po) showed superiority in their keeping capacities to their contents among all the tested ones.

437 PB 212 EFFECT OF SOIL FUMIGATION WITH METHYL BROMIDE ON MINERAL NUTRITION OF STRAWBERRY

This study was earned out on strawberry (Fragana × ananassa, Duch.) during the tow successive season of 1988/1989 and 1989/1990, at the strawberry Improvement Center Experimental Farm at Omm saber, south Tahreer, El Behira Governorate. The objective of this work was to study the effect of strawberry cultivar Douglas A split-plot design with four replicates was adopted. The results indicated a substantial increase in the content of the available macro and micro nutrients in the fumigated soils compared to the non fumigated ones. A significant increase in the number of leaves per plant, fresh and dry weight, early and total yield per plant was recorded. Fumigation accompanied by fertilization increased the available content (N,P and K and (Fe, Mn, Zn, and Cu) in the soil in the both growing seasons compared to fumigated only or the control. Plants grown in the fumigated fertilized plots contained the highest amount of macro and macro nutrients in both the growing seasons. Fumigated non fertilized plots had the highest amount of available P and K than all other treatment The maximum early and total yield per plant was obtained from the fumigated non fertilized plots.

Part III. Catalogue

At the end of each successive season, the collections of antiquities discovered at Brak and Chagar Bazar were divided into two parts, one of which was allotted to the Aleppo Museum, Syria, the other to the Expedition. The Aleppo Museum had the priority of selection. Any object marked (S) in the Catalogue was allocated to Aleppo. Of the remainder, the majority of the objects are in the British Museum, London, and smaller collections of antiquities were also sent to the Ashmolean Museum, Oxford, and to the Museum of Archæology and Ethnology, Cambridge. A representative collection of potsherds, a few complete pots, and some of the Eye-Idols were also sent to the London Institute of Archæology.All of the most important objects discovered by the Expedition have been illustrated in the eighty-six Plates of this final publication, or in previous numbers of Iraq. The Eye-Idols and the Golden Frieze from the Eye-Temple have been illustrated in colour in the Illustrated London News, in which short preliminary accounts of each season's work have been published; but obviously the information contained in those articles was only a very brief summary, and in many cases has been modified by subsequent discoveries.

VI.—Excavations on the site of the Roman city at Silchester, Hants, in 1907

I have the honour of submitting to the Society, on behalf of my colleagues of the Executive Committee of the Silchester Excavation Fund, the report of our investigations during the six months from the 17th May to 27th November of last year (1907), being the eighteenth successive season of our exploration of the site.In pursuance of the plan foreshadowed in last year's report, our investigations for 1907 were resumed in the grass field which occupies a considerable area near the middle of the Roman site.

XII.—On Dust, Fogs, and Clouds

Water is perhaps the most abundant and most universally distributed form of matter on the earth. It has to perform more varied functions and more important duties than any other kind of matter with which we are acquainted. From its close connection with all forms of life, it has been the subject of deepest interest in all ages. It is constantly changing from one of its states to another. At one time it is solid, now liquid, and then gaseous. These changes take place in regular succession, with every return of day and night, and every successive season; and these changes are constantly repeating themselves with every returning cycle. Of these changes, the one which perhaps has the greatest interest for us, and which has for long ages been the subject of special observation, is the change of water from its vaporous state, to its condensation into clouds, and descent as rain. Ever since man first “observed the winds “and “regarded the clouds,” and discovered that “fair weather cometh out of the north,” this has been the subject of intensest human interest, and at present forms one of the most important parts of the science of meteorology, a science in which perhaps more observations have been made and recorded than in all the other sciences together.
