To distinguish clones or natural hybrids from pollen ultrastructure analysis. To evaluate the influence of rootstock, irrigation, environmental growth conditions and year of almond pollen characteristics. To gain better understanding on flowering biology and dormancy.
Project summary:
Significant differences occurred on almond pollen characteristics in relation to cultivar. No parameter of almond pollen (grain size and ultrastructural sculpture) was affected by irrigation or rootstock but grain size and pure diameter class distribution were significantly different for the three years and locations studied. Chemical changes and morphological growth in almond flower buds during winter dormancy occurred, mainly in trees grafted on peach.

Project objectives:
To study, in almond cultivars from different origin, the influence of cultural factors (rootstocks and irrigation) and geographical location on technological and nutritional characteristics of fruit.
To evaluate the compositional changes of almonds during growth, ripening and storage, in response to rootstock and water supply, in order to keep fruit quality as long as possible.
Project summary:
The chemical and technological characteristics where found to be greatly influenced by cultivars and, to a lesser extent, by rootstocks. Productive behaviour, pomological and chemical characteristics were strictly linked to the environmental conditions of three plantations located in Southern Italy.
Irrigation negatively affected the quality of kernels and stability of oil during 1 year of storage under simulated warehouse conditions.
Autoxidation of almond oil resulted closely correlated with the degree of unsaturation in the oil extracted at harvest time.

Evaluation of the performance of several almond cultivars on different rootstock in view of the improvement of the Apulian almond industry according new and modern designee. Vegetative and productive parametersare investigated.
Project summary:
Four self-incompatible almond cultivars "Cristomorto", "Ferragnes", "Nonpareil", and "Texas" and five selfcompatible Apulian almonds "false barese", "Filippo Ceo", "Genco", "Scorza verde" and "Tuono", were budded in September 1980 in the nursery onto almond seedling, peach seedling GF305 and peach × almond hybrid GF677. the budded trees were planted in an orchard at Valnzano, near Bari, in December 1981 spacing 6 m × 3 m, according to low headed-open centre training system and rainfed grown. The 1981-1995 vegetative growth and the 1984-1995 yield have been studied. The yield has been expressed as theoretical production of commercial kernel × hectare. An except of the study, involving part of the of the material and concerning the period 1982-1989, has been presented in 1990 (see Related publications). As concerns the rootstocks, GF677 proved to be the most vigorous followed by almond seedling and by peach seedling. In 1993, 87 % of the trees budded onto peach GF 305 had died and thus excluded from any further consideration. As regards the cultivars, "Texas" and "Ferragnès" showed a vegetative growth significantly higher than others.
On average, the overall 1984-1991 theoretical kernel production × hectare by the trees grafted onto GF677 and almond seedling was respectively 46% and 39% higher than that yielded by the trees grafted onto peach seedling. No significant differences in kernel yield were induced by the residue two rootstocks between 1984. The study confirmed once again the significant higher fruitfulness of the selfcompatible cultivars in comparison with self-incompatible cultivars.

Project objectives:
In a previous paper the hypotesis of the appearance of self-compatibility into prunus amygdalus L. genome following natural hybridization between Amygdalus webbi L. and Apulian cultivated almond has been put forward. On the basis of such hypotesis, selfed F1 kernels of 9 sweet and 5 bitterself-comatible Apulian almonds have been sown. The programme includes repeated seeding of consecutive generations of selfed kernels in order to observe whether morphological traits of A. webbii may appear within the off-springs population.
Project summary:
Kernels of the following sweet and bitter Apulian self-compatible almonds have been sown in 1991:
a) sweet almonds "Calò", "Ferrante", "Filipppo Ceo", "Genco", "Patalina", "Sannicandro", "Scorza verde", "Tuono";b) bitter almonds "Andria", "Cicerchia", "Gaetanuccia", "Padula de Ruvo", "Santeramo".
The kernel were obtained by controlled self-pollination. Fairly good germination percentages have been obtained (60,7% on the average) and individuals came into production within the fourth year from emergence. A second generation of selfed kernel has been obtained in 1995. The next step of the programme is the seeding of this material.

Introduction of self-compatibility into the genome of self incompatible almond cultivars of commercial importance by means of cross-pollination.
Project summary:
"Ferragnes", the well known French and self-incompatible cultivar, was artificially pollinated in 1988 with "False Barese", "Genco" and "Tuono", of Apulian origin and self-compatible. From n.1,206 seeds were obtained n.881 seedlings (average germination = 73,1%), as follows: n.310 "Ferragnes" × "Genco" and n. 278 "Ferragnes" × "Tuono".
At the end of the 1991, 10,8% of the n.881 seedlings were discarted for the stunted growth; 55,5% of the remaining n.786 seedlings were discarded at the end of 1992 because not yet into production; 7,9% of the residue n.297 seedlings were discarded in 1995 for the incidence of doubles above 5%.
Between 1993 and 1995, studies of flowering phenology, biological behaviour and production characteristics of the remaining n.227 seedlings were caried out: all the tested individuals were late blooming and about 60% were self-compatible. At the present, n. 11 offspring appear to be of particular interest in term of productivity and kernel characteristics, thereby deserving further observations; n.3 of therm belong to "Ferragnès" × "False barese", n.4 to "Ferragnès" × "Genco" and n.4 to "Ferragnes" × "Tuono".

Project objectives:
Evaluation of the role of "self compatibility", and importance of optimal pollination on the fruitfulness of almond cultivars.
Project summary:
Several comparative trials concerning the comparative fruit set potential and fruitfulness of selfcompatible and self-incompatible cultivars were set up.
1. The first two trials lasted 8 and 3 years respectively, involved a total of 11 self-compatible and 21 self-incompatible cultivars and were established in terms of fruit set and yield/tree following open pollination. Self-compatible cultivars set and yielded consistently more heavily than self-incompatible ones. The increase in fruit set and yield/tree ranged from 40% to 130%. The gap between the two biologically different group of cultivars was bridged only when pollination was estrused to honeybees in coincidence with excellent weather conditions during bloom. Self-compatibility in almond proved to be a genetic characteristics of horticultural interest.
2. A study to ascertain the highest possible fruit set following self-pollination of eight self-compatible cutivars of almonds was carried out in 1990. Fruits set from daily hand-selfing were high, compared to those from unassisted self-pollination. The results support growing most of the self-compatible Apulian almonds in solid blocks, without need for cross-pollination, provided that selfing is optimized by insect vectors.
3. A comparative study on fruit set induced by daily self- and cross-pollination was undertaken on selfcompatible Apulian almonds "Calò", "Filippo Ceo", "Genco" and "Tuono". Fruits set were satisfactory and not statistically different on average and within the same cultivar according to the method selfing or crossing. The results confirmed the possibility of growing Apulian self-compatible almonds in solid blocks, eliminating their dependence on cross-pollination.
4. The stigma/anthers reciprocal position in 15 self-compatible and 15 self-incompatible almond cultivars has been studied. No statistically different values of stigma anthers spatial distance were found according to the biological behavior of the cultivars. Moreover, self-incompatible almonds exhibited a more pronounced epistigmatism compared to self-sterile ones. The reciprocal. stigma anther position within the same flower should be interpreted just as a morphological trait of almond cultivars, totally independent of their biological behaviour.
5. Nowadays in Apulia (Southern Italy) there are good grounds for thinking that the wild vectors are inadequate to ensuring optimum fruit set of almond flowers. In order to compare the pollinating efficiency of introduced honey bees with that of wild insect vectors, flowering trees of 4 self-incompatible late blooming cultivars ("Ai", "Burbank", "Mission" and "Thompson") have been visited, on alternate days, by honey bees plus wild vectors of by wild vectors only. This was obtained by means "ad hoc" set up method, based upon the planned opening /closing of beehives and of insect-proof cages covering the trees. The study, carried out in 1989 and 1990, allowed to distinguish clearly the pollinating efficiency of the two kind of vectors: in comparison with wild insect vectors, honey bees increased the average fruit set by about 100%.

Project objectives:
Almond groves were identified in Apulia exhibiting "Stem pitting" and "Bud-line necrosis" alterations. Studies are now in progress to define the etiology of syndromes and to identify indicators of the genus Prunus which help making a timely diagnosis of alterations.
Project summary:
The wood disorders of almond, known as "Stem pitting" and "necrosis of the graft union black line", were described years ago from Apulia (Southern Italy), but their causal agents were not identified nor reliable diagnostic methods were developed.
Investigations were therefore initiated for establishing the nature of these diseases and identifying Prunus species and/or varieties as possible indicators for a quick diagnosis.
The results of graft transmission tests, assessed by observing symptoms on the wood after removal of the cortex, were positive. Stem pitting developed on cv Elberta peach seedlings and cv Cristomorto almond seedlings during the first and second years after grafting, respectively. Less clear-cut were the responses of inoculated seedlings to black line, except for P. cerasifera, which developed a stem pitting condition on the rootstock. Clearer symptoms (invaginations, pits and grooves at the graft union) were obtained when almond/almond and almond/peach graft combinations were used.

Project objectives:
Studies and investigations for new technologies for mechanical harvesting and post-harvesting of almond and other horticultural productions.
Project summary:
Harvesting and post-harvesting operations weigh heavily in terms of costs on the entire growing cycle of almonds since they require considerable labour.
In the tests of mechanical harvesting performed by the Institute of Agricultural Engineering satisfying percentages of detached almonds were obtained by every shaking machine utilized.
Mechanical harvesting even when integrated with manual harvesting of non-detached almonds, gave better results compared to traditional harvesting carried out only by hand. Remarkable increases in productivity can be obtained by using shaking-intercepting machines. As a matter of fact interesting results were recorded in the third harvesting chain, even though the tests were performed in new intensive almond-groves which had not been expressly arranged for mechanical harvesting.
The necessary phases of almond shelling and drying, which were performed by machines in this chain, recorded hourly capacities capable of treating the product harvested by the chain taken into examination as well as in other sites.

Project objectives:
To study the physiological and biochemical changes and responses involved in the mechanism of frost tolerance in almond trees. Moreover to analyze the genetic variability and in the way in which the technical events take place. The achieved Knowledge could be of great interesting in breeding programs and to direct the choice of the cultivar to the different environment.
Project summary:
The investigation will be done on: main enzimic systems, variation in sulflhydryl compounds, sugar metabolism during the flower bud development cycle, photosyntesis analysis; relation to freezing tolerance
