among these a Riparia glabre with large hardy leaves similar to those of 

 Grand glabre may be noted ; it is a suitable plant for the reconstitution 

 of the vine-3^ards in some districts of the province of Bergamo. 



Work carried out by the government nurseries 

 FOR American vines. 



i) Nursery at Acqui [Piedmont). -- This nursery was only established 

 in 1910 and has not yet produced plants which have been sufficiently 

 tested. Three numbers of Berlandieri x Riparia obtained at Astifrom seed 

 of Berlandieri Resseguier No. i from France, have been selected. .Some 

 Italian- American hybrids obtained in the Asti Nursery have been planted 

 permanently and kept under observation ; these were as follows : 

 lyambrusca X Ruspestris du I^ot 



These hybrids have up to the present remained exempt from phylloxera. 



2) Nursery at Asti [Piedmont). — This nursery is no longer under 

 government control and has been annexed by the anti-phylloxera associa- 

 tion of the district. Selections of Riparia and Rupestris and of some other 

 species have been inade but the results are of little value. 



Hybridisations were also carried out but they have not been continued. 

 (See the above paragraph). 



3) Nurseries at Cagliari and at Macomer [Sardinia). — For fifteen 

 years these nurseries have cultivated some numbers of Riparia, of Rupe- 

 stris, and of Berlandieri obtained from seed in the following institutions : 

 School of Vine-growing and Wine-making of AvelHno — School of Horti- 

 culture and Fruit-growing at Florence — Nurseries at Velletri and at 

 Barletta ; but these trials conducted in a single locality and in restricted 

 areas are not yet conclusive. It is possible to state, however, that the 

 plants are growing well and promise to be valuable. 



4) Nursery of Noto [Sicily). — The director, Dr. C. IMoxtoneri, 

 has obtained two varieties of Rupestris : — Rupestris Noto No. 2, and 

 RuDestris Noto No. 23, which are resistant to phylloxera, to drought and 

 to large amounts of lime in the soil ; they do well when used as cuttings 

 and as grafts and have a marked affinity for the native vines, to which they 

 give remarkable fertihty. Prof. Di Mattei, in his report to the Congress of 

 Noto in August 1914, advised the use of these two Rupestris in the place 

 of Rupestris du Lot which is very liable to " bramble-leaf " (roncet), and 

 predisposes the vine to abortion of the flowers. 



Rupestris Montoneri No. i and No. 2, which are also cultivated, are 

 both extremely promising.
