afs-71650	Valmari, Arvi; Valmari, Irja	On the frost resistance of red clover with special attention to seed production	1966	22	.pdf	application/pdf	9923	533	69	Well- ripened seeds tolerate frost quite well as a rule, also seeds of clover (according to the present investigation those borne in dark-brown heads). The estimate can therefore be made that in the region of which Pelso is representative, fields in cultivation for clover seed will rarely be subjected in autumn to frost of greater severity than in the present test, perhaps so rarely indeed that a risk of that magnitude would be taken without hesitation in actual farming.	cache/afs-71650.pdf	txt/afs-71650.txt
