CCID TEATHgR REDUCED PE/iCH CROP IN UNIVERSITY ORCHARD 



During January peach budsinthe University orchard were subjected to mini- 

 mum temperatures of Ik to 18 belovr zero. These rainimum temperatures occurred t.rlco 

 during the donth about one rreek apart* On January 26, which was several days after 

 the last cold spell, a sufficient number of peach shoots to provide 100 or more buds 

 for e ach variety vrere brought into the laboratory ard examined to deteriTdne the nun>- 

 ber of buds v/hich T^ere still alive* The per cent of the total number of buds exam- 

 ined T.hich 7iere still alive was determined for each variety. 



Per Cent of Live _ Peach Buds in University Orchard{^ (January 26^19^1;) 



Group III - Bottom of Slope 



The orchard is located on a slope and- temperatures were lovrer at the bottom 

 than at the top. The varieties are grouped according to their position on the slope* 

 The varieties grouped vdth Elberta are at the top of the slope, while those grouped 

 with Golden Jubilee are in the middle. The varieties grouped vd.th Greensboro and 

 aiarigold are located in the bottom third of the orchard. It is not possible to com- 

 pare the hardiness of the varieties located in the coldest part of the orchard \fith 

 those in the warnier location. It is possible to compare the relative hardiness of 

 varieties in each group. 



In tfib RSifefirftft gretl|5 ftll isf tJte'Vferietiee except Redskin appear to be hardier 

 than Elberta, None of the varieties in the Golden Jubilee group are as hardy as 

 Golden Jubilee, but they had enough live buds left for a partial crop. 



In the bottom third of the orchard all of the varieties except Greensboro and 

 ilarigold had no live buds or so fevr left that the crop is a complete failure. The 

 Prairie varieties were se]e cted for hardiness, but apparently the minimura temperatures 

 which occurPedin the orchard were belovr the critical point for resistance to cold in- 

 jury* It appears that we have not yet developed peaches which will escape injury at 

 temperatures of 18 to 20° below zero,
