The red Delicious trees in the southwest 2;3 of ',.~ orc~ard appear to <br />have good fruit set and distribution in the t+i-r. Tl~.u•., spring <br />frostlfreeze damage was not a problem in t+,r ur,. Jed, r, ,• dos be. <br />activity inadequate for pollination this snriny. <br />2. Fruit set and distribution in th~ northern and t~+e east~,~+ ;~artions <br />of the orchard (to about three trees deep) does noL ma~: ~ [hat i~ the <br />rest of the orchard. The crop is much red„_rd and is rr~trictrd to <br />the middle 1/2 to 2/3 of the tree and only ,;n the under.,J~s of '_he <br />hranches (none nn the upper sides o.` the bra~~cbPS and it<~ on the uprial;t <br />leaders). 4ovrever, what fruit was `.here w; . in cl_~ste• .f four ti <br />five apples: those kill req~~rn spec al th •rnin; c, re utain .he <br />fruit gJality (size, color, a,+d shape; tha. .hill Lr co;,~.+r_ially <br />saleable, The occurrence of neav/ fruit s~ r (rn riust,r~., on th~~ un+er~- <br />sides of branches) is consistent wit!, the ;..ck n: ~priri cost/freen_ <br />damage this spring and with adequ t-~ bee ac`tvir~, !or ~ +''.+natio~+ <br />(otherwise there would be no such heavy fruit cl,+r„ ers;. <br />3.
