五月份並非嫁接的季節，但是我想實驗看看
Experimental grafting of fruiting Kieffer pear onto non-fruiting Bradford pear tree in late May.The first picture is the Kieffer scion and the last two are the Bradford pear branch selected and the finished result. Stay tuned......
Dear Joe,
ReplyDeleteNice work! Hope it won't turn out to be a hybid monster. Hahaha.

Dear Wei:
ReplyDeleteI am battling the fire blight with my disease susceptible Bartlett and Moonglow pears. Kieffer is the only disease free cultivar. Had I known before I would not plant any pears except Kieffer.

Dear Joe,
ReplyDeleteI am sorry to hear about it. Since you have been doing some hybriding, how about crossing over Bartlett with Kieffer and doing the same thing with Moonglow to acquire fire blight resistance from Kieffer?

Dear Wei:
ReplyDeleteGood thinking! However, you can't graft Kieffer onto Bartlet rootstock because the rootstock is still susceptible. The bacteria can attack the bark and trunk and kill the entire tree. All commercially available varietal trees, be it Kieffer, Bartlet, Moonglow, or even Bradford are all grafted onto a very primitive pear tree rootstock. It seems to be the rule of nature that anything that is good and desirable will always weak and disease-prone. I've pretty much accepted the fact that my Bartlet and Moonglow are destined to doom. I have trimmed off the diseased limbs and leaves and sprayed the tree with Streptomycin but the disease is in the whole tree system. One cannot fight Nature.

Dear Joe,
ReplyDeleteHow true that Nature still rules.
