Question

Why does the staple leaves dries in new grape vine originated from seed?

Answer 1

Downy mildew, caused by the pathogen Plasmopara viticola, affects all parts of the grapevine but is most prevalent on the leaves. Lesions between veins on leaves appear yellow, reddish or brown.

Answer 2

Explanation:

Hey mate!

A piece of branch is cut off, dipped in rooting hormone and then placed in moist dirt so that roots and leaves form. Because they come from cuttings, new grapevines are essentially clones of the vine they were cut from.

Seedless grapes actually do contain seeds at some point. But a genetic error prevents the seeds from forming hard outer coats like normal seeds do.
