The invention is a new and distinct variety of Grape plant named Juneaudor prcoce that is characterized by its grape clusters with shoulders that are loose in density, its very early fruit maturity period, its vigorous growth habit with high fruit productivity, its good fruit set, its grapes that have thick skins, and its grapes that produce wine that is rich in aroma, juicy, vinous with a fruity taste.

A new distinct variety of grapevine named ARRATWENTYTHREE abundantly forms attractive meaty seedless berries with a dark red violet skin coloration; in dense medium-to-large clusters which display a naturally sweet flavor. The fruit commonly is ready for harvesting during August in San Joaquin Valley of Central California, U.S.A, and displays good eating qualities as a table grape. The fruit firmness renders the fruit well amenable for handling, shipping, and storage.

Disclosed are a small molecule compound for enhancing plant stress resistance, a preparation method therefor, and application thereof. Specifically, disclosed are compounds as shown in formula I, salts thereof, optical isomers thereof, racemes thereof, solvates thereof, or precursors thereof. Moreover, the compound of the present invention is a substitute of ABA, can significantly improve the plant stress resistance, and thus has an extremely wide application prospect.

A new grape variety distinguished by its strong blistering of the upper side of the leaf blade, cuneiform shaped leaves, fruit cluster of medium bunch density with 3-4 wings, medium harvesting time (early September in northeastern Italy), and resistance to downy mildew and powdery mildew.
