Jujube breeding has long been held back by a problem of timing. Its flowers are small and short-lived, pollen and stigma maturity often miss each other, and closely related species may bloom months apart. A new study presents a practical way to bring these biological clocks into alignment. By combining greenhouse temperature regulation, strategic heavy pruning, and repeated in vitro artificial pollination, researchers advanced the flowering of Indian jujube and synchronized it with Chinese jujub
