We asked friends for help and have gathered a few points from Zhongdi Network on preventing and controlling grape berry cracking. The following is a detailed introduction for your reference. 1. Due to the heavy rainfall this year, during the fruit coloring stage the berries absorb water through the berry surface and roots, creating great turgor pressure inside the fruit, which has caused varying degrees of berry cracking in many grapes.

What does "flowers but no seeds" mean in rapeseed cultivation?
What is rapeseed "flowers but no seeds"? What methods are there to prevent and control it? Please explain. Rapeseed "flowers but no seeds", also called stunted sterility, means that from the onset of the disease to maturity, the plant keeps flowering continuously but cannot set seed normally. The main cause is a physiological disease caused by growing rapeseed on boron-deficient soil, mainly occurring in Brassica napus varieties, but in recent years it has also been found in Brassica rapa rapeseed. After the disease occurs, yields generally drop by 20% to 30%, and in severe cases there is even almost no harvest, making it a problem worth attention in rapeseed production.
