What to Do When Rose Leaves Dry Up? Cause Analysis and Solutions
There are five situations in which rose leaves dry up. The first is overwatering, and simply reducing the amount of water is enough. The second is insufficient light, and more than six hours of light per day is needed. The third is poor air circulation, and the plant needs to be placed in a ventilated spot. The fourth is excessively high temperature, and the plant needs to be placed in a warm spot. The fifth is pest infestation, and the pests need to be removed.

What to Do About Sweet Cherry Fruit Cracking? Cause Analysis and Prevention Measures
Causes of Sweet Cherry Fruit Cracking and Their Prevention Measures 1 Factors Affecting Fruit Cracking 1.1 Relationship Between Varietal Genetic Characteristics and Sweet Cherry Fruit Cracking It is generally believed that sweet cherry fruit cracking has a certain correlation with the characteristics of the variety itself, and sweet cherry cracking susceptibility is determined by genetic characteristics. The degree of cracking varies significantly among varieties, and the cracking susceptibility of the same variety also differs with different rootstocks. The cracking trait of the parents can be passed on to the offspring through inheritance. Yamaguchi et al. investigated the cracking behavior of 37 sweet cherry varieties and also found significant differences in cracking among varieties, which were positively correlated with fruit weight and flesh firmness. Greco et al. [Jishan Huayao] studied the cracking resistance of 30 sweet cherry varieties in the Apulia region of Italy, and the results showed that the cracking susceptibility of sweet cherries is related to genotype. Simon analyzed the cracking susceptibility of sweet cherry varieties and classified the cracking resistance of 51 major sweet cherry varieties grown worldwide into 5 levels: extremely resistant to cracking, resistant to cracking, relatively resistant to cracking, prone to cracking, and extremely prone to cracking. Among them, extremely resistant varieties include "Star" and "Sue"; resistant varieties include "Lapins" and "Sam"; relatively resistant varieties include "Summit", "Sunburst", and "Sylvia"; prone varieties include "Santina", "Stella", "Van", and "Sweetheart"; and extremely prone varieties include "Bing" and "Tieton". The cracking resistance performance of some of these varieties in Hungary differs slightly from their performance in China, which shows that the cracking susceptibility of the same variety also differs across different cultivation regions. Balbontín et al. used sweet cherry varieties with different cracking resistance as test materials and found that expansin genes are expressed at higher levels during the ripening stage of resistant fruits. Expansin genes can loosen the fruit skin cell walls and rapidly buffer cell wall tension, thereby preventing sweet cherry fruit cracking. Other studies have shown that fruit cracking is strongly correlated with the characteristics of epidermal cells at the fruit apex. Varieties with short epidermal cells at the fruit apex have milder cracking, while varieties with long epidermal cells at the fruit apex crack severely. Varieties with thick skin and neatly, tightly arranged cells are not prone to cracking; varieties with thin skin, large intercellular spaces, and loosely arranged cells are prone to cracking. Fruit cracking is related to poor skin extensibility and increased osmotic pressure of the flesh during fruit ripening.
