Why do flower seeds suddenly die after germinating? Home flower growing problem two
Problem: The seeds have already germinated, but suddenly died! You can try the following ways to avoid this happening: do not water too much, once the seeds have germinated do not water too much! Moisture will make the plants moldy or cause other diseases. Just keep the soil surface from drying out

A Detailed Guide to Sowing Geraniums and Their Germination Time
Geraniums can be sown in either spring or autumn, but indoor pot sowing in spring is best. The ideal germination temperature is 20-25°C. The seeds are not large, so do not cover them with too deep a layer of soil after sowing. They germinate in about 14-21 days. When sown in autumn, they can bloom in the summer of the following year. The above covers the sowing and germination time of geraniums.

Wax begonia seed propagation methods: sowing in spring and autumn, container sterilization and germination
Among the propagation methods for wax begonia, seed propagation is a relatively commonly used method. This method has been tested countless times, so the survival rate is still relatively high. Of course, the premise is that you must master the correct sowing method. So how do you propagate wax begonia by seed? Below, the editor will walk you through it.

Introduction to the Cotton "Dong A" Genic Male Sterile Germplasm Resource
In 1972, a male sterile cotton plant was discovered in the field, and after 3 years and 6 seasons of research, the cotton "Dong A" genic male sterile germplasm was successfully developed. Its male sterility trait is mainly controlled by a pair of recessive nuclear genes. It has the characteristics of stable inheritance of male sterility, easy transfer, strong combining ability, a wide range of restorer lines, a population male sterile plant rate of about 50 percent, and 100 percent male sterility per individual plant. It also has good yield potential and wide adaptability. Using the Dong A genic male sterile germplasm, 1 derivative male sterile line was developed. Among them, several derivative male sterile lines were further combined and screened to produce 12 hybrid

Introduction to the characteristics of the new high-yield soybean germplasm MN413
Origin and breeding process MN413 new soybean germplasm was developed in 1990 by sexual hybridization using the high-yield line MS8118 (subjected to plasma treatment N50 times, 30Kev) as the female parent and Yudou No. 10, and through bulk population and pedigree selection, it was stabilized in 1997 and named MN413 (Mengning 413). In 1998, it participated in the institute's variety comparison and identification, with an average yield of 239.7 kg per mu, an increase of 18.5% over Zhongdou 19, and in a 0.4-mu propagation field the yield reached 274 kg per mu; in 1999, it participated in multi-location trials in the province
