巴基斯坦采购需求：二倍体西瓜种子

I'm interested in sourcing black hybrid watermelon seeds for our upcoming cultivation projects. Could you please provide more details regarding the seed variety, including key characteristics, growth conditions, and yield potential? Additionally, I would like to know about your packaging options and pricing information for bulk orders. If possible, please include any certifications or quality assurance measures that you have in place. Looking forward to your prompt response!
