I am doing crossing in rice , for pollination i keept panicles in pollination chamber in that sometime the panicle is not flowering well , what is the exact temperature , RH, and light i have to maintain for good pollen load from flower
The pollination in rice we must maintain a temperature within of 18-22 ºC, 65-70% RH, to avoid the appearance of diseases and moderate light.
I hope I've helped.
Rice is predominantly self pollinated crop but natural cross
pollination take place up to 3% depending upon varieties,
season and environmental conditions.
A blooming starts from tip of the panicle and proceeds
downward and continues for 7 to 10 days. Most of the flower
blooms with in 2 to 4 days from emergence of panicle.
Flowers open during morning hours between 9 to 11 hours
depending upon temperature (30 to 35 °C) and relative
humidity ( 70 to 80 %)..
Rice does well in a warm environment growth at 30 C during the day and 24 C at night would be ideal with a 12 daylight and 12 night schedule. High relative humidity would be favorable to good growth but for producing pollen that flows I suspect at lower relative would be favorable when the anthers start emerging you may want to lower the RH from 75 to 50%. For good pollen viability make sure the plant was well nourished with micronutrients such as Zinc and Boron.
