Palms are propagated through seeds. The attack of pests and diseases can be selected without accumulating palm seeds of mother palm, becomes high yield and a low yield as soon as possible and will be able to draw a bearing. Ripe fruits are collected from the mother palms piled up in four weeks to keep the shade. Condensed, lightness, holes in the extract from the fruit seeds of the fruit away germinating per cent efficiency savings will vary from time to time.

Palm seeds stored in the shade, but soon found that germination occurs. 51 per cent of the harvest in the shade during the germination of palm seed has 30 days to grow from 79 per cent seen during the germination. 

Seed germination of palm are two different methods of germination. Elongation of seed coat, elongated or germination occurs. Prior to the formation of the first leaf-like Besides coconut date palm seed coat grows downwards. During germination of the seeds from which 15 cm in length in order to maintain the first to eat the young leaves found lactose. When the leaves grow above ground using by lactose. 179-186 days after sowing the first leaves emerge. palm seeds in the germination, deficiency disorder from mother palm. Seed germination due to unexpected long-term seed dormancy considered unequal. Palm seeds, seed germination does not require 260 days. If you remove a portion of the flesh palm seeds found to germinate in a week after sowing. If you simply remove a portion of the flesh that will rise to 15 percent germination of seed germination by soaking for 30 minutes in cold water is revealed to be affected. Soak in water for three hours before sowing, palm seeds found that one hundred per cent may be capable of germination. Wet sand, rock soil, perlaite of 1: 1: 1 mix ratio by the rapid germination of palm seeds. Nutrient solution, when treated with growth hormones seed germination and seedlings will be significant differences in the phase. Potassium hydrogen phosphate mix with flesh seeds soak in the solution for 24 hours after the seed has been found to increase the germination percentage.
