Everything started when I decided to hop onto the train and sprout an avocado seed. So, I went to my local grocery shop in Spain and I bought a rather soft, small and black avocado (see below). It was of the "rugged" variety.
[21st of May, 2018]
Over the coruse of a couple of days the top part of the seedling started to warp and wrinkle. I assumed it meant that the cells inside started to consume water and nutrients from the seed or that, at least, the enzymes had started to catalyze the main mass into the necessary blocks for the embryo.
The hard "cap" had dettached and fell to the bottom of the beaker.
The seedling was left during holidays hooked to a watering system.
[13th of August, 2018]
The terminal bud had protruded and the seedling was entering its maturation phase, interesting red coloration around the hypocotyl with a whiteish terminal bud. It is also important to note that there was substantial shading, since temperatures are usually very extreme during summer in this part of Spain, the seedling was placed at a rather shady area.
[7th of September, 2018]
Pot was moved to a much sunnier area, hypocotyl presents darker red coloration. Some dried dots have appeared on it (failed leafs?). The terminal bud has differentiated into white and fleshy leafs (virus or albino form?).
Watering is checked on regularly.
Everything started when I decided to hop onto the train and sprout an avocado seed. So, I went to my local grocery shop in Spain and I bought a rather soft, small and black avocado (see below). It was of the "rugged" variety.
I cut the flesh of the fruit out gently (trying not to damage the seed inside) and cleant the surface with water. I then took a couple of nails and gently poked them into the seed, and later placed it into a sample beaker with tap water.

The seed was placed in a more luminous environment, wrinkling continued and no radicule was emerging from it.
[9th of June, 2018]
The seed started to crack from the bottom part, radicule tissue enlargement suspected. Some damage on the surface of the seed (resulting from the flesh extraction) was evident due to swelling.
[13th of June, 2018]
The radicule was spotted overnight, cracking had increased. A particular "cap" was covering the radicule on the tip.
[15th of June, 2018]
The radicule had grown in length, standing at about ~2 cm. The "cap" at the tip discolored and appears to be some sort of hard tissue.
[29th of June, 2018]
The radiucle had grown at about the entire length of the beaker (6.5 to 7 cm) and it was transplanted into neutral gardening soil and watered. No signs of secondary roots nor any terminal bud.
The hard "cap" had dettached and fell to the bottom of the beaker.

The hypocotyl had grown in length and some leafy and white structures can be distinguised in the terminal bud.
Pot was moved to a much sunnier area, hypocotyl presents darker red coloration. Some dried dots have appeared on it (failed leafs?). The terminal bud has differentiated into white and fleshy leafs (virus or albino form?).
Watering is checked on regularly.
[14th of September, 2018]
The terminal bud keeps producing the fleshy white phenotype of leaves, literature was checked for sun-blotch virus infection possibility.
