Il libro ha un'impostazione per gli studi universitari, è più uno sfizio perché guardo i semini sullo scottex e immagino la baraonda biochimica al loro interno :Sogghigna: Comunque è interessante, ora sto leggendo una parte sull'influenza della luce nella fase di germinazione: serve da segnale per i fitocromi coinvolti nel processo di "risveglio" del seme, alcune specie necessitano anche solo di pochi millisecondi di luce solare per dare inizio a questo processo altre vengono inbite dalla luce nello spettro del blu e dell'infrarosso. :blink:

Una lunga parte è dedicata ai cereali, perché è comunque un manuale più rivolto all'agricoltura su larga scala, comunque di tanto in tanto vengono nominati anche i peperoncini. Per chi fosse interessato agli spetti più scientifici lascio anche un link di articoli accademici solo sui peperoncini:http://www.ethno-botanik.org/Capsicum/Capsicum-literature-scientific-publications.html

Cercandoli su google troverete gli abstract, di qualcuno anche l'articolo completo.

E si infatti lo hai detto all'inizio : solo per i più "secchioni" <_<

 

Io purtroppo non ci capisco niente perchè a malincuore non ho nessuna preparazione tecnica in materia :bangin:

 

Comunque ho visitato il sito da te menzionato ed è interessantissimo ; almeno il tedesco lo parlo e lo capisco molto bene.

 

Ben vengano persone come te che in questo forum possono dare un contributo molto importante e costruttivo.

 

Auguri e buone cose :thumbsup:

Altrimenti usate Google Chrome e fate tradurre automaticamente in Italiano (per quelli come me che il tedesco non lo conoscono ovviamente) :thumbsup:
