MrMonkE 29 Posted March 7, 2013 Ik las over kits om met DNA de sex van een plantje te bepalen. Heeft een van jullie dat wel eens gebruikt? Quote Share this post Link to post Share on other sites

MeneerJansen 572 Posted March 8, 2013 de vraag is - hoe kunnen eenvoudige thuistelers een usb microscoop dusdanig hacken dat we dna kunnen zien. ccd chip + lens van een simpel laser aanwijslampje ...das genoeg om trichomen te kunnen insecteren. hoe kan je de volgende 10000(?) x vergroting simpel en goedkoop realiseren?

blowsterke 117 Posted March 8, 2013 Have you ever wanted to test your cannabis plant to see if it is a hermaphrodite? Well, Montana Biotech has a test for that! A cannabis plant will express hermaphroditic tendencies from environmental stresses or because of a genetic predisposition to express monoecious traits. A monoecious cannabis plant is a TRUE hermaphrodite. This cannabis plant will express male and female flower structures on the same plant. This is the hermaphrodite to be aware of! A true hermaphrodite sexes as a female early in the flowering cycle. A true hermaphrodite is a ticking time bomb! She/it will seed everything in your flowering room! Environmentally induced hermaphrodite cannabis plants can not be tested for, at this time, and do not pose the same risk to the rest of the room. These hermaphrodites are not “true” hermaphrodites and usually pollinate themselves. ANY cannabis plant can be induced to revert to a hermaphroditic state by stress. By stressing a cannabis plant, you have tapped into its inherent survival programming. Our motto is, “Know before they show…” Montana Biotech now offers a Polymerase Chain Reaction (PCR) based test for hermaphrodite screening of cannabis plants. KNOW if your cannabis plant has the TRUE hermaphrodite trait before you flower it! Hermaphroditism in the cannabis sub species Indica, Sativa, or Ruderalis can be defined in terms of two types, a True Hermaphrodite or an Environmentally Induced Hermaphrodite. I will try to define the subtle differences. Hermaphroditism in cannabis is a genetically influenced trait. Both true and environmentally induced hermaphrodites can be genotypically and phenotypically observed. A genotypic difference that can be observed between the two is the presence of both sex markers in true hermaphrodites. True hermaphrodites posses BOTH sex markers when analyzed using PCR techniques. A phenotypic difference is the appearance of fully defined male flowers at the beginning of flower production verses the appearance of a male stamen in a female pistil dominate flower after flower production had been initiated. A True hermaphrodite has both fully formed male and female sex morphology at the same time of flower induction. Polymerase Chain Reaction (PCR) techniques can be employed to determine the type of hermaphroditic tendency a cannabis seedling posses one week after germination. The genotypic difference of hermaphroditism is present by the time the first true leaf emerges after the cotyledons appearance. Een heel interessante site Monkee, dank je. http://montanabiotech.com/2012/02/16/break...annabis-plants/ Quote Share this post Link to post Share on other sites
parve 6 Posted March 8, 2013 als dit werkt dan is dit inderdaad een gemakkelijk en goed alternatief ga het denk ik wel effe proberen. gr parve Quote Share this post Link to post Share on other sites

cannabusinesss 50 Posted March 9, 2013 er blijft een comerciele kant aan zitten natuurlijk, heb niks gelezen maar wacht wel tot er hier bruikbare info word geroepen in gewone mensen taal. Quote Share this post Link to post Share on other sites
Tw!tchy 16 Posted March 10, 2013 Dit soort tests zijn al heel lang mogelijk, maar dit is verre van betaalbaar. DNA samples maken en analyseren gaat je nooit lukken zonder laboratoriumwaardig apparatuur, dus dit is totaal niet interessant voor kleine zelfstandige kwekers.

MrMonkE 29 Posted March 10, 2013 (edited) Ja ik denk dat je gelijk hebt. De kosten wegen absoluut niet op tegen het wachten op de sex. En daarnaast overtreedt het filmpje de derde wet van MrMonkE video annoyances: In een hand een camera vasthouden terwijl je iets uitlegt en met je vrij hand krampachtig dingen doen. Ik zal daardoor dit bedrijfje nooit serieus kunnen nemen. Raar maar waar. Edited March 10, 2013 by MrMonkE Quote Share this post Link to post Share on other sites
