🌿 ¿Por qué el maíz soporta mejor el calor que otros cultivos? ¿Y cómo sobreviven los cactus en ambientes extremos?
La respuesta está en la fotosíntesis C3, C4 y CAM.
Si enseñas biología, fisiología vegetal o trabajas en agricultura, este video explica de forma visual uno de los conceptos más importantes para entender rendimiento y estrés vegetal.

🍂 ¿Tus frutales están botando hojas y no sabes si preocuparte?
En otoño, la caída de hojas no siempre es estrés: muchas veces es una estrategia fisiológica de supervivencia.
En este video explico:
✅ Abscisión foliar
✅ ABA y etileno
✅ Reciclaje de nutrientes
✅ Cómo distinguir normalidad vs problema en el huerto
Ideal para productores, asesores, estudiantes y docentes agrícolas.
oh neat
this thing also has an FM radio which is nice enough - it doesn't sound amazing but it sounds better than you'd expect - but if you're on a GMRS channel in the background and it gets activity, it'll silence the FM and play what's coming in on GMRS.
i mean idk maybe that's normal on these little HTs but I hadn't encountered it yet, nice little feature baofeng
What this does is let me have basically the same labels on here as I set up on the Midland 40W unit, instead of frequency which is the default. Why frequency? I _do not know_. GMRS is _channelised_. This radio _does_ let you _receive_ on arbitrary frequencies and lets you store like 1000 presets, which is _great_, but the default on the bottom 30 should bloody well be the defined channel numbers.
But no, big string of digits showing the frequency that literally no one in GMRS needs to care about. Arf.
There we go, that's much better. Had to use CHIRP to give channels names, but that's fine, it's way better than Baofeng's software anyway and now I have it set up on the pocket PC.
Also I definitely need to relabel these little handhelds Beifong insead of Baofeng.
i like how the donkey is wearing the kid's blazer and/or the kid is wearing the donkey's pants
If you have a #qrz1 Explorer HT and programmed it with CHIRP and it does a weird thing where it's receiving a signal from a repeater but it will not break the squelch, I found a workaround that should at least fix the issue for some of the repeaters:
In CHIRP go to View -> Show Extra Fields
In your saved QRZ-1 config find the affected repeater(s)
Change the Optional Signaling option to OFF
Save the config and upload it to the radio
